Synthesis method

Industrially, acetyl chloride can be produced by reacting ethylene with hydrogen chloride, or by reacting sodium acetate, sulfur dioxide and chlorine. Laboratory can be produced by reacting acetic acid, sodium acetate or acetic anhydride with various chlorinating agents. For example, it is obtained by reacting acetic anhydride with chlorosulfonic acid (or hydrogen chloride, carbon tetrachloride, or phosgene). It can also be obtained by reacting glacial acetic acid with benzoyl chloride (or silicon tetrachloride, phosphorus trichloride, chlorinated sulfurous acid, or phosphorus pentachloride). Operation Example 1: The ingredient ratio (molar ratio) is glacial acetic acid:phosphorus trichloride=3:1.2. Add glacial acetic acid to the reactor, stir slowly, and add phosphorus trichloride dropwise at room temperature within 10-15 minutes. Heat to increase the temperature and maintain 40-50°C for 0.5 hours. The reaction product is allowed to stand and separated to obtain crude acetyl chloride with a pure yield of about 70%. Operation Example 2 In a 3L three-necked flask, put 360g (6mol) glacial acetic acid and 552g toluene, heat to 50°C, add 510g (3mol) silicon tetrachloride dropwise within 30min, and keep it at 50°C until the hydrogen chloride gas is no longer violent. until it escapes. Then carry out fractional distillation and steam until the temperature at the top of the column is 80-85°C to obtain the crude product. The fine product is distilled again, and 50-65 fractions are taken to obtain 400g of acetyl chloride, with a yield of 85%.

Properties and stability

1. Volatile and toxic. It has a tendency to self-polymerize and is easily oxidized by air. After oxidation, chlorine, hydrogen chloride, phosgene, formaldehyde and peroxide are generated. At the same time, this peroxide can promote the polymerization of monomers. It can form copolymers with various ethylene derivatives (such as vinyl chloride, styrene, etc.). Therefore, it is necessary to add a polymerization inhibitor or seal it with an aqueous solution of nitrogen, carbon dioxide, and alkali. Copper or brass poses a risk of forming explosive acetylene compounds.

2. It is easily polymerized under the action of light or catalyst, and can be copolymerized with vinyl chloride or acrylonitrile. It easily undergoes an auto-oxidation reaction with oxygen in the air to generate peroxides that are dangerous to explode. Peroxide slowly decomposes to form formaldehyde, phosgene and hydrogen chloride. Generally, a small amount of hydroquinone, phenols, and alkylamines are added as stabilizers. It reacts with chlorine at 40~50℃ to generate 1,1,2,2-tetrachloroethane. In the presence of anhydrous ferric chloride or aluminum trichloride, it reacts with hydrogen chloride to generate 1,1,1-trichloroethane.

3. Irritating skin and eyes. Inhaling high-concentration vapor can cause central nervous system paralysis and coma. Long-term inhalation of low-concentration vapor can cause damage to the liver and kidneys, and can cause tumors in animals and humans, so please pay attention to ventilation when using it. The inhalation lethal concentration for mice is 25209.5 mg/m3. The olfactory threshold concentration is 1985mg/m3. The maximum allowable concentration in the workplace is 40mg/m3 (USA).

Storage method

Storage Precautions[25] Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37°C. The packaging must be sealed and must not come into contact with air. They should be stored separately from oxidants, acids, and alkalis, and avoid mixed storage. It should not be stored for a long time to avoid deterioration. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

1. Vinyl chloride chlorination method: Vinyl chloride is obtained by chlorination and alkaline hydrolysis. During the chlorination reaction, dichloroethane and s-tetrachloroethane are generated; during the alkaline hydrolysis process, 1,2-dichloroethane is generated. Among them, 1,1,2-trichloroethane is produced by removing hydrogen chloride to produce vinylidene chloride, which is a commonly used method in industry. According to the different alkali used, it can be divided into sodium hydroxide method, calcium hydroxide method and ammonium hydroxide method. The final product of the former has many by-products with a boiling point lower than 30°C and a high content of calcium acetylene chloride, but there is no environmental pollution; the final new technology of the latter has no by-products of calcium chloride and sodium chloride, and post-processing is easy. When using hydroxide, strong stirring is necessary to reduce the possibility of foaming, correspondingly increase the utilization factor of the equipment, and the amount of chloroacetylene generated can also be reduced to 1/10.
①Sodium hydroxide method:This method can be divided into two types. One is that all reactions are carried out in a continuous reactor, the batching ratio (NaOH:CH2ClCHCl2) is (1-1.2:1), and the content of sodium hydroxide is 10%-20%. The reaction temperature is 50-70°C, the product content is 94%, and the yield is 93.9%. The second method is to use sodium chloride-containing sodium hydroxide and 1,1,2-trichloroethane to convert into vinylidene chloride. This method directly uses electrolyte, and the sodium chloride generated after dehydrochlorination can be returned to the electrolysis system for recycling. Therefore, it is most suitable for the production of vinylidene chloride in chlor-alkali plants.
②Calcium hydroxide method: This method can be divided into four types. First, the raw material calcium hydride concentration is 200g/L, the calcium carbonate concentration is <20g/L, the calcium hydroxide excess is 50%, and the system temperature is 80°C at the beginning of the reaction, and then rises to 90-92°C. The crude vinylidene chloride obtained after the reaction is purified by distillation, and the yield can reach more than 80%. Secondly, since the control step of the reaction to generate vinylidene chloride is material transfer at the interface, a small amount of surfactant and water should be added to improve the contact effect. Third, in order to simplify the process, the reaction and distillation are combined in one tower. Fourth, first carry out the addition reaction of vinyl chloride and chlorine through the reactor, and then add 10% calcium hydroxide to convert 1,1,2-trichloroethane into vinylidene chloride. After refining, the product vinylidene chloride is obtained. Ethylene chloride.
③Ammonium hydroxide method: Xudao Company proposed to use ammonium hydroxide to replace sodium hydroxide and calcium hydroxide. The feed ratio is NH4OH:CH2ClCHCl2=2:1 (mol), the reaction temperature is 120℃, and the pressure is about 0.86MPa, conversion rate 52.1%, ammonium chloride, ammonia and unreacted 1,1,2-trichloroethane can be recycled. The chlorination reaction is carried out in a tower reactor. The tower is filled with trichloroethane. Iron rings are stacked in the tower as a catalyst. Chlorine and vinyl chloride are introduced from the bottom of the tower in a ratio of 1.05:1 (mol). The reaction temperature is controlled at 35-45℃. Since the reaction liquid of vinyl chloride and chlorine gas can circulate naturally depending on the temperature difference, it can also be forced to circulate using a pump. The reaction temperature is about 75°C and the pressure is normal pressure. The generated vinylidene chloride passes through the rough separation tower on the kettle and then through the rectification tower to purify and refine the product vinylidene chloride. At present, all domestic factories use kettle-type alkaline hydrolysis reactors, most of which operate intermittently. In the past, some people used 2.5%-3.0% milk of lime as alkali solution, but later switched to dilute sodium hydrochloride solution due to clogging of equipment. In the intermittent operation, the reaction temperature was raised to 85°C in the later stage of alkaline hydrolysis. As a result, the impurities in the crude vinylidene chloride increased significantly, which made refining difficult.

2. Alkaline chlorination method of ethyl chloride: This method uses 1,2-dichloroethane as raw material, and chlorides it into 1,1, 2-Trichloroethane, in addition to 1,2-dichloroethane and chlorine, 12% ethylene is also added to the reactants to accelerate the chlorination reaction of dichloroethane. Trichloroethane is purified in a low-boiling tower and a high-boiling tower and then reacts with a dilute alkali to remove a molecule of hydrogen chloride to obtain vinylidene chloride; crude vinylidene chloride is refined in a low-boiling tower and a high-boiling tower to obtain pure vinylidene chloride. Ethylene Products. The chlorination yield of the above process is 95.4%, the alkaline hydrolysis yield is 99.8%, and the product purity is as high as 99.9%.

3. Methyl chloroform thermal cracking hydrogen chloride method: This method uses vinyl chloride as raw material, and is added with hydrogen chloride to generate 1,1-dichloroethane; dichloroethane is chlorinated at a high temperature of 480°C , the main chlorinated liquid products obtained are vinylidene chloride, methyl chloroform (1,1,1-trichloroethane) and vinyl chloride. By-products include trichlorethylene, cis-dichloroethylene, trans-dichloroethylene, polychlorethane and hydrogen chloride. The chlorinated liquid is distilled to separate the above products, vinyl chloride and hydrogen chloride are returned to the addition process, trichlorethylene is sold as a commodity, methyl chloroform is cracked into vinylidene chloride by high temperature, the cracked mixture and the chlorinated liquid are combined and separated by distillation. Polymerization inhibitor is added to vinylidene chloride for sale as a commodity. 1,1-dichloroethane and 1,2-dichloroethylene are chlorinated in liquid phase at low temperature to form 1,1-dichloroethane and tetrachloroethane, and then sent to Enter the high temperature chlorinator.

4. Ethane chlorination and thermal cracking to remove hydrogen chloride: This method uses ethane as raw material, which is chlorinated at a high temperature of 426.6°C into hydrogen chloride, vinyl chloride, vinylidene chloride, ethyl chloride, A mixture of 1,1-dichloroethane and methyl chloroform is used to separate the above product by fractional distillation. Hydrogen chloride is used in the vinyl chloride hydrochlorination reactor; methyl chloroform is cracked at high temperature to decompose a molecule of hydrogen chloride to generate vinylidene chloride, which is combined with the chlorinated liquid for separation and purification to obtain the high-purity product vinylidene chloride.

5. High-temperature thermal dehydrochlorination method: First, preheat 1,1,2-trichloroethane to 250°C, and then pass it into a tubular reactor for decomposition reaction. The reaction temperature is 350-500°C. The advantage of this method is that the decomposition product hydrogen chloride can be utilized, but the by-product 1,2-dichloroethylene is more.

Purpose

1. This product is a copolymer based on (containing at least 80%), which can produce polyvinylidene with fire resistance. Various synthetic resins can be produced by copolymerizing 1,1-dichloroethylene with acrylonitrile, butadiene, acrylate, styrene, etc. Vinylidene chloride resin can be processed into fibers or films and used for surface coatings on paper or plastic films. Polyvinylidene chloride fiber can be used to produce fabrics, tents, insect nets, car seat cushions, etc. Polyvinylidene chloride film has lower air permeability and moisture permeability than other plastic films, and is suitable for food packaging. Copolymers with methacrylic acid, methyl methacrylate, etc. can be used in the film industry. Mainly used as raw material for the manufacture of vinylidene chloride resin and 1,1,1-trichloroethane. Because of its high volatility, it is usually not used as a solvent.

2. Used in the manufacture of various copolymers, synthetic fibers, adhesives and organicsynthesis. [26]

Synthesis method

Obtained from the reaction of anthranilic ether and acetic anhydride. Put the measured amount of o-anisole into the reaction kettle, and add glacial acetic acid under stirring. Add acetic anhydride dropwise at 10 to 12°C, finish the addition in about 2 hours, and let it stand for 2 hours to obtain the intermediate o-acetamidoanisole for industrial use. The ingredient ratio is anthranilate: glacial acetic acid: acetic anhydride = 1:0.9:1 (weight ratio). You can also mix anthranilate and acetic anhydride, reflux in a sand bath for 2 hours, let cool, obtain needle-like crystals, filter, wash away the acidity with water, and then recrystallize with water to obtain the finished product.

Purpose

1. Organic synthesis. Used as raw material for organic synthesis, used in the manufacture of pesticides, medicines, etc. Preparation of aniline yellow and other dyes.
