production method | ethylene hydrogen chloride method is widely used in the industrial production of ethyl chloride, a few use of ethane chloride method, very few use of ethanol method. Ethylene hydrochloride is prepared by the addition reaction of ethylene and hydrogen chloride as raw materials. The technology and economy of this method are reasonable, there are two kinds of gas phase method and liquid phase method. In the liquid phase method, in the presence of a catalyst such as AlCl3, a high concentration of ethylene is used to react with hydrogen chloride in a solvent such as ethyl chloride (30-40 ° C., 253-303kPa), alkali washing is followed by gas-liquid separation and distillation to obtain a pure product. Gas phase method is based on AlCl3, NH4Cl, silica gel as catalyst, with a lower concentration of ethylene ethane mixture as raw material, in the reaction of 130-250 deg C. 2. The ethane chlorination process is mainly based on the thermal chlorination process in the industry, that is, the chlorination reaction of ethane at 250-500 ° C. Under a pressure of 202-304kPa (by-product hydrogen chloride and ethylene reaction, can also be prepared by ethyl chloride). 3. The ethanol method consists of the reaction of ethanol with hydrochloric acid in the presence of zinc chloride. Raw material consumption quota: ethanol (95%)945kg/t, hydrochloric acid (30%)2830kg/t, zinc chloride 90kg/t. In addition, the tail gas after absorption of hydrochloric acid, which is a by-product for the production of trichloroacetaldehyde, is dried with 98% sulfuric acid, and then pressurized, frozen, liquefied, and purified by rectification to obtain ethyl chloride. There are several preparation methods. (1) ethylene and hydrogen chloride addition this method is divided into two methods: Gas phase method and liquid phase method. Gas phase method: Ethylene and hydrogen chloride by aluminum chloride, bismuth chloride catalyst, reaction temperature of 130~250 deg C, get ethyl chloride, and then distillation product. CH2 = CH2 + HCl → CH3CH2Cl liquid phase method: anhydrous hydrogen chloride and dry ethylene are passed through a reactor filled with vinyl chloride-aluminum trichloride liquid and reacted at 30~40 ℃ under pressure of 245 ~ 294kPa, the product is obtained by flash evaporation, alkali washing and distillation. (2) ethanol method ethanol and hydrogen chloride gas bubbling through the 70% ~ 80% zinc chloride aqueous solution reaction to generate ethyl chloride crude, and then use the alkali solution to neutralize the hydrogen chloride contained in ethyl chloride, dry the water in ethyl chloride with concentrated sulfuric acid, and wash off ethers, and then by condensation to obtain the finished product.
