chloride; 3- -1- 3- -[1] propylene; propylene chloride;α- allyl chloride allyl chloride allyl chloride;;; allyl chloride English Name: Allyl chloride English synonyms: 3-CHLOROPROPYLENE; 3-CHLOROPROPENE; 3-CHLORO-1-PROPENE; ALLYL CHLORIDE; 1-Chloro-2-propene; 1-Chloropropene-2; 1-Propene, 3-chloro-; 2-Propenyl chloride storage conditions: Refrigerator aqueous solubility of:3.6 G/L ( 20 º C ) freezing point :-134.5 Allyl chloride synthesis method and usesChemical properties : colorless, flammable liquids, corrosive and irritating smell. Slightly soluble in water, ethanol, diethyl ether, chloroform and petroleum ether immiscibility and uses: can be used to produce epichlorohydrin, propylene glycol, glycerol and other intermediates, used as special reaction solvents, pesticides, pharmaceuticals, perfume, and coating materials. Used in organic synthesis and the pharmaceutical industry, also known as 3- allyl chloride allyl chloride, is a raw material for organic synthesis, in pesticide for synthesis of monosultap, dimehypo and cartap intermediates N, N- two methyl allyl amine and pyrethroid intermediates propylene alcohol ketone, in addition is also medicine, synthetic resin, coating, spices and other important raw materials. The product has the olefin and alkyl halides reactivity, glycerin, epichlorohydrin, allyl alcohol and other organic intermediates. Also used in pesticide, pharmaceutical raw material. Can also be used as a synthetic resin, paint, adhesives, plasticizers, stabilizer, surfactant, lubricant, soil improvement agent, spices and other fine chemical raw materials, mainly used in the manufacture of epoxy chloropropane, glycerol, chlorine alcohol, allyl alcohol, pesticide Shachongshuang, pharmaceutical, resin, paint, adhesives, and acrylic acid sodium, lubricant and so on. In organic synthesis, pesticide, paint, synthetic resin, also used as an adhesive, lubricant and other production methods: 1 high temperature chlorination of propylene and chlorine in high temperature chlorination reaction; process as follows; dry propylene ( fresh propylene circulating propylene: =1:3 ) heated in the preheating to 350-400 , the reaction tower entrance, mixed with chlorine ( =1:3 chlorine: propylene ), via a special nozzle is sprayed into the furnace, the furnace temperature is 500, the reaction heat preheating propylene chloride. Propylene conversion per pass for 25%, chlorine into chemical calculation, allyl chloride with the total yield of 80-85%, in addition to the main product of allyl, and 1,2- two, 1,3- two allyl chloride allyl chloride, hydrogen chloride, 1,2,3- three chloro propane and other small amount of by-products. Chlorination reactants quench to 50-100 , to remove the hydrogen chloride and propylene, the fractionation and allyl chloride. For an annual output of 1. 350000 t allyl chloride device, about consumption per ton of product of propylene 700kg, chlorine 1120kg. 2 oxychlorination with propylene as raw materials, with tellurium as catalyst, through the following reaction of allyl chloride; propylene, hydrochloric acid and oxygen by 2.5-1:1:1-0.2 ( molar ratio) in the case of mixed. Reaction at 240 , 0.101MPa conditions. Reactor for fluidized bed, catalyst is carried on a carrier V2 O5 H3 Te PO4, and add the nitrogen compounds as promoters. Selective 90% above, fluidized bed space time yield of greater than 100g allyl chloride catalyst /L•H. In small batch production, can be obtained by allyl chloride; at 10-20 to allyl alcohol sulfate, cuprous chloride and hydrochloric acid. With Billy, thermal response 5h. Static stratified, divided into lower mixed acid, an upper liquid washing 1 times, 5% sodium carbonate solution washing 1 times, and then washed 1 times, divided as water, distilled collection 40distillates, to allyl chloride. Yield of 73%.
