Usage:
Mainly used as medicine and pesticide raw materials, especially for butachlor, alachlor and other herbicides production.
For pesticide dimethoate, fluoride acetamide, medicine, solvents, refrigerants, fire extinguishing agent, to help agent, lubricants, such as the production of additives. Chloroacetyl chloride wide range of uses, there are only three series of herbicides more than 40 varieties need to consume chloroacetyl chloride.
Brief manufacture process:
Chloroacetic acid as raw material
Chloroacetic acid chloride in the presence of slightly heated, available chlorine chloride, chlorination of phosphorus trichloride, phosgene, thionyl chloride, etc., generally used phosphorus trichloride chlorination agent, the reaction temperature is 50 ~ 60 ° C. The method has the advantages of low cost and easy access to raw materials. In industrial production is also useful for acyl chlorination of phosgene, the reaction is convenient, no waste generated, and the laboratory commonly used thionyl chloride chloride chlorination agent. In addition, chloroacetic acid chloride chlorination method can also be used, the cost is low, but the reaction process of hypochlorous acid formation.
