敌敌畏是以敌百虫和20％碱液为主要原料,生产过程主要有碱解和脱苯两工序组成。碱解岗位的任务是按一定的配比即敌百虫:水:苯:20％碱液=1:(2～2.3):(1.2～1.3):1.05(重量比),分别按敌百虫水溶液、苯、20％碱液先后顺序地投入碱解锅进行反应。反应温度控制在65℃,最高不超过70℃(用-10℃冷冻水调节),反应生成敌敌畏粗油后,经输送泵将碱解锅内的粗油送到油水分离器进行连续分离,粗油流入粗油受槽。
Dichlorvos is a trichlorfon and 20% lye as the main raw material, the production process is mainly composed of alkaline hydrolysis and benzene off the two processes. The task of alkali hydrolysis post is according to certain proportion namely trichlorfon: water: benzene: 20% lye = 1: (2 ~ 2.3) :( 1.2 ~ 1.3): 1.05 (weight ratio) Aqueous solution, benzene, 20% lye sequentially into alkali hydrolysis pot reaction. The reaction temperature is controlled at 65 ℃, the maximum does not exceed 70 ℃ (with -10 ℃ frozen water regulation), the reaction of dichlorvos crude oil produced by the pump will be sent to the alkali hydrolysis pot of crude oil to the oil-water separator for continuous separation, crude Oil flows into the crude oil by the tank.
