Three chloroacetic acid is an important chemical raw material. Process Description: the degree of heating to 60-70 reactor production will be 0.85 tons three Trichloroacetaldehyde 98% nitric acid and 1 tons of 99.5% addition of 200L in the reaction of chloroacetic acid to produce liquid semi-finished products three. Then go to the 500L distillation kettle, heating, vacuum distillation, the product after condensation, crystallization, that is, 99.5%, three, 0.975 tons of chloroacetic acid crystals. The reaction rate is about 90%. Reactive distillation temperature is about 90-100 degrees, 10% of excess nitrate decomposition.
【技术实现步骤摘要】
一种三氯乙酸生产工艺1)主要原辅材料(2)工艺流程说明生产时将0.85吨98%硝酸和1.0吨99.5%的三氯乙醛加入200L的反应釜中加热至60-70度,发生氧化反应,生成液态三氯乙酸半成品。然后转至500L的蒸馏釜中加热减压蒸馏,产品经冷凝、结晶后即得99.5%三氯乙酸晶体0.975吨。本反应得率约为90%。反应蒸馏温度约为90-100度,过量硝酸有10%的分解。
