| Abstract: | This article has described the new process preparing chloropivaloyl chloride(CPC) by continuous vapor-liquid two phases chlorination reaction of pivaloyl chloride,the reactive distillation technique(RDT) which incorporates chlorination reaction and distillation were possible of refraining from chlorination deeply,high conversion of pivaloyl chloride and high selectivity of chloropivaloyl chloride were achieved,process and equipment were simplified strongly,this technological process was of practical value in designing same or similar plant and optimizing operation. |
