摘　　要：针对目前国内邻(对)氯氯苄生产工艺存在的主要问题,通过改进氯化合成工艺,采用先进的反应精馏和碱洗脱酸技术,大大提高了反应转化率和碱洗脱酸效果,其中反应转化率达到了75%以上,产品纯度达到了99.5%以上,从而有效地降低了生产成本,减少了环境污染,经济效益和社会效益显著,具有很好推广应用前景。According to the main problem of o (p)-chlorobenzyl chloride process in domestic, through improving chlorinated synthesis process, using advanced technology of reacting rectification and cleacidify by alkali washing, the inversion rate and the effect of alkali cleacidify were improved greatly. The reaction conversion rate was over 75%, the purity of products exceeded 99.5%. Therefore, production cost was cut down environment pollution was reduced. Economic and social benefits were obvious. It had good prospects of application.
