摘 要:针对当前2,4-二氯甲苯生产装置中存在的主要工艺问题,通过改进氯化合成工艺,采用先进的精馏技术,使氯化反应收率达到78%,氯气利用率达到94%,系统蒸汽消耗和电耗明显下降,从而有效地降低了生产成本,减轻了设备腐蚀和环境污染,经济效益和社会效益显著,具有很好的推广应用前景。According to the main problem of current synthesis process of 2,4 - dichlorotoluene, through improving chlorinated synthesis process,using advanced rectification technology, the reaction yield of chlorine is raised to 78%, and the utilization ratio of chlorine is now raised to 94%, the system consumption of steam and electricity is also reduced. Therefore, production cost is cut down, corrosion and pollution is minimized. All this indicates that the improvement is of remarkable economic and social benefits with prospects of being applied extensively.
