摘要:

对2,6-二氯苯胺的生产工艺路线进行了比较,提出以苯胺和尿素为起始原料,经缩合,得二苯脲;二苯脲经磺化、氯化、水解脱碳酰基、再水解脱磺酸基,得2,6-二氯苯胺,总收率60%,其纯度达99%以上.与传统工艺相比,2,6-二氯苯胺合成成本大幅下降.

Abstract:

The production process route of 2,6-dichloroaniline was compared, and it was proposed that aniline and urea were used as starting materials and condensed to obtain diphenylurea. Diphenylurea was sulfonated, chlorinated, hydrolyzed decarboacyl group and then hydrolyzed desulfonic acid group to obtain 2,6-dichloroaniline, with a total yield of 60% and a purity of more than 99%. Compared with the traditional process, the cost of 2,6-dichloroaniline synthesis is greatly reduced.
