标题:N,N-二甲基-N-苯基-(N-氟二氯甲硫基)-磺酰 胺的合成工艺
摘要:本发明公开了一种n,N-二甲基-N-苯基-(N-氟二氯甲硫基)-磺酰胺的合成工艺,该合成工艺采用氟化铁做氟化物,以氟二氯甲基硫酰氯的甲苯溶液和n,N-二甲基-N'-苯基磺酰胺在一定的反应条件下重结晶后制得n,N-二甲基-N-苯基-(N-氟二氯甲硫基)-磺酰胺.该合成工艺先合成中间体,在中间体的制备环节中能提高中间体的利用率和收率,且反应后的剩余物质便于回收利用,大大节约成本且降低环境污染,在中间体合成过程中采用氟化铁作为氟化物不仅提高了n,N-二甲基-N-苯基-(N-氟二氯甲硫基)-磺酰胺的收率,且对环境影响小,解决了现有方法原料成本高,产生的"三废"对环境危害大,收率很低且不稳定而导致n,N-二甲基-N-苯基-(N-氟二氯甲硫基)-磺酰胺难于工业化生产等问题.
