二苯胍合成路线

二苯胍制备

1.我国二苯胍生产工艺均为二硫化碳和苯胺缩合制得二苯硫脲，再由二苯硫脲、氧化铅、氢氧化铵与硫酸铵在40-70℃的条件下制成二苯胍的硫酸盐，经提取、过滤，中和得半成品。再经干燥、筛选即得成品促进剂D。各生产工艺的不同点主要集中在二苯硫脲合成二苯胍这一步，早期国内采用氧化铅法，由于产品质量差、操作人员的粉尘污染（铅粉尘）、母液的三废处理、收率低等问题，此方法在20世纪90年代后期基本已停止使用。此法用氧化铅作脱硫剂，用氨水作胺化剂，用硫酸铵作为二苯胍的萃取剂，在原料消耗、环境保护方面都存在问题。

改用氧化锌可改进原有的生产工艺。90年代中期，国内有氧化锌法和氧化铁法的报道，但因各种原因并未普及，已被淘汰。现在所有国内二苯胍的生产企业均采用氧气法生产，即二苯硫脲与氧气、氨水反应8h后得二苯胍。原料消耗定额：二苯硫脲1250kg/t、氧气240m3、醋酸铜（催化剂）0.86kg/t、氨水1000kg/t、水252kg/t。

2.首先把所需量的乙醇和水加入耐压反应釜，室温下通氨1h，使溶液中的氨达到饱和，然后边搅拌边加入二苯基硫脲，完毕，再通氨15min。将氧化锌调成稀糊状，慢慢滴加至反应釜中，滴加时间1h左右，最后将反应釜密封，通氨升压到所需值，在38～40℃反应3h，继续升温到一定温度再反应一定时间。反应完毕，释压、放料、过滤、醇洗。将滤液和洗液合并精馏，以回收部分乙醇。由于二苯胍仅微溶于水，随着精馏的进行，釜底析出粗二苯胍的量越来越多，待乙醇基本蒸出后停止。然后往其中加入少量水，在不断搅拌下滴加1∶1的盐酸，使二苯胍生成可溶性的二苯胍盐酸盐，待溶液pH值为2～3时，停止滴加盐酸，将其过滤除去副产物和杂质，滤液再用10%的NaOH中和，此时即有精制的白色二苯胍沉淀析出。再过滤、水洗、干燥即产品。

3.也可采用以N,N'-二苯硫脲、氨水和氧气为原料，以二价铜离子为催化剂的氧气法生产本品，合成反应式如下

首先，铜盐与氢氧化铵、氨及N,N'-二苯硫脲反应生成络合物二氨N,N'-二苯硫脲合铜（Ⅱ）氢氧化物和铵盐。然后N,N'-二苯硫脲经氧气氧化脱硫及上氨反应得到产品二苯胍和亚硫酸铵。亚硫酸铵继续被氧气氧化生成硫酸铵。
