采用IDA工艺生产草甘膦是国内众多厂家首选,经由亚氨基二乙腈碱解→二乙酸缩合至双甘膦,各家工艺条件大同小异、区别不大,而经双甘瞵生产草甘膦的合成方法则变化较大,经大家多年努力研究,反复生产实践,使草甘膦生产的各项技术指示达到了新的高度,笔者有幸在近6~7年时间内,参与了下述三种草甘膦合成方法的实验研究和生产实践,现浅述如下,供相关企业在调整工艺时参考。
Production of glyphosate using IDA process is the first choice of many domestic manufacturers, through the hydrolysis of iminodiacetonitrile → diacetic acid condensation to the PMIDA, various process conditions are similar, little difference, and the production of glyphosate by double Glycyrrhiza The method then changes a lot. After years of hard research and repeated production practices, the various technical instructions for the production of glyphosate have reached a new height. I was fortunate to have participated in the following three kinds of grass Experimental research and production practices of the synthesis of glyphosate are as follows, for the relevant enterprises in the process of adjusting the reference.
