摘　　要：烧碱作为甘氨酸法生产草甘膦的主要原材料,主要用作调节酸碱的作用,最终反应生产氯化钠,氯化钠电解制得烧碱循环用于草甘膦生产,这是通常的草甘膦生产钠离子循环利用工艺。但是离子膜电解法生产烧碱工艺投资大,能耗高,而且对氯化钠的质量要求高,对于一般企业难以形成循环利用产业链。本文以江西金龙化工有限公司生产草甘膦为例,提出一种草甘膦生产中碱的循环利用的新工艺。As the main raw material for the production of glyphosate by the Glycine process,caustic soda is mainly used to regulate the role of acids and alkali.The final reaction produces sodium chloride,and sodium chloride is electrolyzed to produce caustic soda for the production of glyphosate.This is the usual glyphosate production.Sodium ion recycling process.However,the ion membrane method has a large investment in caustic soda production,High energy consumption,and high quality requirements for sodium chloride.It is difficult for general company to form a recycling industrial chain.Taking glyphosate production in Jiangxi Jinlong Chemical Co.Ltd.as an example,this paper proposes a new process of recycling alkali in Glyphosate production.
