亚氨基二乙腈制备亚氨基二乙酸及其母液处理条件的研究

Study on Production of Iminodiacetic Acid from Iminodiacetonitrile and Treatment Conditions of Mother Liquor

以亚氨基二乙腈为原料,经碱解、酸化后提取亚氨基二乙酸,研究母液浓缩分离除盐的条件。通过处理,减少废水排放,提高反应收率。

Iminodiacetic acid was produced with alkaline hydrolysis and acidification applied iminodiacetonitrile as material. The conditions for concentration, separation and desalting of mother liquor were investigated. After treatment, the wastewater drainage reduced and the reaction yield increased.
