乙醇酸稀溶液的络合萃取

摘要/Abstract

摘要： 乙醇酸主要用作羊毛和尼龙的助染剂、锅炉和热交换器的除垢剂以及牛奶棚和食品生产设备的清洗剂,亦可用作制造乙醇酸薄荷酯.乙醇酸奎宁酯的原料及酒石酸的代用品.在现有的生产工艺中,产物乙醇酸的提取一般采用甲醇酯化水解法,工艺路线长,甲醇损耗量大,生产环境差.

Abstract: Using the extraction system consisting of trioctylamine and 1-octanal,the complexing extraction of glycollic acid from dilute solution was studied,the effects of temperature and extractant concentration on the distribution coefficient were discussed,and the con-stitution of complex and thermal effect(-△H)of extraction were determined.In addition, that two bonding types took part in the process of Lewis acid-base complexing extraction were confirmed further through analyzing the infrared spectrum of glycollic acid loaded organic phase.

Key words: complexing extraction, glycollic acid, trioctylamine
