Fund Project:

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 constitution 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 infra-red spectrum of glycollic acid loaded organic phase.
- complexing extraction,
- glycollic acid,
- trioctylamine
