液—液三组分相图实验的绿色化研究

Study on green chemistry for a liquid-liquid ternary phase diagram

通过对有一对部分互溶的绿色液—液三组分体系—环己烷—乙醇—水、乙酸乙酯—乙醇—水、乙酸正丁酯—乙醇—水等体系平衡相图实验的反复研究,得出了(相对)最好的绿色体系。此实验体系已在06级学生实验中应用,取得了很好的实验效果。同时该绿色体系还可以在实验教学中向学生渗透绿色化学的思想理念。

By repeated studying on the equilibrium phase diagram experiment, which contained a pair of partially miscible green liquid - liquid three phase component systems - eyclohexane - ethanol - water. acetic ether - ethanol - water, n - butyl acetate - ethanol - water, etc, we got the best （ relatively） green system. This system has been applied in 2006 grade students＇ experiments and achieved excellent results. This green system can also permeate the concepts of green chemistry to the students during the experiment teaching.
