摘要
针对大学化学三组分体系液-液平衡相图测绘实验中乙酸正丁酯腐蚀滴定管聚四氟乙烯旋塞问题进行了实验方法改进,将原来的体积量取法更改为体积量取与质量量取相配合的实验操作方法。并在此基础上,考察了几种新的绿色化实验体系——醋酸丙酯/正己醇/醋酸异丙酯-乙醇-水体系在该实验中的操作可行性,最后对它们的实验效果进行了比较。
In this paper,an experimental method was developed to improve the test method of n-butyl acetate etch in the chemical three-component system liquid-iiquid equilibrium phase graphing experiment.The improvement was that the original volume measurement was changed into the experimental operation method of volume measuring matched with the mass measuring. Based on that method,the feasibility of several new green experiment systems,n-propyl acetate/ n-hexanol/isopropyl acetate-ethanol-water systems in this experiment were investigated,and their experimental results were compared at last.
