Separation of tetrahydrofuran-ethanol binary azeotrope by extractive distillation

萃取精馏分离四氢呋喃-乙醇共沸物系

The method to separate the product was discussed finally. The n-hexane azeotrope was used to purify the triethoxysilane and a good result was got.

同时对产物的分离进行了研究，采用正己烷共沸精馏提纯三乙氧基硅烷，得到了较好的结果。

So if I have this special mixture here, of A and B, at this point here, I form what's called an azeotrope.

如果我们有这样子特殊的A和B的混合物，在这个点，我们得到了所谓的共沸混合物。

The screening indexes of extractant include relative volatility, molecular weight, freezing point, boiling point, azeotrope judgement and molecule stability.

本文提出以相对挥发度、相对分子摩尔质量、熔点、沸点、共沸和稳定判断等为筛选指标进行分子设计；

The crystal of Malachite is more in the precursors dehydrated by azeotrope distillation than by normal heating.

共沸蒸馏脱水法比加热脱水法制备的前驱体含有较多的孔雀石相。

And a negative azeotrope here.

这时就是一个负的共沸混合物。

The dry furfural can be obtained and the composition of the tops was close to the composition of furfural water azeotrope.
