1,6-己二醇精馏分离研究

Study on the Distillation of 1,6-Hexanediol

采用减压精馏的方法对己二酸二甲酯加氢产物1,6-己二醇分离,可以得到纯度大于99%的1,6-己二醇产品。在釜温为168～185℃、顶温为160～180℃、真空度-0.093～-0.096 Mpa、回流比为60∶2～60∶10条件下,研究了真空度和回流比对1,6-己二醇纯度的影响。

Hydrogenation of dimethyl adipate gives the product of 1,6-hexanediol,which can be obtained in purity of 99% by way of vacuum distillation.The effects of vacuum degree and reflux ratio on the purity of 1,6-hexanediol were investigated.
