摘要:
应用间歇减压精馏对热敏性、高沸点、高凝固点的有机物--反式-1,2-环己二醇进行分离、提纯,通过采用变压强、变回流比的方法,优化出了最佳的操作工艺条件.操作条件是:塔顶用温度为96℃左右的热水作冷凝介质;全回流开工时间2 h;控制釜温180~185℃,分段恒真空度0.086~0.092 MPa;分段恒回流比5→8→12.在此操作条件下所得产品的收率在87%以上,产品纯度可达98%以上,色泽较白.
Abstract:
Batch vacuum rectification was used to separate and purify the heat-sensitive, high boiling point and high freezing point organic matter trans-1,2-cyclohexanediol, and the optimal operating process conditions were optimized by using the method of variable pressure strength and variable reflux ratio. The operating conditions are: hot water with a temperature of about 96 °C is used as the condensing medium at the top of the tower; Full reflux start time: 2 h; Control kettle temperature 180~185°C, segmented constant vacuum 0.086~0.092 MPa; The segmented constant reflux ratio is 5→8→12. The yield of the product obtained under this operating condition is more than 87%, the purity of the product can reach more than 98%, and the color is white.
