摘要:
采用间歇萃取精馏分离叔丁醇水混合物,选用乙二醇为萃取剂。研究了回流比、溶剂进料流速、溶剂进料温度等对分离叔丁醇水混合物的影响。最佳操作条件为:回流比为2、溶剂进料温度为90 ℃、溶剂进料流速为5.1 g/min,在此条件下,叔丁醇质量分数可达98.41%。同时用Aspen Plus 软件对间歇萃取精馏过程进行模拟,结果表明实验结果与模拟结果基本一致。
Abstract:
Batch extractive distillation process was chosen to separate tert-butyl alcohol-water mixture and the ethylene glycol as solvent. The effect of reflux ratio, solvent feeding speed and solvent feeding temperature was analyzed. The best operating conditions were that the reflux ratio was 2, solventfeeding speed was 5.1 g/min, the solvent feeding temperature was 90 ℃. Under those conditions, the mass fraction of tert-butyl alcohol could reach 98.41%.The batch extractive distillation column was simulated by Aspen plussoftware, and an agreement was found between the predicted and the experimentaldata.
