课题：丙酮 - 甲醇的分离. 汇报人：赵善芳 日期： 2011.10.29. 目前 研究 进展及课题思路. 两种分离方法比较. 一、萃取精馏 1. 以水作为萃取剂，分离效果较好、溶剂价廉易得、无毒、溶剂后处理相对简单。 2. 以单乙醇胺为萃取剂，所需塔板数、溶剂质量比、回流比都用水做萃取剂合适。 二、变压精馏 1. 高压时低沸点物发生转换，所以常压塔和高压塔联立. 课题新思路 — 减压精馏.

  1. 课题：丙酮-甲醇的分离 汇报人：赵善芳 日期：2011.10.29

  2. 目前研究进展及课题思路

  3. 两种分离方法比较 • 一、萃取精馏 • 1.以水作为萃取剂，分离效果较好、溶剂价廉易得、无毒、溶剂后处理相对简单。 • 2.以单乙醇胺为萃取剂，所需塔板数、溶剂质量比、回流比都用水做萃取剂合适。 • 二、变压精馏 • 1.高压时低沸点物发生转换，所以常压塔和高压塔联立

  4. 课题新思路—减压精馏
