| 摘 要： | 分子蒸馏是一种新型的分离技术,与传统的分离技术相比:操作温度远低于液体沸点,蒸馏压力在极高真空度下,受热时间短,系统基本绝氧,能最大限度地保证物系中的有效成分。本文分析了分子蒸馏技术的机理,介绍了目前常用的静止式、降膜式、刮膜式和离心式分子蒸馏器,以及分子蒸馏技术在化工、医药、轻工和食品行业的应用情况和发展趋势。

| Abstract: | The molecular distillation is a new kind of separation technique.Compared with the normal separation technique,the operating temperature far below the boiling point of liquid,distillation at very high pressure under vacuum,heating time is short,basic oxygen system,the useful compositions can be maximum remained.The mechanism of molecular distillation was analyzed in this paper.Stationary,falling-film,the UIC and centrifugal molecular distillatory in common use,and also the application and the development trend in chemical products,medicine,light industry and food industry of molecular distillation were introduced. |
