减少丙酮中杂质甲醇的方法

Method of reducing impurity methanol in Acetone

丙酮是优良的有机溶剂和重要的化工原料之一,其质量直接影响到下游化工产品的品质。甲醇是丙酮产品中的杂质之一,影响其质量。本文分析了工业生产中甲醇的来源,并根据生产实际情况,提出2种降低甲醇的方法。第一,在现有生产工艺的条件下,改变操作方法;第二,增加一脱甲醇塔,从而提高丙酮产品质量。

Acetone is a good organic solvent and important chemical raw material,and its quality influences on subsequent products.Methanol is one of impurity and it affects acetone’s quality.The article analyses the source of methanol and proposes two methods to decrease the content of methanol.Firstly,chang the operating method under the present conditions.Secondly,advise to add a tower to removal methanol from product to improve the acetone’s quality.
