Abstract

The invention discloses a butanol and butyl acetate separation method. According to the method, an extraction agent is added; an extraction rectification method is used for separating a butanol and butyl acetate mixture; the relative volatility degree of the butanol and the butyl acetate can be changed through the extraction agent; great change occurs, so that the butanol and butyl acetate can be more easily separated; butanol and butyl acetate with higher purity can be obtained; meanwhile, the added extraction agent can be effectively recovered; the cyclic utilization is realized.

Description

technical field [0001] The invention belongs to the technical field of chemical separation, and in particular relates to a method for separating butanol and butyl acetate. Background technique [0002] Butyl acetate, molecular formula C 6 h 12 o 2 , is an excellent organic solvent, widely used as a solvent for nitric acid spray paint, collodion, enamel, celluloid, rubber, artificial leather, artificial pearls, linoleum products and various resins. It is also used in industries such as safety glass, textile printing, penicillin refining, fluorescent lamp interior paint, aircraft paint, spices, medicine, etc., and of course it can also be used as an extractant. The common butyl acetate often contains impurities such as acetic acid and butanol, among which butanol and butyl acetate can form an azeotrope, which brings a lot of inconvenience to the subsequent separation. Therefore, developing new and efficient means to separate the two has become the direction of our efforts...
