Abstract

The invention provides a method used for preparing methylethyl ketone peroxide by taking an acidic ion exchange resin as a catalyst. According to the method, butanone and hydrogen peroxide are taken as raw materials, the acidic ion exchange resin is taken as the catalyst, dibutyl phthalate is taken as a diluent, after constant temperature stirring reaction, an obtained mixture is allowed to stand for separation, and an obtained oil phase is methylethyl ketone peroxide. According to the method, the heterogeneous catalyst is adopted, so that the catalyst and the reaction materials can be separated easily, and the catalyst can be recycled for a plurality of times; reaction is stable, the temperature is increased slowly, and reaction is continuous and stable; product active oxygen content is 13%, and economic value is high; application of strong such as sulfuric acid is avoided, so that corrosion on equipment is less, environment pollution is not caused, and environmental benefit is relatively high.

Description

technical field

[0001] The invention relates to a method for preparing methyl ethyl ketone peroxide, in particular to a method for preparing methyl ethyl ketone peroxide by using an acidic ion exchange resin as a catalyst. Background technique

[0002] Organic peroxides can be divided into hydrocarbyl peroxides, percarboxylic acids, acyl peroxides, ester peroxides, ketone peroxides, etc. according to the different functional groups of the substituents. Among them, methyl ethyl ketone peroxide (referred to as MEKP) As an important organic peroxide, it is widely used as an initiator for unsaturated olefin polymerization, a catalyst for organic reactions and a curing agent for unsaturated polyester resins. .

[0003] In the process of producing methyl ethyl ketone peroxide (referred to as MEKP), it has been prepared from butanone (referred to as MEK) and hydrogen peroxide under the catalysis of sulfuric acid and phosphoric acid at home and abroad, but the disadvantages are: st...
