Problems solved by technology
The invention relates to a method of producing 3,4-epoxy-1-butylene and mainly solves the problem that a method in the prior art is low in raw material conversion rate, is serious in waste and is low in production yield. The synthetic method includes the following steps: a) performing a reaction to isopropyl benzene and air to obtain a hydrogen peroxide isopropyl benzene oxidized liquid; b) controlling the weight percentage ratio of organic acid to be not more than 0.3%, the weight percentage ratio of alkali metal ions or alkali earth metal ions to be not more than 0.1% and the weight percentage ratio of water to be not more than 0.5% in the hydrogen peroxide isopropyl benzene oxidized liquid; c) performing an epoxidation reaction to the hydrogen peroxide isopropyl benzene oxidized liquid with 1,3-butadiene to generate the 3,4-epoxy-1-butylene and [alpha],[alpha]-dimethyl benzyl alcohol; and d) performing a reaction between the [alpha],[alpha]-dimethyl benzyl alcohol and hydrogen to generate isopropyl benzene, and feeding the isopropyl benzene back to the step a) as the raw material for producing the hydrogen peroxide isopropyl benzene. The method can solves technical problems and can be used in industrial production of the 3,4-epoxy-1-butylene.
