Abstract

The invention provides a method for preparing tert-butyl peroxide by using a heterogeneous catalyst. The method comprises the following steps: by using tert-butyl alcohol and oxydol as raw materials and an acidic ion exchange resin as a catalyst, reacting under reflux, cooling, standing, and separating to obtain an oil phase and a water phase; and washing the oil phase with alkali and water to obtain a di-tert-butyl peroxide solution (DTBP), wherein the oil phase water washing solution and water phase are the tert-butyl hydroperoxide water solution (TBHP). Since the ion exchange resin has the advantages of large pore structure, high acidity and high catalysis efficiency and the large pore structure can not be destroyed in reaction, the catalyst can be easily separated from the reaction product and can be recycled repeatedly, thereby having higher economic value. Besides, no sulfuric acid or any other strong acid is used in the production process, so the method has the advantages of low corrosion to equipment and no environment pollution, and has higher environmental benefit.

Description

technical field

[0001] The invention relates to a method for preparing tert-butyl peroxide, in particular to a method for preparing tert-butyl peroxide with a heterogeneous 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, tert-butyl hydroperoxide ( TBHP) and di-tert-butyl peroxide (DTBP) are the main raw materials and important intermediates in the chemical industry, and are widely used as oxidants, initiators and crosslinking agents.

[0003] In the process of producing DTBP and TBHP, scholars at home and abroad have used tert-butanol (TBA) and hydrogen peroxide to prepare under the catalysis of sulfuric acid, phosphoric acid, zeolite, heteropolyacids, etc. The corrosion of equipment is serious, and the cost of waste acid treatment is very high; the catalyst is dissolve...
