Abstract

The invention discloses a method for preparing tert-butyl hydrogen peroxide and tert-butyl alcohol by oxidating isobutene. Molecular oxygen is taken as an oxygen source; N-hydroxy phthalimide (NHPI) or a derivative thereof is taken as a catalyst; in the presence of a polar solvent, carrying out catalytic oxidation on the liquid phase of the isobutane to prepare the tert-butyl hydrogen peroxide and the tert-butyl alcohol; after finishing the reaction and rapidly cooling, the catalyst and the products are subjected to solid-liquid separation; and the catalyst is recycled through centrifugal sedimentation and washing. Compared with the existing process without catalytic optimization, the method disclosed by the invention has mild reaction conditions, the temperature and the pressure needed in the reaction can be remarkably lowered; and in addition, under the condition of having higher rate of conversion of the isobutane, the high selectivity of the tert-butyl hydrogen peroxide and the tert-butyl alcohol can be maintained.

Description

technical field

[0001] The present invention relates to a method for preparing tert-butyl hydroperoxide and tert-butanol by oxidation of isobutane, and more particularly relates to a method for preparing tert-butyl hydroperoxide by oxidation of isobutane using non-metal as a catalyst and molecular oxygen as an oxygen source. Method for hydrogen peroxide and tert-butanol. Background technique

[0002] Tert-butyl hydroperoxide is a main raw material and an important intermediate product in the chemical industry. It is widely used as an oxidant, an initiator of free radical reactions, and is also used as a raw material for the synthesis of other organic peroxides. A common oxygen source for oxypropane.

[0003] Because tert-butyl hydroperoxide has a wide range of applications, its synthesis research has attracted widespread attention at home and abroad. According to the existing synthetic method of industry, it is mainly divided into four classes: (1) tert-butanol hydrogen pe...
