Abstract

The invention provides a purification method of tert-butyl hydroperoxide. Compared with the prior art, the method disclosed by the invention has the following advantages that an azeotropic distillation method is adopted to purify a tert-butyl hydroperoxide / tert-butyl alcohol mixed system containing water and other impurities. Azeotropic distillation operation conditions are mild, safety is high, and no extra components are introduced. After concentration and purification, further deep water removal and acid removal are performed through a molecular sieve, other impurities are not introduced, and the operation is simple.

Description

technical field

[0001] The invention belongs to the technical field of tert-butyl hydroperoxide, and in particular relates to a purification method of tert-butyl hydroperoxide. Background technique

[0002] Tert-butyl hydroperoxide (TBHP) is an important organic peroxide, currently it is mainly used as an initiator of polymerization reaction, an oxidant of olefin epoxidation reaction, an additive of refined oil and applied in the paint industry, etc. Tert-butyl hydroperoxide has a high yield and selectivity for olefin epoxidation, and the reaction of propylene oxide to propylene oxide (PO) is the most widely used in industry, such as the commercialized PO / MTBE process and PO / TBA process.

[0003] Specifically, first prepare tert-butyl hydroperoxide by isobutane oxidation method, then prepare propylene oxide through tert-butyl hydroperoxide oxidation of propylene, and co-produce by-product methyl tert-butyl ether (MTBE) as PO / MTBE method , co-production by-product tert-buta...
