Olefin isomerization catalyst and application thereof

Abstract

The invention discloses an olefin isomerization catalyst and an application thereof. The catalyst is an organic liquid of transition metal salt and Lewis acid, the molar ratio of which is ranged from 1: 0.5 to 1: 10. The concentration of the transition metal salt is ranged from 1 mmol / L to 10 mmol / L. The catalyst disclosed by the invention is used for liquid phase catalysis of olefin isomerization and is mild in reaction condition, relatively high in yield, easy to implement and low in cost.

Description

technical field [0001] The invention belongs to the field of organic catalysis, and more specifically relates to a catalyst and its application. Background technique [0002] The isomerization reaction of olefins refers to the reaction of isomerizing olefins with a single structure into their isomers. The isomerization reaction of olefins has a wide range of applications in the olefins preparation industry, such as the preparation of raw materials for the flavor and fragrance industry and the stereoscopic rearrangement of carbon chains (Synlett 2014, 25, 417-422). At the same time, the isomerization of olefins into internal olefins is also an important reaction in the refining industry. The isomerization of long-chain olefins into internal olefins can be used as a precursor for materials used in lubrication. Isoalkenes such as isobutene and isobutylene are important basic organic raw materials. Isobutene is mainly used in the production of gasoline additives, methyl tert-bu...
