Abstract
The invention discloses a kind of olefin hydroformylation catalyst, the catalyst includes following raw material：Three sodium sulfonates of trityl phosphine, rhodium, bidentate phosphite ester.The catalyst of the present invention has high-temperature stability, can effectively improve the reaction efficiency of olefin hydroformylation.
Description
Technical field
The present invention relates to the technical field of catalyst.
Background technology
Hydroformylation of olefin is that olefine reaction is obtained into the main method of the products such as aldehydes, in the prior art for this
The catalyst of one reaction is less efficient, and course of reaction control is difficult, catalyst poor high temperature stability.
The content of the invention
It is an object of the invention to propose that one kind has high-temperature stability, catalytic efficiency can be effectively improved, strengthens reaction control
The olefin hydroformylation catalyst of system.
Technical scheme is as follows：
A kind of olefin hydroformylation catalyst, it includes following raw material：Three sodium sulfonates of trityl phosphine, rhodium, bidentate phosphorous
Acid esters.
Preferably：The catalyst includes following raw material by part of the amount of material：1 ~ 3 part of trityl phosphine, three sulfonic acid
Sodium, 0.01 ~ 0.05 part of rhodium, 1 ~ 3 part of bidentate phosphite ester.
It is also preferred that：The catalyst includes following raw material by part of the amount of material：2 parts of trityl phosphines, three sulphurs
Sour sodium, 0.03 part of rhodium, 2 parts of bidentate phosphite esters.
The olefin hydroformylation catalyst of the present invention can effectively improve the efficiency of hydroformylation of olefin, improve product
Purity and yield, significantly reduce side reaction, strengthen the control to course of reaction.
