Title:
METHOD FOR ISOMERIZING CIS-OLEFIN INTO TRANS-OLEFIN
Document Type and Number:
WIPO Patent Application WO/2022/028176
Kind Code:
A1
Abstract:
A method for isomerizing cis-olefin into trans-olefin, comprising: adding a palladium/copper compound catalyst and cis-olefin to a reaction vessel, adding an organic solvent, mixing well, and reacting in a hydrogen atmosphere to obtain trans-olefin. In the palladium/copper compound catalyst, palladium is dispersed on the surface of a copper compound in an atomic scale, H2 is induced by means of a special interface formed between Pd and a carrier to dissociate in a heterogeneous cracking mode, such that a C=C double bond is reversed, and cis-olefin is converted into trans-olefin instead of further hydrogenating the cis-olefin into alkane. The palladium/copper compound catalyst has high selectivity on the trans-olefin. The method is simple in operation process, can achieve large-scale preparation, does not need to add various additives in a catalytic process, reduces the complexity degree of a reaction system, facilitates separation and purification of products, saves the cost, and has a high industrial application value.
