Title:
METHOD FOR PRODUCING ALKENE
Document Type and Number:
WIPO Patent Application WO/2023/286753
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of producing an alkene having a double bond in position 2 and having four or more carbons by means of isomerization. This method for producing an alkene having a double bond at position 2 and having four or more carbons includes a step in which an alkene having a double bond at position 1 and four or more carbons is made to undergo an isomerization reaction in the presence of a Lewis acid catalyst.
