Title:
TRIMERIZATION OF OLEFIN
Document Type and Number:
Japanese Patent JP2022084537
Kind Code:
A
Abstract:
To provide a method for producing olefin trimers from olefin monomers with high selectivity.SOLUTION: A method for producing olefin trimers comprises: feeding into a reactor containing a dimerization catalyst olefin monomer feed and at least one oxygen-containing moderator; operating the reactor at 40-140°C and 10-40 bar for carrying out catalytic dimerization reactions and addition reactions between olefin monomers and dimers; and distilling a reactor outlet stream to separate a bottom product containing olefin trimers, in which a lighter product is recycled into the reactor, olefin monomers are fed into the reactor, amounts of the olefin monomer feed and the recycled feed fed into the reactor are controlled such that a mass ratio of olefin monomers to olefin dimers entering the reactor is selected from a range of 1:8-1:15.SELECTED DRAWING: Figure 1
