Abstract
A process for preparing 4-methyl-1-pentene comprising dimerizing propylene in the presence of a catalyst, characterized in that the catalyst is composed of sodium and/or sodium amide supported on a carrier represented by the following formula K.sub.2 O.xAl.sub.2 O.sub.3 wherein x has a value in the range of 0.5.ltoreq..times..ltoreq.11. In one embodiment, the catalyst is hydrogenated prior to the use thereof.
Claims6
A process for the preparation of 4-methyl-1-pentene which consists of dimerizing propylene at a temperature of 100.degree. C.-250.degree. C. in the presence of a catalyst consisting of at least one compound selected from the group consisting of sodium and sodium amide supported on a carrier of formula
- K.sub.2 O.xAl.sub.2 O.sub.3
- wherein x has a value in the range of 0.5.ltoreq.x.ltoreq.11, said carrier being prepared by heating at 400.degree.-2000.degree. C., a mixture of K.sub.2 O or a compound capable of forming K.sub.2 O and Al.sub.2 O.sub.3 or a compound capable of forming Al.sub.2 O.sub.3 at said temperature of 400.degree.-2000.degree. C.
