A PROCESS FOR THE ISOMERIZATION OF A VINYLIDENE OLEFIN |
摘要 |
A process for the double bond isomerization of a vinylidene olefin, comprising contacting a feed comprising the vinylidene olefin with an isomerization catalyst which comprises a molecular sieve in an acidic form, which molecular sieve comprises pores which have a pore size of more than 0.6 nm; and a process for treating an olefin mixture which comprises a linear alpha-olefin and a vinylidene olefin which is isomeric to the linear alpha-olefin and which is of the general formula CH<SUB>2</SUB>-C(R<SUP>1</SUP>)R<SUP>2</SUP>, wherein R<SUP>1 </SUP>represents an ethyl group and R<SUP>2 </SUP>represents a linear 1-alkyl group, which process comprises isomerizing the vinylidene olefin to form a double bond isomer of the vinylidene olefin by contacting a feed comprising the olefin mixture with an isomerization catalyst which comprises a molecular sieve in an acidic form, which molecular sieve comprises pores which have a pore size of more than 0.6 nm, and separating the linear alpha-olefin from the double bond isomer of the vinylidene olefin. |
