Olefin oligomerization.

摘要

A process for oligomerizing an olefin feedstock comprises the step of contacting the feedstock with ZSM-23 which is surface deactivated with a trialkyl pyridine compound or an organophosphite compound having an effective cross-section larger than that of the pores of ZSM-23. The resultant, substantially linear olefinic product is useful in the production of high viscosity index lubricating oils and biodegradable alkylbenzene sulfonates.
