ABSTRACT:
A process for producing substantially linear hydrocarbons by oligomerizing a lower olefin at elevated temperature and pressure which comprises contacting the lower olefin under oligomerization/polymerization conditions with siliceous acidic ZSM-23 zeolite having Bronsted acid activity; wherein the zeolite has acidic pore activity and wherein the zeolite surface is rendered substantially inactive for acidic reactions. The zeolite surface can be neutralized by a bulky pyridine compound having an effective cross-section larger than the zeolite pore. The preferred deactivating agent is 2,4,6-collidine, which may be applied to the zeolite as a pretreatment or added with olefin feed in a continuous process. The olefin oligomers may be used as alkylating agents to prepare biodegradable alkylbenzenes and alkylphenylsulfonates. A preferred catalyst for this alkylation reaction is dealuminized mordenite.
