PURPOSE: To oligomerize an olefin by bringing an olefinic feedstock into contact with ZSM-23 surface-inactivated by a trialkylpyridine or org. phosphorous acid compd. having an effective sectional area larger than that of the pores of the ZSM-23. n CONSTITUTION: The oligomer product is obtd. by bringing the olefinic feedstock (e.g.; propylene, butene) into contact with the ZSM-23 surface-inactivated by the trialkylpyridine (e.g.; 2,4,60-collidine) or the org. phosphorous acid compd. [e.g.; tris(2-ethylhexyl phosphite) having an effective sectional area larger than that of the pores of the ZSM-23. The conditions for the contact are 100 to 350°C, atm. pressure to 2000 KPa, weight time space velocity 0.01 to 2 (more preferably respectively 150 to 250°C, 1000 to 10,000 KZPa, 0.2 to 1). The oligomeric product is useful as the feedstock for lubricating oils and biodecomposable alkylbenzene sulfonates. n COPYRIGHT: (C)1989,JPO |
