Abstract
A process for the production of polyisobutylene (PIB) from isobutene-containing feed comprises contacting said feed with a catalyst composition comprising halides of a metal component anchored on an adsorbent inorganic oxide solid by an oxygen-metal bond to provide a reaction mixture containing said polyisobutylene; and thereafter separating and recovering said polyisobutylene.
Claims19
A process for the production of polyisobutylene (PIB) which comprises:
- contacting isobutene-containing feed, under heterogeneous oligomerization conditions with a catalyst composition comprising halides of a metal component anchored on a solid adsorbent inorganic oxide support by an oxygen-metal bond and a promoter selected from the group consisting of water, alkanol, alkyl halide and HCl, to provide a reaction mixture containing said polyisobutene, wherein said inorganic oxide support has a pore size of 50 to 400 angstroms;
- and separating and recovering said polyisobutene.
A process for the production of polyisobutylene (PIB) which consists essentially, of:
- contacting isobutene-containing feed, under heterogeneous oligomerization conditions with a catalyst composition comprising halides of a metal component anchored on a solid adsorbent inorganic oxide support by an oxygen-metal bond and a promoter selected from the group consisting of water, alkanol, alkyl halide and HCl, to provide a reaction mixture containing said polyisobutene, wherein said inorganic oxide support has a pore size of 40 to 400 angstroms;
- and separating and recovering said polyisobutene by filtration.
