Method For Manufacturing Ionic Liquid Catalysts

US Patent:
6984605, Jan 10, 2006
Filed:
Apr 22, 2003
Appl. No.:
10/420182
Inventors:
Kenneth D. Hope - Kingwood TX, US
Donald A. Stern - Kingwood TX, US
Donald W. Twomey - Kingwood TX, US
Assignee:
Chevron Phillips Chemical Company, LP - The Woodlands TX
International Classification:
B01J 31/00
US Classification:
502164, 502162, 502169, 502167
Abstract:
A method for manufacturing ionic liquid compositions by use of a two-step process which includes the contacting, under first reaction conditions, an amine compound with a hydrogen halide that is preferably in the gaseous form to provide a first reaction mixture. The first reaction mixture is then contacted, under second reaction conditions, with a metal halide compound to form the ionic liquid end-product.

Method For Manufacturing High Viscosity Polyalphaolefins Using Ionic Liquid Catalysts

US Patent:
7259284, Aug 21, 2007
Filed:
Jul 27, 2004
Appl. No.:
10/900221
Inventors:
Kenneth D. Hope - Kingwood TX, US
Donald W. Twomey - Kingwood TX, US
Michael S. Driver - San Francisco CA, US
Donald A. Stern - Kingwood TX, US
J. Barry Collins - New Caney TX, US
Thomas V. Harris - Benicia CA, US
Assignee:
Chevron Phillips Chemical Company, LP - The Woodlands TX
International Classification:
C07C 2/04
US Classification:
585510, 585512, 585513, 585514, 585520
Abstract:
A process for preparing very high viscosity polyalphaolefins using an acidic ionic liquid oligomerization catalyst in the absence of an organic diluent and the products formed thereby. A method of continuously manufacturing a high viscosity polyalphaolefin product by introducing a monomer and an ionic liquid catalyst together into a reaction zone while simultaneously withdrawing from the reaction zone a reaction zone effluent that contains the high viscosity polyalphaolefin. The reaction zone is operated under reaction conditions suitable for producing the high viscosity polyalphaolefin product. The preferred high viscosity polyalphaolefin has a kinematic viscosity exceeding 8 cSt and is the reaction product of the trimerization, oligomerization, or polymerization of an alpha olefin or a mixture of one or more product thereof. The high viscosity polyalphaolefins are useful as lubricants or lubricant additives.
