Process for producing poly-&#x3b1;-olefins are described wherein the processes comprise: (a) providing a primary alcohol; and (b) polymerizing the primary alcohol in the presence of an acidic alumino layer silicate to form a poly-&#x3b1;-olefin. Water formed during the polymerization can be removed, optionally during the polymerization, and subsequent hydrogenation may be performed.

Processes for producing poly-alpha-olefins, and poly-alpha-olefins produced thereby

Processes for preparing conjugated linoleic acid triglycerides are described which comprise: (a) providing a conjugated linoleic acid alkyl ester, wherein the alkyl group is linear or branched and has from 1 to 5 carbon atoms; and (b) subjecting conjugated linoleic acid alkyl ester to transesterification with triacetin to provide a conjugated linoleic acid triglyceride.

Processes for the production of triglycerides of conjugated linoleic acid

A process for making OH-terminated compounds involving: (a) combining at least one CH OH-terminated diol and a titanium-containing catalyst to form a reaction mixture; (b) heating the reaction mixture to a temperature of from 110 to 160&deg; C. to form a heated reaction mixture; (c) continuously adding dimethyl carbonate to the heated reaction mixture; (d) continuously distilling all methanol released from the heated reaction mixture; (e) heating the reaction mixture to a temperature of from 190 to 240&deg; C. to form an OH-terminated product; (f) removing unreleased methanol and dimethyl carbonate from the reaction mixture under a pressure of less than 100 mbar; and (g) deactivating the titanium-containing catalyst by adding from 0.8 to 2 equivalents, based on the catalyst, of a 1 to 20% by weight aqueous solution of phosphoric acid to the reaction mixture, at a temperature of from 80 to 120&deg; C.
