Abstract
A synthetic oil composition comprising the reaction product of an .alpha.-olefin oligomer derived from an .alpha.-olefin monomer containing from about 6 to 20 carbon atoms and from about 0.01 to 1 mole of a phenol per mole of oligomer. The oil composition can be further reacted to form alkoxylated products and can be mixed with polar additives to form homogeneous synthetic lubricants.
Claims17
A synthetic oil which is a dispersant for polar lubricant additives comprising the alkylation reaction product of an .alpha.-olefin oligomer derived from an .alpha.-olefin monomer containing from 8 to 20 carbon atoms and prepared using a Friedel-Crafts catalyst and from about 0.01 to 1 mol of a phenol per mole of oligomer, which product has been reacted to convert at least a portion of the hydroxyl groups to alkoxylated alcohols.
A lubricant composition comprising (i) a major portion by weight of an .alpha.-olefin oligomer base oil derived from an .alpha.-olefin monomer containing from about 6 to 20 carbon atoms (ii) a minor portion by weight of at least one polar lubricant additive and (iii) a solubilizing agent for said additive, which solubilizing agent is the alkylation reaction product of an unhydrogenated .alpha.-olefin oligomer derived from an .alpha.-olefin monomer containing from 8 to 20 carbon atoms and prepared using a Friedel-Crafts catalyst and from about 0.01 to 1 mole of a phenol per mole of oligomer, which product has been reacted to convert at least a portion of the hydroxyl groups to alkoxylated alcohols.
