METHOD FOR IMPROVING FLUOROCARBON ELASTOMER SEAL COMPATIBILITY
Disclosed is a method for improving compatibility of a fluorocarbon elastomer seal with a lubricating oil composition containing (a) a major amount of a base oil of lubricating viscosity; and (b) one or more dispersants containing one or more basic nitrogen atoms. The method involves adding to the lubricating oil composition an effective amount of one or more fluorocarbon elastomer compatibility improving agents of the general formula Si-X4 or a hydrolysis product thereof, wherein each X is independently a hydroxyl-containing group, hydrocarbyloxy-containing group, acyloxy-containing group, amino-containing group, monoalkyl amino-containing group or dialkyl amino-containing group.
An overbased salt of an oligomerized alkylhydroxyaromatic compound for use in a lubricating oil composition is disclosed, wherein the alkyl group of the alkylhydroxyaromatic compound is derived from an olefin mixture comprising propylene oligomers having an initial boiling point of at least about 195°C and a final boiling point of greater than 325°C and up to about 400°C as measured by ASTM D86. Also disclosed is a propylene oligomer having an initial boiling point of at least about 195°C and a final boiling point of greater than 325°C and up to about 400°C as measured by ASTM D8, wherein the propylene oligomer contains a distribution of carbon atoms that comprise at least about 50 weight percent of C14 to C20 carbon atoms.
The present invention is directed to an isomerized alpha olefin sulfonate and a method of making the same wherein the isomerized alpha olefin sulfonate is derived from sulfonating an isomerized alpha olefin with sulfur trioxide in the presence of air thereby producing an isomerized alpha olefin sulfonic acid, wherein the isomerized alpha olefin is derived from the isomerization of C12-C20 normal alpha olefins; and neutralizing the isomerized alpha olefin sulfonic acid with a source of an alkali metal or ammonium or substituted ammonium ion.
Disclosed is a method for preparing a hydroxyl functionalized polymer from a Lewis acid promoted carbonyl-ene reaction comprising: selecting a vinylidene terminated polyolefin having a number average molecular weight from about 950 to about 5000 and having a terminal vinylidene content greater than 50 mole percent; selecting a carbonyl enophile; selecting a Lewis acid; and contacting the components in step a), b) and c) under reactive conditions to form the hydroxyl functionalized polymer.

LOW TEMPERATURE PERFORMANCE LUBRICATING OIL DETERGENTS AND METHOD OF MAKING THE SAME
A carboxylate detergent prepared by the process comprising (a) alkylating a hydroxyaromatic compound with at least one alpha olefin oligomer, derived from C8 to C20 alpha olefins, to thereby produce an alkylhydroxyaromatic compound, and wherein at least 90 % of the molecules in the alkylhydroxyaromatic compound have the alkyl group attached at the 4-position or higher from the terminus of the longest chain of the alkyl group, and and further wherein the alkyl group comprises at least one hydrocarbon tail of at least 7 carbons; (b) neutralizing the resulting alkylated hydroxyaromatic compound with an alkali metal base; (c) carbonating the alkali metal salt from step (b) with carbon dioxide; (d) acidifying the salt produced in step (c); and (e) overbasing the resulting alkylated hydroxyaromatic carboxylic acid.
An overbased, sulfurized salt of at least one alkylated hydroxyaromatic compound, wherein the alkyl substituent of the hydroxyaromatic compound is a residue of at least one isomerized olefin having from about 15 to about 99 wt. % branching is disclosed. The overbased, sulfurized salt of at least one alkylated hydroxyaromatic compound is produced by the process comprising: (a) alkylating at least one hydroxyaromatic compound with at least one isomerized olefin having from about 15 to about 99 wt. % branching obtained by isomerizing at least one normal alpha olefin having from about 10 to about 40 carbon atoms, to provide at least one alkylated hydroxyaromatic compound; (b) neutralizing and sulfurizing the alkylated hydroxyaromatic compound in any order to provide at least one neutralized, sulfurized alkylated hydroxyaromatic compound; and (c) overbasing the at least one neutralized, sulfurized alkylated hydroxyaromatic compound.
