Patent number: 7405185Abstract: The present invention is directed to a novel process for making Group II metal overbased sulfurized alkylphenols, which process uses alkylene carbonate as both a source of carbon dioxide and alkylene glycol. In particular, under the reaction conditions using ethylene carbonate, carbonation time is reduced to about one quarter the time taught in the prior art to make Group II metal overbased sulfurized alkylphenol compositions. The present invention is also directed to a detergent-dispersant additive composition comprising a Group II metal overbased sulfurized alkylphenols, wherein the Group II metal overbased sulfurized alkylphenols have a reduced color as measured by ASTM Test No. D 6045 and an increased hydrolytic stability as measured by a modified ASTM Test No. 2619.Type: GrantFiled: September 26, 2003Date of Patent: July 29, 2008Assignee: Chevron Oronite Company LLCInventors: Robert H.

Patent number: 5780398Abstract: An additive useful in a marine lubricating oil is produced by reacting at elevated temperatures in the presence of at least one light hydrocarbon solvent and promoter: an alkyl oxy aromatic sulfonate; an alkaline earth metal base; carbon dioxide; and an acid component, such as carboxylic acid, an acid anhydride, an acid choride, or ester thereof. If the alkyl oxy aromatic sulfonate is in the acidic form, then the acid component is in the acidic form. If the alkyl oxy aromatic sulfonate is in the neutralized form, then the acid component is in the neutralized form. If the alkyl oxy aromatic sulfonate is in the overbased form, then the acid component is either in the acidic form or in the neutralized form.Type: GrantFiled: July 24, 1997Date of Patent: July 14, 1998Assignee: Chevron Chemical CompanyInventors: William F. King, Richard J. Nelson, Robert H. Wollenberg, Steven G. Lockett
