  • Patent number: 7405185
    Abstract: 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.

  • Patent number: 7256161
    Abstract: This invention is directed to a novel process for making Group II metal carbonated, overbased Mannich condensation products of alkylphenols, which process uses ethylene carbonate as both a source of carbon dioxide and ethylene glycol. In particular, under the reaction conditions using ethylene carbonate in the present invention, carbonation and overbasing Mannich condensation products of alkylphenols is possible while at the same time the viscosity of the carbonated, overbased Mannich condensation products of alkylphenols remains within acceptable levels, typically under 1000 cSt at 100° C. The present invention is also directed to carbonation of Mannich condensation products of alkylphenols using a C2-C6 alkaline glycol and carbon dioxide.

  • Patent number: 5780398
    Abstract: 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.
