A biodegradable lubricating oil composition especially useful as a gear oil employs a synthetic alcohol ester basestock formed from mono- and dipentaerythritol with certain mono- and dicarboxylic acids or dicarboxylic acid anhydrides and an effective amount of a polyoxyalkylene alcohol demulsifying agent, a combination of alkylated organic acid and ashless succinimide rust inhibitors and an ashless dithiocarbamate antiwear and extreme pressure agent.

Biodegradable non-toxic gear oil

The incorporation of the heterocyclic saccharin functionality into the alkenylsuccinimide dispersant structures via the Mannich alkylaminoalkylation procedure provides a class of ashless non-phosphorus dispersants with multifunctional antiwear, antioxidant and corrosion inhibiting properties in lubricant compositions.

Multifunctional ashless dispersants

The reaction products of (1) anhydrides and/or poly-acids and (2) aminoalcohols or aminoalcohols/amides with long chain hydrocarbyl groups attached improve the low-temperature properties of distillate fuel when added thereto.

Additives which improve the low-temperature properties of distillate fuels are oligomeric/polymeric reaction products of anhydrides and long-chain epoxides (or their corresponding acid/diol equivalents) consisting of hydroxyl promoted polyesters and ester promoted polyesters.

Additives which improve the low-temperature properties of distillate fuels are the oligomeric/polymeric reaction products of anhydrides and one or more of the following long-chain diols: aminodiols, diaminodiols, amidodiols, with optional termonomers.

Additives which improve the low-temperature properties of distillate fuels are oligomeric/polymeric reaction products consisting of cross-linked anhydride and cross-linked epoxide (or their corresponding acid/diol equivalents), with optional termonomers.

Additives which improve the low-temperature properties of distillate fuels are the polymeric and/or oligomeric monomers selected from ester/urethane reaction products of a combination of anhydrides and epoxides (or their corresponding acid/diol equivalents), and a urethane precursor and optionally with various suitable reactive materials to provide optional termonomers.

A fuel additive is the reaction product of an intermediate reaction product of a hydrocarbon-substituted succinic anhydride and an aminosalicylic acid, preferably a 4-aminosalicylic acid. The intermediate is reacted with an aldehyde, preferably formaldehyde and an alkylenepolyamine preferably tetraethylenepentamine. The reaction product is post reacted with a hydrocarbon-substituted succinic anhydride which can be the same or different as the hydrocarbon-substituted succinic anhydride of the intermediate. The additive has dispersant and detergent properties and is effective in liquid hydrocarbon or liquid oxygenated fuels or mixtures of the said fuels.
