Cloud point, pour point and filterability of diesel and heating fuels are improved by the incorporation of minor amounts of an additive prepared from the reaction products of a long chain oligomeric alkylsuccinic anhydride, a higher alkyl linear saturated alcohol and a tertiary amino substituted polyol.

Low temperature fluidity improver and compositions thereof

A product of reaction suitable for use as a lubricant additive made by reacting a preformed Mannich base with a reactive hydrocarbyl amine, thiol or dithiophosphoric acid having at least one reactive hydrogen.

Phenolic-containing Mannich base reaction products and lubricant

The incorporation of minor amounts of an additive prepared from the reaction products of a long chain oligomeric alkylsuccinic anhydride or the corresponding acid, a mono or polyfunctional epoxide and a long chain secondary amine provide improved cloud point, pour point and filterability for diesel and heating fuels.

Low temperature fluidity improver

Heavy metal salts of certain branched chain carboxylic acids significantly improve the filterability, pour point and cloud point of liquid hydrocarbyl fuels when incorporated therein.

Fuel compositions having improved low temperature characteristics

The product of reaction between a branched chain monocarboxylic acid amide, an epoxide and a carboxylic acid when added to a hydrocarbyl distillate fuel in minor effective amounts provides a fuel composition having improved cold flowability.

Cold flow improving fuel additive compound and fuel composition

A reaction product or additive compound comprising an ester derivative of a branched chain monocarboxylic acid, wherein said ester derivative has at least one tertiary amine group and at least one ester group. The additive compound when added to a hydrocarbyl distillate fuel in a cold flow improving effective amount produces a fuel composition having improved cold flowability.

Cold flow improving additive compound and fuel composition containing

The product of reaction between an ester derivative of a branched chain monocarboxylic acid, having at least one tertiary amine group, an epoxide and an additional carboxylic acid when added to a hydrocarbyl distillate fuel in minor effective amounts provides a fuel composition having improved cold flowability.

A telomeric acid, a tertiary amine, and an epoxide are reacted in the absence of added water. The product recovered is effective in improving the filterability and reducing the pour point of diesel fuel. Alternatively the product can be prepared by reacting a quaternary ammonium hydroxide and a telomeric acid.

Additives for improving low temperature characteristics of fuels and

Compounds comprising ether capped alcohols, particularly alkoxy polyalkylene glycols with organic acids are highly effective demulsifier additives when incorporated into various liquid hydrocarbyl lubricant media.
