摘要:
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.
摘要:
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.
摘要:
Fluid compositions containing a lubricant or liquid hydrocarbon fuel and a minor amount of a complex salt containing a 5- or 6-member ring are provided. These derivatives are made by complexing (1) the reaction product of an alcohol or an aminoalcohol with a succinic compound containing a long-chain hydrocarbon with (2) a metal salt. One such complex is one made by reacting a metal salt with the product of reaction between an alkylsuccinic acid or anhydride and said alcohol or aminoalcohol.
摘要:
Benzotriazole when reacted with unsaturated esters such as acrylate ester provides products which when added to lubricating oils improve the resistance of said oils to oxidation.
摘要:
The detergency properties of a fuel or a lubricant are improved by adding thereto a Mannich base product prepared by reacting a high molecular weight alkyl substituted hydroxyaromatic compound, a polyoxyethylene polyamine and an aldehyde.
摘要:
Lubricant compositions are provided containing a detergency improving amount of a metal complex prepared by (a) reacting a salt or oxide of a metal capable of forming a Werner complex with a compound containing at least one phenolic group to yield the metal salt of said compound; (b) reacting the resulting metal salt with a polyamine having the formula H.sub.2 N(C.sub.2 H.sub.4 NH).sub.x H where x is 1 to 5; and (c) reacting the resulting product with an alkenylsuccinic anhydride characterized by a molecular weight between about 400 and about 3,000.
