摘要:
The invention relates to a method of reducing the inhalation toxicity of functional fluids by incorporating into a functional fluid an effective amount of copolymer which is obtainable by copolymerizing etheylene oxide, propylene oxide and/or butylenes oxide with an initiator monool or diol, said copolymer having a degree of unsaturation of less than about 0.01 meq/g.

摘要:
The present invention relates to novel fuel additives obtainable by reacting carboxylic acids and alkanol amines under specific conditions. Said additives show an improved performance in fuels, like gasoline. The invention also relates to methods of preparing the same; additive packages containing said additives; and methods of improving the storage stability of additive packages comprising a detergent additive in an organic solvent.

摘要:
A composition and method of improving the fuel economy of hydrocarbon fuel-powdered internal combustion engines. The composition contains a propoxylated and/or butoxylated reaction product of (a) at least one fatty acid, fatty acid ester, or mixture thereof and (b) a dialkanolamime. The composition is added to a hydrocarbon fuel in an amount of about 5 to about 2,000 ppm, based on the weight of the hydrocarbon fuel, to reduce friction within the engine and achieve an enhanced fuel economy.

This invention relates to a process of producing compounds, which are useful as bleach boosters, as well as to the compounds, which are obtainable using said process, and to their use.
摘要:
The invention relates to a mixture comprising a surfactant and a cosurfactant, the cosurfactant being an amphiphilic polymer having one or more hydrophobic subunits (A) and one or more hydrophilic subunits (B), wherein one or more hydrophobic subunits (A) have been formed on the basis of a polyisobutene block whose polyisobutene macromolecules have terminal double bonds to an extent of at least 50 mol %.
摘要:
A quaternized copolymer obtainable by: (A) copolymerization of straight-chain, branched or cyclic, ethylenically unsaturated C2 to C100 hydrocarbons, which may bear oxygen- or nitrogen-functional substituents which cannot be reacted with amines to give amides or imides or with alcohols to give esters, with ethylenically unsaturated C3- to C12-mono- or dicarboxylic acids or acid derivatives, which can be reacted with amines to give amides or imides or with alcohols to give esters, to give a copolymer with a number-average molecular weight of 500 to 20 000; (B) partial or full amidation or imidation or esterification of the carboxylic acid functions by reacting them with oligoamines having 2 to 6 nitrogen atoms or alcoholamines, each of which comprises primary or secondary nitrogen atom or a hydroxyl group and a quaternizable tertiary nitrogen atom; (C) partial or full quaternization of the tertiary nitrogen atom with a quaternizing agent. The quaternized copolymer thus prepared is suitable as a fuel additive in direct-injection diesel engines.
