摘要:
Fuel oils and lubricants of improved properties contain ethylene-propylene copolymers bearing units derived fron N-vinyl pyrrolidone and phenothiazine.
摘要:
Diesel oil of improved storage stability contains a condensate of an alkyl polyoxyethylene polyoxypropylene amine, maleic anhydride and an N-alkyl alkylene diamine.
摘要:
A material is described having a use as a motor fuel additive for controlling engine octane requirement increase (ORI), controlling and reducing hydrocarbon and carbon monoxide engine emissions, and having carburetor detergency properties. Said material is the reaction product of maleic anhydride, a polyether polyamine, preferably a polyether diamine, and a hydrocarbyl polyamine, preferably an n-alkyl-alkylene diamine. A concentrate comprising the prescribed reaction product dissolved in a hydrocarbon solvent is also described. Motor fuels containing the reaction product additive of the instant invention show improved ORI control and carburetor detergency in comparison with motor fuels without said reaction product additive.
摘要:
Gasoline of reduced combustion chamber deposit attained by addition of, as additive, a reaction product of polyoxyisopropylenediamine-maleic anhydride-N-tallow-1,3-propane diamine.
摘要:
A keto-acid amide derived from the amination of a bicyclic keto-acid with an N-alkyl-alkylene diamine. The keto-acid amides are useful as carburetor detergents for motor fuel compositions.
摘要:
A process for converting a hazy or potentially hazy water saturated alcohol-gasoline blend into a clear, stable gasoline composition having an improved octane rating. The conversion is made by adding to and blending with the hazy gasoline, a nonionic surfactant of an aminated polyisopropoxylated polyethoxylated alkylphenol.
摘要:
A novel fuel composition contains ethanol or methanol plus, as a corrosion inhibitor, a reaction product of a secondary amine, an isatoic anhydride and a (C.sub.10 -C.sub.14 alkoxy)-n-alkyl primary amine.
摘要:
Novel condensation products of N-alkyl-alkylenediamines and isopropylidene malonate are prepared by refluxing the reactants in solvents inert to the reactants, removing this solvent and extracting the reaction system with an inert solvent such as xylene.
摘要:
Alcohols may be inhibited against corrosion by addition thereto of a reaction product of a maleic anhydride and certain amines typified by alkyl isopropoxy aminopropyl amines.
