摘要:
The present invention relates to the use of amines and/or Mannich adducts as detergents and/or dispersants in fuel and lubricant compositions for direct-injection gasoline engines. The invention further relates to fuel and lubricant compositions which comprise at least one such Mannich adduct, and also a bisaminoalkylated Mannich adduct.
摘要:
An apparatus for producing polyethylene glycol dinitrate. The apparatus includes providing continuously an acid composition and a glycol composition to a reaction apparatus; reacting the acid composition and the glycol composition in the reaction apparatus in a continuous manner to generate a reaction composition; using an alkaline composition to at least partially neutralize the reaction composition to cause at least a portion of the polyethylene glycol dinitrate to deposit from a solution of the reaction composition; and extracting the deposit of polyethylene glycol dinitrate.
摘要:
A method for preventing biodeterioration of fuel. The method reduces the microbial growth in fuel by administering an antimicrobial peptide (or efflux pump inhibitor) to a fuel phase of the fuel, an aqueous phase of the fuel, or both, which disrupts the cellular membrane (or the efflux pumps thereof) of microbes comprising the growth.
摘要:
A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
摘要:
This invention relates to a lubricating oil composition and production thereof. The lubricating oil composition comprises a Mannich base represented by the following formula (III) (wherein A and R2 are as defined in the specification) and a lubricant base oil. The lubricating oil composition according to this invention exhibits excellent cleansing and dispersing performance and excellent anticorrosion performance.
摘要:
This invention relates to a Mannich base, production and use thereof in producing a detergent. The Mannich base is represented by the following formula (III), wherein A and R2 are as defined in the specification. The Mannich base can be used to produce a detergent and a fuel oil composition exhibiting excellent deposit formation suppressing performance and excellent anticorrosion performance.
摘要:
A fuel soluble additive for a diesel engine, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for a diesel engine. The fuel soluble additive includes a quaternary ammonium salt derived from the reaction of (a) a hydrocarbyl amine containing at least one tertiary amino group, (b) an epoxide compound selected from a glycidol, a glycidyl ether, glycidyl ester, polyglycidyl ether, a polyglycidyl ester, and combinations thereof, wherein substituents of the glycidyl group have, on average, less than five carbon atoms per hetero atom, and (c) optionally a proton donor.
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.
摘要:
A compound useful for reducing fouling in a hydrocarbon refining process is provided. A method for preparing the compound includes functionalizing a polymer having a vinyl chain end to obtain a terminal group having one or more anhydride units, and reacting the anhydride units with a polyamine. Methods of using the compound and compositions thereof are also provided.
摘要:
A method of removing deposits from a diesel engine, the method comprising combusting in the engine a diesel fuel composition comprising an engine cleaning additive, wherein the engine cleaning additive is the product of a Mannich reaction between: (a) an aldehyde; (b) ammonia, hydrazine or an amine; and (c) an optionally substituted phenol; wherein the or each substituent of the phenol component (c) has an average molecular weight of less than 400.
