摘要:
A method of compatibilization asphaltenes containing bituminous liquids which process comprises:a) reacting an asphaltene with phosphorous trichloride in the presence of a liquid to form a phosphochlorinated asphaltene containing from about 0.01 wt % to about 20 wt. % phosphorous;b) reacting the phosphochlorinated asphaltene with an equimolar amount of aliphatic or aromatic alcohols and phenols selected from the group consisting of:i) an aliphatic alcohol;ii) a naphthyl alcohol;iii) an alkyl quinizarin;iv) an oligomeric mixed polyether aliphatic terminal diol; andv) an oligomeric polyalkene terminal diol to produce a compatibilized asphaltene; andc) recovering the compatibilized asphaltene product.
摘要:
Asphaltenes isolated from bituminous products that have been bulk phosphochlorinated using phosphorous trichloride and amidated using aminoacids or aminoacid salts show enhanced dissolution properties when added to bituminous liquids or bituminous liquids blended with gasoline.
摘要:
A polymeric lubricating oil additive containing pendant perfluoroaliphatic urethane units that behaves as a VI Improver and a fuel economy enhancer when added to lubricating oil compositions. The polymeric substrate may be a copolymer of 15-85 mole % ethylene and propylene or a terpolymer of 15-85 mole % ethylene, propylene, and 20-80 mole % of a non-conjugated diene or triene (C.sub.3 -C.sub.10) alpha olefin. The copolymer or terpolymer substrate has a molecular weight range of about 5,000 to about 500,000. A graft copolymer or terpolymer containing pendant isocyanate groups is prepared by reacting the ethylene propylene co- or terpolymer with an acrylating agent. Post-reacting the copolymer or terpolymer containing the pendant isocyanate group with a perfluoroaliphatic alcohol generates the additive.
摘要:
An additive composition comprising a graft and derivatized block copolymer prepared from a styrene-ethylenebutylene-styrene characterized in that unsaturation in the styrene blocks is equal to or greater than 50 percent, and the ethylenebutylene block is hydrogenated leaving no more than 10 percent unsaturation which has been grafted with at least one olefinic carboxylic acid acylating agent and then derivatized with an aminoaromatic compound from the group consisting of aminopyridines, aminopyrazines and aminopyrimidines, and a lubricating oil composition containing same are provided.
摘要:
Improvements in dispersant viscosity index improvers having antioxidant properties and their use in lubricating oils are disclosed. An ethylene-propylene copolymer rubber has grafted thereon a vinyl monomer having an epoxy group to form a precursor which is condensed with a 5-aminotetrazole by ring opening of the pendent epoxide group.
摘要:
The Mannich reaction products of certain diaminopropanes with formaldehyde and salicylic acids are potent carburetor detergents and corrosion inhibitors in hydrocarbon fuels, particularly in gasoline.
摘要:
Disclosed are beta-amino acid derivatives which impart friction reducing properties to lubricating compositions. The additives of the invention are bifunctional carboxylic acid salts and amides derived from the basic hydrolysis of a cyanoethylated amine.
摘要:
Multifunctional viscosity index improvers for lubricating oils containing an EPM or EPDM polymer onto which has been grafted with an unsaturated reactive monomer and thereafter reacted with amino alkylphenothiazine.
摘要:
Middle distillate fuels may be treated to improve storage stability by addition of, as additive, an acrylate polymer containing moieties derived from an N-heterocyclic amine such as 4-vinyl pyridine or the enamine ester of morpholine and propionaldehyde.
