摘要:
3-Halo-1,2,4-thiadiazolyl 5-disulfides and 1,2,4-thiadiazolyl 3,5-bis(disulfides) are prepared by reaction of mercaptans with the corresponding sulfenyl chlorides. The disulfides are useful as corrosion inhibitors in lubricants.
摘要:
Aqueous dispersions of film-forming polymers having improved wet adhesion and blister resistance capabilities are produced by grafting certain substituted acrylamides, such as diacetone acrylamide and hydroxymethylated derivatives thereof, on polyvinyl acetate and similar latices. The aqueous dispersions are useful as paints, adhesives, and the like.
摘要:
Polymerizable amido-substituted sulfonic acids, especially 2acrylamido-2-methylpropanesulfonic acid, react with epoxides (especially ethylene and propylene oxide) to form hydroxycontaining esters which are useful for the production of dyeable and dyeability-improving polymers.
摘要:
Lubricant compositions comprising a novel additive combination to improve the anti-oxidant and rust-inhibiting properties of these compositions are disclosed. The additive combination comprises an alkylene dithiocarbamate and an aliphatic hydrocarbon-substituted succinic acid or certain derivatives thereof. Lubricant compositions containing the novel additive combination are useful in a variety of applications.
摘要:
Oil-soluble polymers of N-3-aminoalkyl acrylamides, especially N-(1,1-dimethyl-3-dimethylamino-propyl)acrylamide, are obtained by copolymerization with a monomer (especially an alkyl acrylate or methacrylate) containing an alkyl group with at least about 8 carbon atoms. These polymers are useful as dispersants and viscosity modifiers for lubricants.
摘要:
Metal surfaces are cleaned, prior to phosphating or the like, with compositions containing alkali metal (especially sodium) silicates and chlorides, and preferably also containing surfactants and chelating agents. These compositions have cleaning power comparable to phosphate-containing cleaners and cause less water pollution upon discharge into natural waterways.
摘要:
ESTER-CONTAINING COMPOSITIONS PREPARED BY REACTING A HIGH MOLECULAR WEIGHT CARBOXYLIC ACID ACYLATING AGENT WITH P3POLYOXYALKYLENE ALCOHOL DEMULSIFIERS FOR AQUEOUS EMULSIONS. THE ESTER-CONTAINING COMPOSITIONS ARE USEFUL AS ADDITIVES IN NORMALLY LIQUID FUELS AND LUBRICANTS.
摘要:
A dispersion comprising a non-polar organic liquid, an alkaline earth metal salt of a fatty acid or substituted fatty acid, and a dispersant is effective as a rheology modifier for imparting plastic flow to printing inks. The dispersant is characterized by the presence therein of at least one acyl, acyloxy or acylimidoyl group, typically derived from a carboxylic acid having at least about 50 carbon atoms, and at least one radical containing a nitrogen or oxygen atom connecting said acid-derived group to a hydrocarbon or substituted hydrocarbon radical.
摘要:
THIS INVENTION IS DIRECTED TO OIL-SOLUBLE ACYLATED-NITROGEN COMPOSITIONS HAVING DEMULSIFYING CHARACTERISTICS OBTAINED BY REACTING AT LEAST ONE CARBOXYLIC ACID OR CARBOXYLIC ACID-PRODUCING COMPOUND HAVING AT LEAST 8 ALIPHATIC CARBON ATOMX S WITH AN EFFECTIVE AMOUNT OF AT LEAST ONE HIGH MOLECULAR WEIGHT POLYOXYALKYLENE POLYAMINE; SAID POLYAMINE HAVING AN AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 200. THE ACYLATED-NITROGEN COMPOSITIONS OF THIS INVENTION ARE PARTICULARLY USEFUL AS ADDITIVES FOR A VARIETY OF OLEGINOUS MATERIALS INCLUSING, FOR EXAMPLE, LUBRICATING OILS, HYDRAULIC FLUIDS, LUBRICANTS, FUELS, E.G., GASOLINE, DIESEL FUELS, ETC.
