摘要:
Dimercaptothiadiazole adducts of hydroxyl-containing unsaturated compounds and their borated analogues provide effective multifunctional friction reducing and corrosion inhibiting properties to various lubricating fluids when incorporated therein.
摘要:
Mercaptothiadiazole adducts of unsaturated esters such as jojoba oil or pentaerythritol tetraoleate are highly effective multifunctional friction reducing and copper strip passivating additives for various lubricants.
摘要:
A borated oxazoline monoester, made by reacting a boron compound with the product of reaction between tris(hydroxymethyl)aminomethane and carboxylic acid is a new composition of matter. It is useful in a lubricating oil for reducing friction, and, therefore, fuel consumption in an internal combustion engine.
摘要:
Metal salts of hydrocarbyl oxazoline phosphorodithioic acids are novel compounds effective for reducing friction and wear when added to a lubricant.
摘要:
Products of reaction between a 2-hydroxyalkyl alkylamine or certain higher oxylated members, and a dihydrocarbyl phosphite have been found to be effective friction reducers and fuel reducing additives for internal combustion engines when such products are compounded with lubricants and liquid fuels.
摘要:
In preparing organic sulfides by reacting olefins (e.g., butylenes) with a sulfur halide to form a sulfohalogenated intermediate which is subsequently sulfurized and dehalogenated by reaction with an aqueous solution of an alkali metal sulfide compound to form a noncorrosive organic sulfide product of high sulfur content, the copper strip corrosion activity is improved by resulfurizing the sulfurized olefin by contacting it with additional aqueous metal sulfide in the presence of a lower molecular weight alcohol, such as isopropanol.
摘要:
Lubricant and fuel compositions having unique fuel saving properties are obtained by adding to the lubricant or fuel a product made by reacting a boron compound with a mixture of vicinal diols and long chain alcohols or hydroxyl-containing carboxylate esters.
