摘要:
The invention herein is concerned with novel compositions of matter made by reacting phosphorus pentasulfide with a polyhydroxyester and then followed by reaction with a salt-forming metal-containing compound and lubricant compositions containing same.
摘要:
Products made by reacting (i) an alkenylsuccinic compound with (ii) an arylamine and (iii) an alkanolamine, an aminomethane or a hindered alcohol and borated reaction products thereof which provide superior dispersant and antioxidant activity to lubricant compositions when incorporated therein.
摘要:
Novel dicarboxylic ester-acids resulting from the condensation of an alkenylsuccinic anhydride with an aliphatic hydroxy acid having from 2 to about 18 carbon atoms and amine salts of said ester-acid are useful as rust or corrosion inhibitors in organic compositions.
摘要:
Organic compositions, which are normally susceptible of corroding copper, are provided, containing, in an amount sufficient to inhibit such corrosion, benzotriazole derivatives said derivatives having been prepared by reacting (A) benzotriazole and (B) a reactant selected from the group consisting of hydrocarbyl carboxylic acids having at least 18 carbon atoms, mono and di-substituted organic phosphates, and mono and di-substituted phosphonates wherein the organic substituent contains at least 15 carbon atoms and wherein said reaction is conducted at a temperature from about 100.degree.C to about 200.degree.C and in a mole ratio of (A) to (B) from about 1:1 to about 1:0.5.
摘要:
Borated reaction products of alkenyl succinic compounds, aryl amines and aminoalcohols are highly effective dispersant and antioxidant/anticorrosion additives for lubricant compositions.
摘要:
Load-carrying properties of gear oils are increased by the addition of triazole derivatives obtained by reacting benzotriazole or an alkylbenzotriazole with alkylphosphates, alkylphosphonates, or primary fatty amines, a naphthenyl oxazoline, or an alkenylsuccinyl mono- or bis-oxazoline.
摘要:
Alkenylsuccinic anhydride is reacted with an amino alcohol, such as tris(hydroxymethyl)aminomethane, to provide intermediate reaction products from which novel derivatives are obtained by reacting the said intermediate product with boric acid or organoborates, organophosphonates and aldehydes. The intermediate reaction product prepared from tris(hydroxymethyl)aminomethane contains unexpectedly an oxazoline component when the reaction is carried out at 175.degree. C or below, preferably 100.degree. to 175.degree. C. The reaction products and their derivatives are particularly useful in lubricants, fuels or other industrial fluids as detergents.
摘要:
Alkoxy borates of alkylated phenols have been found to be effective cleanliness agents for lubricants and additives for improving the dropping point of greases.
摘要:
A cutting oil composition comprises a major amount of mineral lubricating oil and minor amounts of (A) a sulfurized oil and (B) the reaction product of a polyalkenylsuccinic anhydride with a polyethyleneglycol or a polypropyleneglycol or such reaction product further reacted with sulfur or with phosphorus pentasulfide.
