Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An alkyl phenol having from about 20 to about 300 carbon atoms, formaldehyde and trishydroxymethylaminomethane are reacted and the resulting product is then reacted with boric acid, dialkyl phosphonate or a diaryl phosphonate to produce the corresponding borate or phosphonate derivatives. These derivatives are particularly useful as detergents in organic media such as lubricating oils, greases, fuels, heat-exchange fluids and transmission fluids.

Abstract: Reaction products, useful as anti-corrosion inhibitors, are provided of (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 hydrocarbyl phosphates and mono- and di-substituted hydrocarbyl phosphonates wherein the hydrocarbyl 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) of from about 1:1 to about 1:0.5.

Abstract: 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.
