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.

A product prepared by reacting, at a temperature of from about 100.degree. to about 200.degree. C., one mole of alkenylsuccinic acid, anhydride or acyl halide with from 0.05 to 5 moles of a hydroxylated primary amine selected from the group consisting of 1-amino-2-hydroxypropane, 1-amino-3-hydroxypropane, 1-amino-2,3-dihydroxypropane, 1-amino-2,3,4-trihydroxybutane, 1-(hydroxymethyl)aminoethane, tris(hydroxymethyl)-aminomethane, 1,1-bis (hydroxymethyl)aminoethane and 1-(hydroxymethyl)benzylamine and reacting the resulting product with a reactant selected from the group consisting of (1) from about 1 to about 2 moles per mole of said product of a boron compound of the formula ##STR5## in which each R' is individually selected from the group consisting of hydrogen and a C.sub.1 -C.sub.20 alkyl, aralkyl or aralkyl group, (2) from about 1 mole to about 2 moles per mole of said product of an organophosphonate of the formula ##STR6## in which R' is individually selected from the group consisting of hydrogen and a C.sub.1 -C.sub.20 alkyl, arayl, aralkyl or alkaryl group (3) or from about 1 mole to about 2 moles per mole of said product of an aldehyde of the formula ##STR7## in which R' is selected from the group consisting of hydrogen and a C.sub.1 -C.sub.20 alkyl, aryl, aralkyl or alkaryl, the reaction of the boron, phosphonate or aldehyde with said product taking place at from about 50.degree. to about 250.degree. C.
An organic fluid composition comprising a major proportion of a mineral lubricating oil, a synthetic lubricating oil, a grease prepared from these or a normally liquid hydrocarbon fuel and a detergent amount of a product prepared by reacting one mole of alkenylsuccinic acid, anhydride or acyl halide with from 0.05 to 5 moles of a hydroxylated primary amine selected from the group consisting of 1-amino-2-hydroxypropane, 1-amine-3-hydroxypropane, 1-amine-2,3-dihydroxypropane, 1-amino-2,3,4-trihydroxybutane, 1-(hydroxymethyl)aminoethane, tris(hydroxymethyl)-aminomethane, 1,1-bis(hydroxymethyl)aminoethane and 1-(hydroxymethyl) benzylamine and reacting the resulting product with a reactant selected from the group consisting of (1) from about 1 to about 2 moles per mole of said product of a boron compound of the formula ##STR8## in which each R' is individually selected from the group consisting of hydrogen and a C.sub.1 -C.sub.20 alkyl, aralkyl or aralkyl group, (2) from about 1 mole to about 2 mole of said product of an organophosphonate of the formula ##STR9## in which R' is individually selected from the group consisting of hydrogen and a C.sub.1 -C.sub.20 alkyl, arayl, aralkyl or alkaryl group or (3) from about 1 mole to about 2 moles per mole of said product of an aldehyde of the formula ##STR10## in which R' is selected from the group consisting of hydrogen and a C.sub.1 -C.sub.20 alkyl, aryl, aralkyl or alkaryl, the reaction of the boron, phosphonate or aldehyde with said product taking place at from about 50.degree. to about 250.degree. C.
