Abstract

This invention relates to malienated derivatives made from maleic anhydride, functionalized monomers, and one or more additional reagents, e.g., an oxygen-containing reagent (e.g., alcohol, polyol), a nitrogen-containing reagent (e.g., amine, polyamine, aminoalcohol), a metal and/or a metal compound. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food compositions, etc.)

First claim

The invention claimed is:

1. A malienated derivative composition comprising:
a functionalized monomer, which is 9-dodecenoic acid or an ester thereof;
wherein the functionalized monomer is reacted with maleic anhydride on the carbon-carbon double bond of the functionalized monomer to form a maleinated derivative; and
wherein the maleinated derivative is reacted with an oxygen-containing reagent, which is an alcohol containing from 1 to about 18 carbon atoms or a polyol containing from 2 to about 10 carbon atoms and from 2 to about 6 hydroxyl groups, to form a triester;
wherein the alcohol is methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, decanol, dodecanol, tetradecanol, hexadecanol, octadecanol, isopropanol, isobutanol, sec-butanol, tert-butanol, isopentanol, amyl alcohol, tert-pentanol, cyclopentanol, cyclohexanol, 2-ethylhexanol, allyl alcohol, crotyl alcohol, methylvinyl carbinol, benzyl alcohol, alpha-phenylethyl alcohol, beta-phenylethyl alcohol, diphenylcarbinol, triphenylcarbinol, cinnamyl alcohol, or a mixture of two or more thereof.

2. The composition of claim 1 wherein the oxygen-containing reagent is methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, decanol, dodecanol, tetradecanol, hexadecanol, octadecanol, isopropanol, isobutanol, sec-butanol, tert-butanol, isopentanol, amyl alcohol, tert-pentanol, cyclopentanol, cyclohexanol, 2-ethylhexanol, allyl alcohol, crotyl alcohol, methylvinyl carbinol, benzyl alcohol, alpha-phenylethyl alcohol, beta-phenylethyl alcohol, diphenylcarbinol, triphenylcarbinol, cinnamyl alcohol, or a mixture of two or more thereof.

3. The composition of claim 1 wherein the oxygen-containing reagent is ethylene glycol, glycerol, trimethylolpropane, 1,2-propanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 2,3-butanediol, 2-ethyl-1,3-propanediol, 2-ethyl-2-butyl-1,3-propanediol, neopentyl glycol, 2,2,4-trimethyl-1,3-pentanediol, pentaerythritol, sorbitol, or a mixture of two or more thereof.

4. The composition of claim 1 wherein the functionalized monomer is methyl 9-dodecenoate.
