Haloalkyl hydroxy-aromatic condensation products as fuel additives

Patent ·
OSTI ID:5538114
Condensation products made by reacting an alpha-haloalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants. The number of carbon atoms in the aromatic hydrocarbyl compound's substituents are each about 25 while the haloalkyl group contains from one to about carbons. The acid or nitrile reactant usually contains three to about forty carbons. Products made from halomethyl alkylsubstituted phenols and alpha , beta -olefinic diacid derivatives such as maleic anhydride are particularly useful. Similarly useful products can be made from these condensation products by further reacting their acid, acid derivative or nitrile groups with alcohols, polyols, monoamines, polyamines, metal salts or metals.
