Abstract:
OIL-SOLUBLE COMPOSITIONS PRODUCED BY REACTING POLYCARBOXYLIC ACID ACYLATING AGENTS HAVING AT LEAST FIFTY ALIPHATIC CARBON ATOMS WITH A DI- OR TRIHYDRIC ALCOHOL AND A POLYHYDRIC ALCOHOL HAVING AT LEAST FOUR HYDROXYL GROUPS ARE USEFUL AS ASHLESS DISPERSANTS IN LUBRICANTS AND FUELS. POLYOLEFIN-SUBSTITUTED SUCCINIC ANHYDRIDE SIMULTANEOUSLY TREATED WITH A MIXTURE OF TRISMETHYLOLPROPANE AND PENTAERYTHRITOL PRODUCES SUCH AN OIL-SOLUBLE COMPOSITION.
