Lubricants and fuel containing high molecular weight carboxylic acid acylating agents and their derivatives

Claim 1

A LUBRICANT OR FUEL COMPOSITION COMPRISING, RESPECTIVELY, A MAJOR AMMOUNT OF LUBRICATING OIL OR A NORMALLY LIQUID FUEL AND 0.0001% TO 20% BY WEIGHT OF AT LEAST ONE OIL-SOLUBLE HIGH MOLECULAR WEIGHT CARBOXYLIC ACID ACYLATING AGENT PREPARED BY A PROCESS COMPRISING INTIMATELY CONTACTING CHLORINE WITH A REACTION MIXTURE AT A TEMPERATURE OF AT LEAST 140*C. AND UP TO THE DECOMPOSITION TEMPERATURE, SAID REACTION MIXTURE BEING SELECTED FROM THE GROUP CONSISTING OF: I. A FIRST REACTANT WHICH IS AT LEAST ONE (A) MONOCARBOXYLIC ACID ACYLATING AGENT CONTAINING AN AVERAGE OF AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS IN THE ACYL MOIETY EXCLUSIVE OF THE CARBOXYL FUNCTIONS ANDAT LEAST ONE (B) LOW MOLECULAR WEIGHT CARBOXYLIC ACID REACTANT WHICH IS AN ETHYLENICALLY UNSATURATED MONO- OR POLYCARBOXYLIC ACID ACYLATING AGENT CONTAINING A TOTAL OF UP TO ABOUT TWENTY CARBON ATOMS IN THE ACRYL MOIETY, THE MOLE RATIO OF (A) TO (B) BEING SUCH THAT THERE IS AT LEAST 0.5 MOLE OF (B) FOR EACH MOLE OF (A) WITH THE PROVISO THAT (B) PROVIDES A MINIMUM OF ONE EQUIVALENT OF CARBOXYLIC ACID REACTANT IN THE REACTION MIXTURE PER MOLE OF (A); OR II. AT LEAST ONE (C) ETHYLENICALLY UNSTAURATED ALIPHATIC HYDROCARBON OR SUBSTITUTED ALIPHATIC HYDROCARBN REACTANT CONTAINING AN AVERAGE OF AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS, AT LEAST ONE (D) LOW MOLECULAR WEIGHT MONOCARBOXLIC ACID REACTANT WHICH IS AN ETHYLENICALLY UNSATURATED MONOCARBOCYLIC ACID ACYLATING AGENT CONTAINING UP TO ABOUT 20 CARBON ATOMS IN THE ACYL MOIETY, AND AT LEAST ONE (E) LOW MOLECULAR WEIGHT POLYCARBOXYLIC ACID REACTANT WHICH IS AN ETHYLENICALLY UNSATURATURED POLYCARBOXYLIC ACID ACYLATING AGENT CONTAINING UP TO ABOUT 20 CARBON ATOMS IN THE ACYL MOIETY, THE MOLE RATIO OF (C): (D): (E) BEING SUCH THAT THERE IS AT LEAST ABOUT 0.5 MOLE OF EACH OF (D) AND (E) PER MOLE OF (C) WITH THE PROVISO THAT THE COMBINED AMOUNT OF (D) AND (E) PROVIDES A MINUMUM OF AT LEAST TWO EQUIVALENTS OF LOW MOLECULAR WEIGHT MONOAND POLYYCARBOXYLIC ACID REACTANTS PER MOLE OF (C), THE TOTAL AMOUNT OF CHLORINE EMPOLYED IN SAID PROCESS BEING SUFFICIENT TO PROVIDE A T LEAST ABOUT 0.8 MOLE OF CHLORINE PER MOLE OF (B) OR AT LEAST ABOUT 0.8 MOLE OF CHLORINE PER THE TOTA NUMBER OF MOLES OF (D) AND (E), RESPECTIVELY.
