Abstract: THE NOVEL SULFINYL-CONTAINING ALKENYLSUCCINATES OF THIS INVENTION ARE USEFUL AS DISPERSANTS, CORROSION INHIBITORS AND ANTI-WEAR AGENTS PARTICULARLY IN LUBRICATING OIL AND FUEL COMPOSITIONS. THE NOVEL SULFINYL COMPOUNDS ARE PREPARED BY REACTING (1) AN ALKENYLSUCCINIC ANHYDRIDE, AN ALKENYLSUCCINIC ACID OR AN ALKENYLSUCCINAMIC ACID AND (2) AT LEAST ONE SULFINYL-CONTAINING HYDROXY COMPOUND HAVING THE FORMULAS:

R1-S(=O)-(R2-O)Y-H, R1-S(=O)-R2-(O-R3-S(=O)-R4)N-OH OR

HO-(R2-S(=O)-R4-O)N-H

WHEREIN

Y IS AN INTEGER FROM 1 TO ABOUT 50 OR MORE AND N IS AN INTEGER FROM 1 TO 40, R1 IS SELECTED FROM THE GROUP CONSISTING OF (A) ALKYL RADICAL CONTAINING FROM 1 TO 2J CARBON ATOMS, (B) AN ARYL RADICAL (C) AN ARALKYL RADICAL WHEREIN THE ALKYL PORTION OF THE RADICAL CONTAINS FROM 1 TO 4 CARBON ATOMS AND (D) AN ALKARYL RADICAL WHEREIN THE ALKYL PORTION CONTAINS FROM 1 TO 24 CARBON ATOMS, R2 IS ALKYLENE RADICAL HAVING 2 TO 5 CARBON ATOMS, AND R3 AND R4 ARE ALKYLENE RADICALS HAVING 2 TO 5 CARBON ATOMS, A PHENYLENE RADICAL OR A (C1-C4) ALKYL SUBSTITUTED PHENYLENE RADICAL WITH THE PROVISIO THAT N IS 1 WHEN R3 AND R4 ARE PHENYLENE OR (C1-C4) ALKYL SUBSTITUTED PHENYLENE.
