Lubricant composition containing sulfurized and chlorinated alkylene polyamine reaction product

Abstract

Abstract 1. A LUBRICATING COMPOSITION COMPRISING A MAJOR PROPORTION OF A MINERAL OIL LUBRICATING VISCOSITY CONTAINING A MINOR DETERGENT AMOUNT OF AN OIL-SOLUBLE ASHLESS SULFURIZED AND CHLORINATED ALKYLENE POLYAMIDE REACTION PRODUCT PREPARED BY CHLORINATING A REACTION PRODUCT OF SULFUR AND A POLYOLEFIN CONTAINING A TRITHIONE USING AT LEAST A MOLE OF CHLORINE PER MOLE OF TRITHIONE AT A TEMPERATURE RANGING FROM ABOUT 20 TO 95*C. TO FORM A CHLORINATED INTERMEDIATE PRODUCT, SAID TRITHIONE BEING REPRESENTED BY THE FORMULA: 3-(S=),4-R'',5-R-3H-1,2-DITHIOLE IN WHICH R AND R'' REPRESENT HYDROGEN OR A HYDROCARBYL RADICAL HAVING FROM ABOUT 50 TO 125 CARBON ATOMS, AT LEAST ONE OF R AND R'' REPRESENTING AN ALIPHATIC HYDROCARBON RADICAL, AND, REACTING INTERMEDIATE PRODUCT WITH A POLYAMIDE IN THE PROPORTION OF 1 TO 5 MOLE OF SAID POLYAMINE PER MOLE OF SAID INTERMEDIATE PRODUCT AT A TEMPERATURE IN THE RANGE OF 100 TO 275*C., SAID POLYAMIDE BEING REPRESENTED BY THE FORMULA H2N-(R"-NH)XH IN WHICH R" IS A DIVALENT ALKYLENE RADICAL HAVING FROM 2 TO 6 CARBON ATOMS AND X IS AN INTEGER RANGING FROM 1 TO 6.
