Phosphorus- and sulfur-containing complex metal salts of oxidized hydrocarbons and oil compositions thereof

Claim 1

AN OIL-SOLUBLE, PHOSPHORUS-, SULFUR- AND METAL-CONTAINING OXIDIZED HYDROCARBON REACTION PRODUCT PRODUCED BY THE METHOD WHICH COMPRISES THE STEP OF (1) FORMING A MIXING COMPRISING (A) A HYDROCARBON HAVING A MOLECULAR WEIGHTS OF FROM ABOUT 200 TO 1000 AND WHICH IS SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC HYDROCARBONS AND AROMATIC HYDROCARBON HAVING AT LEAST ONE NUCLEAR HYDROGEN ATOM SUBSTITUTED BY AN ALIPHATIC RADICAL TO PROVIDE A TOTAL OF AT LEAST 8 ALIPHATIC RADICAL PER MOLE THEREIN, AND MIXTURES THEREOF, AND (B) FROM ABOUT 0.5% TO ABOUT 25%, BASED ON THE WEIGHT OF SAID HYDROCARBON OF A METAL HYDROXIDE, THE METAL CONSTITUENT OF WHICH IS SELECTED FROM GROUPS I AND II OF MENDELEEFF''S PERIODIC TABLE OF THE ELEMENTS (2) CONTACTING SAID MIXTURE WITH AN OXIDIZING GAS AT A TEMPERATURE OF FROM ABOPUT 125* C. TO ABOUT 325* C. TO EFFECT OXIDATION OF SAID HYDROCARBON AND REACTION OF SAID METAL HYDROXIDE WITH THE OXIDIZED HYDROCARBON, (3) CONTINUING THE OXIDATION FOR A TIME SUFFICIENT TO INCORPORATE FROM ABOUT 0.05% TO ABOUT 3.0% BY WEIGHT, OF METAL, INTO THE OXIDIZED HYDROCARBON (4) REACTING THE PRODUCT FROM STEP 3 WITH FROM ABOUT 5% TO ABOUT 20%, BY WEIGHT, BASED ON THE WEIGHT OF HYDROCARBON CHARGED IN STEP 1, OF A PHOSPHORUS SULFIDE, AT A TEMPERATURE OF FROM ABOUT 75* C. TO ABOUT 150* C., TO FORM A PHOSPHORUS-, SULFUR, AND METAL-CONTAINING PRODUCT, (5) PROVIDING A MIXTURE OF THE REACTION PRODUCT FROM STEP 4 WITH FROM ABOUT 2% TO ABOUT 25% BY WEIGHT BASED ON THE HYDROCARBON CHARGED IN STEP 1, OF A METAL HYDROXIDE, THE METAL CONSTITUENT OF WHICH IS SELECTED FROM GROUPS I AND II OF MENDELEEF''S PERIODIC TABLE OF THE ELEMENTS, AND WATER, AT A TEMPERATURE BELOW THE BOILING POINT OF WATER, (6) SUBSTANTIALLY COMPLETELY DEHYDRATING THE MIXTURE FORMED IN STEP 5 AND (7) SUBJECTING THE DEHYDRATED MIXTURE OF FILTRATION TO REMOVE INSOLUBLES THEREFROM.
