Soluble oil

Claim 1

A SOLUBLE OIL COMPOSITION CONSISTING ESSENTIALLY OF A MINERAL LUBRICATING OIL, FROM ABOUT 5 PERCENT TO ABOUT 30 PERCENT BY WEIGHT OF AN EMULSIFYING AGENT CAPABLE OF PROMOTING THE FORMATION OF AN OIL-IN-WATER EMULSION, FROM ABOUT 5 PERCENT TO ABOUT 20 PERCENT BY WEIGHT OF A CORROSIVE SULFUR-CONTAINING EXTREME PRESSURE AGENT SELECTED FROM THE GROUP CONSISTING OF SULFURIZED ANIMAL, MARINE AND VEGETABLE OILS CONTAINING FROM ABOUT 12 TO ABOUT 20 PERCENT OF SULFUR, SULFURIZED MINERAL OILS CONTAINING UP TO ABOUT 5 PERCENT OF ADDED SULFUR, SULFURIZED TERPENES, ORGANIC POLYSULFIDES AND MERCAPTANS, AND FROM ABOUT 5 PERCENT TO ABOUT 30 PERCENT BY WEIGHT OF AN OILSOLUBLE, PHOSPHORUS-, SULFUR- AND CALCIUM-CONTAINING OXIDIZED HYDROCARBON REACTION PRODUCT PRODUCED BY THE METHOD WHICH COMPRISES THE STEPS OF: (1) FORMING A MIXTURE COMPRISING (A) A HYDROCARBON HAVING A MOLECULAR WEIGHT OF FROM ABOUT 200 TO 1000 AND WHICH IS SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC HYDROCARBONS AND AROMATIC HYDROCARBONS HAVING AT LEAST ONE NUCLEAR HYDROGEN ATOM SUBSTITUTED BY AN ALIPHATIC RADICAL TO PROVIDE A TOTAL OF AT LEAST 8 ALIPHATIC CARBON ATOMS PER MOLECULE THEREIN, AND MIXTURES THEREOF, AND (B) FROM ABOUT 0.5% TO ABOUT 25%, BASED ON THE WEIGHT OF SAID HYDROCARBON, OF CALCIUM HYDROXIDE, (2) CONTACTING SAID MIXTURE WITH AN OXIDIZING GAS AT A TEMPERATURE OF FROM ABOUT 125*C. TO ABOUT 325*C. TO EFFECT OXIDATION OF SAID HYDROCARBON AND REACTION OF SAID CALCIUM 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 CALCIUM INTO THE OXIDIZED HYDROCARBON; (4) REACTING THE PRODUCT FROM (3) WITH FROM ABOUT 5% TO ABOUT 20%, BY WEIGHT, BASED ON THE WEIGHT OF HYDROCARBON CHARGED IN (1), OF A PHOSPHORUS SULFIDE, AT A TEMPERATURE OF FROM ABOUT 75*C. TO ABOUT 150*C., TO FORM A PHOSPHORUS-, SULFUR- AND CALCIUM-CONTAINING PRODUCT; (5) PROVIDING A MIXTURE OF THE REACTION PRODUCT FROM (4) WITH FROM ABOUT 2% TO ABOUT 25%, BY WEIGHT, BASED ON THE HYDROCARBON CHARGED IN (1), OF A CALCIUM HYDROXIDE, AND WATER, AT A TEMPERATURE BELOW THE BOILING POINT OF WATER; (6) SUBSTANTIALLY COMPLETELY DEHYDRATING THE MIXTURE FORMED IN (5) AND (7) SUBJECTING THE DEHYDRATED MIXTURE TO FILTRATION TO REMOVE INSOLUBLES THEREFROM.
