Petroleum oxidate and calcium derivatives thereof |
| abstract |
A petroleum oxidate of gel resistant properties characterized by a Neut. No. between about 40 and 50, a Sap. No. between about 85 and 105, a specific gravity between about 0.99 and 1.03, a viscosity (SUS at 210 DEG F.) of between about 1200 and 2500 and a melting point of between about 85 DEG and 115 DEG F.; a calcium soap thereof having a calcium content of between about 1.2 and 1.9 wt. % and a melting point between about 155 DEG and 230 DEG F. of gel resistant properties under cutback conditions; said oxidate, calcium soap and cutback thereof respectively prepared by contacting a deasphalted naphthene base residual oil having a molecular weight of between about 300 and 900, a saturate content between about 40 and 60 wt. %, an aromatic content between about 60 and 40 wt. %, a methylene to methyl group mole ratio of between about 1:1 and 2.5:1, and an SUS viscosity (210 DEG F.) of between about 150 and 170, with air at an air rate of between about 5 and 40 SCFH/lb. residual oil charge in the presence of between about 0.2 and 2 lbs. metaliferous oxidation catalyst per pound charge oil under a pressure of between about 0 and 500 atmospheres at a temperature between about 250 DEG and 400 DEG F. for a period of normally between about 1 and 5 hours to form said petroleum oxidate which is then further reacted with calcium hydroxide in a hydroxide amount of between about 100 and 125 wt. % of stoichiometric at a temperature of between about 275 DEG and 357 DEG F. and cutting back the formed calcium soap with inert petroleum hydrocarbon solvent to form a cutback calcium oxidate soap composition containing between 0.1 and 90 wt. % of said oxidate soap of corrosion inhibiting and anti gel properties. |
