Abstract

Sulfurization with elemental sulfur of a fatty mixture consisting essentially of about 80-95 weight percent prime burning lard oil and about 5-20 weight percent alkyl oleate yields a sulfur-containing oil-soluble product suitable for use as a substitute for sulfurized sperm oil additives for imparting extreme pressure properties to high aniline point mineral oil lubricants.

Claims

1. A SULFURIZED FATTY OIL COMPOSITION CONSISTING ESSENTIALLY OF A BLEND OF (A) ABOUT 80 WEIGHT PERCENT TO ABOUT 95 WEIGHT PERCENT PRIME BURNING LARD OIL AND (B) ABOUT 5 WEIGHT PERCENT TO ABOUT 20 WEIGHT PERCENT ALKYL OLEATE SULFURIZED TO CONTAIN ABOUT 8 WEIGHT PERCENT TO ABOUT 12 WEIGHT PERCENT BOUND SULFUR AND NOT MORE THAN 0.3 WEIGHT PERCENT FREE SULFUR, SAID ALKYL OLEATE BEING A MIXTURE OF ALKYL ESTERS OF SATURATED AND UNSATURATED FATTY ACIDS HAVING 14 TO 18 CARBONS CONTAINING AT LEAST 50 WEIGHT PERCENT UNSATURATED FATTY ACIDS WITH NOT MORE THAN 10 WEIGHT PERCENT OF UNSATURATED FATTY ACIDS CONTAINING CONJUGATED DUBLE BONDS IN THE UNSATURATED FATTY ACID FRACTION AND SAID ALKYL GROUP HAVING 1 TO 3 CARBON ATOMS.

2. The composition of claim 1 wherein (b) is methyl oleate.

3. The composition of claim 2 wherein the amount of bound sulfur is about 9 weight percent to about 11 weight percent.

4. The composition of claim 2 wherein (a) is about 85 weight percent to about 93 weight percent, and (b) is about 7 weight percent to about 15 weight percent.

5. The composition of claim 2 wherein (a) is about 80 weight percent, (b) is about 20 weight percent, and the amount of bound sulfur is about 10 weight percent.
