Abstract

Fuels, especially hydrocarbon fuels, and lubricants, especially lubricating oils, contain a class of anti-corrosion, anti-wear, anti-fatigue, and extreme pressure additives that are derived from 1,3-dithiolane-2-thiones.

Claims (16)

1. A composition comprising:

(A) a lubricating oil or a hydrocarbon fuel, and

(B) at least one 1,3-dithiolane-2-thione of formula (I):

wherein:

R 2 and R 4 are independently selected from the group consisting of hydrogen, alkyl, and alkenyl;

said alkyl and alkenyl groups are unsubstituted or substituted with OH, SH, oxirane, thiirane, or 1,3-dithiolane-2-thione, and

R 1 and R 3 are fused together to form a saturated ring of 5 or 6 carbon atoms.

2. The composition of claim 1 further comprising at least one phosphorus-containing additive.

3. The composition of claim 2 wherein at least one phosphorus-containing additive is a dihydrocarbyldithiophosphate.

4. The composition of claim 1 wherein the at least, one 1,3-dithiolane-2-thione of formula (II):

wherein: q is 1 or 2.

5. A method for improving the anti-corrosion, anti-fatigue, anti-wear, and extreme pressure properties of lubricating oils or hydrocarbon fuels comprising adding to said lubricating oils or hydrocarbon fuels a functional property-improving amount of at least one 1,3-dithiolane-2-thione of formula (I):

wherein:

R 2 and R 4 are independently selected from the group consisting of hydrogen, alkyl, and alkenyl;

said alkyl and alkenyl groups are unsubstituted or substituted with OH, SH, oxirane, thiirane, or 1,3-dithiolane-2-thione, and

R 1 and R 3 are fused together to form a saturated ring of 5 or 6 carbon atoms.
