Abstract
The invention relates to a novel asymmetrical, secondary dialkylamine-based molybdenum dithiocarbamate with improved friction reducing performance, viscosity and solubility, and lubricating compositions containing the same. The compounds are produced from asymmetrical dialkylamine of the formula R1-NH—R2 where R1 and R2 are different, and are independently selected from alkyl groups C3 to C19. In a preferred embodiment, R3 and R4 are different and are independently selected from alkyl groups C3 to C19. The molybdenum dithiocarbamates can be represented by the following formula:
