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:
Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.
