| Abstract: | Effectiveness of
2-methylpiperazinedithiocarbamato(2-Mepipzdtc) complexes of Cu(II)
and Zn(II), diethyldithiophosphato (Et2dtp) complex of Ni(II) and
its -picoline
diadduct, and pyrrolidine dithiocarbamato complex of Cu(II) are evaluated as
antioxidant lubricating oil additives by measurement of viscosity, acid number,
IR spectral and thermal studies. All the complexes at 0.25 and 0.5 wt% show
antioxidant property. Zn(2-Mepipzdtc)2 as well as Ni(Et2dtp)2(-pic)2
were found to be most effective antioxidants among these compounds. The
antioxidant behaviour has been explained on the basis of hydroperoxide
decomposition and radical scavenger mechanism. |
