Abstract:Antimony N,N-diethyldithiocarbamate was synthesized with diethylamine, carbon disulfide and antimony trioxide (or antimony sulfide). Its chemical composition was determined by elementary analysis, IR,¹HNMR and ¹³CNMR spectra. The influences of reaction time, temperature, molar ratio of raw materials, selection of solvents and purification method on synthesis technology were discussed. Its applications in polyvinyl chloride (PVC) resin as a heat stabilizer and in lithium complex grease as an exterme pressure antiwear agent were studied.

Key words: N,N-diethyldithiocarbamate　preparation　stability　extreme pressure and wear resistance
