| Abstract: | Tetraethyl thiuram disulfide was synthesized one step from diethylamine and carbon bisulfide with hydrogen peroxide(27.5%) as oxidant. Factors influencing the reaction yield were studied, such as ratio of reagents, reaction temperature, reaction time and solvents. The optimum technical conditions is as follow: ethanol as solvent, n(C_2H_5)_2NH]∶n(CS_2)∶n(H_2O_2,27.5%)=1.05∶1.00∶1.00, The reaction was carried out for 1?h at 20～30?℃ to give tetraethyl thiuram disulfide in 88.0% yield. |
