Abstract: Sodium n-butylxanthate obtained from n-butyl alcohol, sodium hydroxide and carbon disulfide in water was converted to symmetrical dibutyl xanthate disulfide by reacting with disulfur dichloride(S2Cl2) at room temperature. The effects of reaction conditions on the yields of the sodium nbutylxanthate and dibutyl xanthate disulfide were investigated respectively. Characterizations of dibutyl xanthate disulfide were done using Fourier transform infrared(FT-IR) spectroscopy, 1H nuclear magnetic resonance(1H NMR)spectroscopy, mass spectroscopy(MS) and elemental analysis techniques. In optimized reaction conditions, the molar ratio of sodium n-butylxanthate to S2Cl2 is 1∶1.1 in THF solvent. The reaction completes within 2 min at room temperature to give up to 83.2% yield.

Key words: sodium n-butyxanthate, dibutyl xanthate disulfide, accelerant, synthesis, structure characterization
