室温合成二硫化二正丁基黄原酸酯及其表征
摘要:
以正丁醇、氢氧化钠和二硫化碳为原料,水作溶剂合成正丁基黄原酸钠,再与一氯化硫反应,室温条件下合成对称的二硫化二正丁基黄原酸酯,并探讨了反应条件对合成正丁基黄原酸钠和二硫化二正丁基黄原酸酯产率的影响。通过红外(FT-IR)、核磁(1H NMR)、质谱(MS)及元素分析等技术手段确定了产物的结构。优化的合成条件为:n(正丁基黄原酸钠):n(S2Cl2)=2:1.1,温度为室温,溶剂为THF,反应时间为2 min,产率可达83.2%,反应条件温和,反应迅速、收率高。

Room Temperature Synthesis and Characterization of Dibutyl Xanthate Disulfide
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 n-butylxanthate 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.
