摘 要:以一氯化硫和乙硫醇為原料,石油醚作溶劑,在0~5℃之間反應5h,經(jīng)縮合合成了二乙基四硫,實(shí)驗最佳反應摩爾比(乙硫醇∶一氯化硫)為2 1,收率84 0%,產(chǎn)品純度為89%。通過(guò)IR、1HNMR及高效液相色譜確定產(chǎn)品結構為二乙基四硫。 |

Abstract:Diethyl tetrasulfide was prepared by reacting sulfur monochloride with ethanthiol at 0~5℃ in petroleum ether. The reaction time was 5h. The optimum molar ratio of ethanthiol to sulfur monochloride was 2.1, and the yield of the product was summed up to 84.0%. The structure of the product was confirmed by IR,~1 HNMR and liquid chromatograph. |
Key words:sulfur monochloride; ethanthiol; diethyl tetrasulfide; synthesis; perfume |
