Preparation of dicyclohexyl disulfide through the reaction of cyclohexyl chloride with sodium disulfide is given. 讨论了氯代环己烷与二硫化钠反应制备二环己基二硫化物的方法。
The paper discusses the synthesis method of a new polydentate ligand, sodium N, N-bis ( 2-benzimidazolylmethylene) dithiocarbamate, using N, N-bis ( 2-benzimidazylomethyl) amine with carbon disulfide in the presence of sodium hydroxide. 本文论述了N,N二(2苯并咪唑亚甲基)胺与二硫化碳在氢氧化钠的存在下合成新型多齿配体N,N二(2苯并咪唑亚甲基)二硫代氨基甲酸钠的方法。
The results showed that the coexistence of catalyst and alkaline made the sodium mercaptide changed into disulfide which entered the refined LPG which was the main reason of the disqualification of desulfurization. 结果表明,催化剂碱液(剂碱)共存是造成碱相中的硫醇钠容易转化为二硫化物而导致精制后的液化气硫含量不合格的原因。
