like pyridine, triethylamine, ethylenediamine, hexamethylenetetramine, 4,4‘-bipyridine, diethylamine, dicyclohexylamine, etc. Experiments were carried out to study the activity of these homogeneous scavengers to get maximum conversion, yield, and purity of the product. Reaction temperature, reaction time, substrate-to-scavenger ratio, and solvent requirements were studied to optimize the reaction conditions
ñ,ñ'-二氯双(2,4,6-三氯二苯基)尿素,也称为2-氯甲醇(CC-2),是芥菜(SM)的潜在去污剂,也被称为双(2-氯乙基)硫化物(HD) ),著名的战争代理。已经开发了一种新方法,用于通过二苯脲(DPU)通过称为六氯甲酰苯胺(HCC)的中间体合成CC-2。在35-100℃的温度范围内,在几种均相的HCl清除剂(例如吡啶,三乙胺,乙二胺,六亚甲基四胺,4,4'-联吡啶,二乙胺,二环己基胺等)的存在下,研究了DPU向HCC的转化。进行了研究以研究这些均质清除剂的活性,以获得最大的转化率,收率和产品纯度。反应温度,反应时间,底物与清除剂的比例,研究了溶剂要求,以优化反应条件。发现吡啶(产物纯度〜80%,产率〜89%)和乙二胺(产物纯度〜85%,产率〜70%)对改善反应性能均有效。
