性质描述: 蓝黑色结晶性粉末。熔点165-169℃(分解)。易溶于氯仿、四氯化碳,稍溶于醇,不溶于水。
生产方法: 按下述步骤制备。1.苯肼二硫代甲酸苯肼盐的制备。将13g苯肼溶于60ml乙醚中,滴加5.2ml二硫化碳。将生成的白色沉淀滤出,用乙醚洗涤,得约15g。2.二苯二氨基硫脲的制备。将上述生成物置于烧杯中,在96-98℃的水浴上加热,物料熔融后放出硫化氢而转为淡黄以的胶状物。若有氨气放出,则移出热浴,用水冷却。再用冰冷却。再用冰冷却,加入15ml水无水乙醇,自冰浴中取出,搅拌下稍热,这时胶状物变成结晶状产物,抽滤,用乙醇洗涤,得约7.5g。3.双硫腙的制备。将上述所得二苯二氨基硫脲加到苛性钾溶液(6g氢氧化钾溶于60ml无水甲醇)中,在沸水浴上回流5min,取出在冰浴中冷却。过滤,滤液用硫酸酸化至刚果红试纸变色,析出深蓝色沉淀。抽滤,将沉淀物再用苛性钾溶液、硫酸处理一遍,抽滤后用水洗至无硫酸根存在。在40℃烘干,得双硫腙约3g。
用途: 该品是测定微量沿的络合指示剂,并用于测定钴、铜、汞、锌和银等。

应用
Dithizone is used as an indicator for minute amounts of lead. It acts as a chelating agent for heavy metal poisoning. As a ligand, it forms complexes with metals like zinc, lead and mercury. Further, it is used to assess the purity of human pancreatic islet preparations, which is used for transplantation in patients with type 1 diabetes. In addition to this, it is used as a titrant in the quantitative determination of heavy metals.
