Bayer已报告氨基苯酚或氨基巯酚与脂肪族或芳香族的二羰基化合物缩合而成的Schiff碱,对某些金属离子有选择性反应(pH 1—9).目前此类Schiff碱已用作分析试剂的仅有乙二醛-双[隣羟基缩苯胺](GBHA),而其他类似试剂似尚未研究.作者等合成乙二醛-双[瞵巯基缩苯胺](GBMA),并试验其分析反应及用作为分析试剂的可能性.

Forty-three cations and thirty anions has been tested with glyoxal-bis(o-mercaptoanil).The following ions,Ag+,Au3+,Cd2+,Co2+,Cu2+,Hg2+2,Hg2+,Mn2+,Tl+,Tl3+,MoO2-4;and VO3-,give coloured precipitate which may be dissolved in suitable organic solvents,forming coloured solutions. The solubility of the precipitate formed depends greatly upon the pH value of the medium.
