漂兰6B(ECB)是合成铬天青S(CAS)的原料,二者同属三苯基甲烷染料。铬天青S已被广泛用作络合反应中的显色剂,而以漂兰6B作显色剂的络合反应研究得很少。Vekhande等报导了稀土与漂兰6B及溴化十六烷基三甲铵(CTAB)在弱酸性介质中形成三元络合物,但漂兰6B作为四元络合反应的显色剂尚未见报导。在本文中系统地研究了稀土与漂兰6B,
Alchemist 6B (ECB) is the raw material for the synthesis of chrome azure S (CAS), both of which belong to the group of triphenylmethane dyes. Chromium Azure S has been widely used as a complexation reaction of the developer, and to drift blue 6B as a complexing agent rarely studied. Vekhande et al. Reported that a ternary complex of rare earths with blue bromine 6B and cetyltrimethylammonium bromide (CTAB) forms in a weakly acidic medium. However, there has been no report on the formation of a ternary complex with a quaternary complex of alanine 6B . In this paper, a systematic study of rare earth and blue 144B,
