核磁共振法研究三苯甲烷类酸性染料与非离子表面活性剂的相互作用

Interaction Between Triphenylmethane Acidic Dyes and Non-ionic Surfactant Studied by NMR

研究显色螯合剂和表面活性剂之间的相互作用,对于探讨胶束增溶分光光度法的反应机理是很重要的。等曾用核磁共振和分光光度两种方法研究了非离子表面活性剂OS-20与铬天青S(记作CAS)和磺酸铬青的相互作用,并对作用机理提出了他们的看法。本文用NMR研究了非离子表面活性剂TX-100和乳化剂OP与CAS和漂蓝6B(记作ECAB)

Interactions between triton X-100 and chrome azurol S or eriochrome azurol B are studied by 1H NMR technique. The variant behavior of triphenylmethane acidic dyes in these reactions were due to the difference of hydrophilic-lyophobic equilibrium values.
