Analysis of Binary Mixtures of Tertiary Amines by Measurement of the Decomposition Rates of π-Complexes with Tetracyanoethylene

抄録

A method has been developed for the determination of the fraction of a single species in a binary mixture of tertiary amines, by measurement of the pseudo first-order reaction rates for decomposition of the π-complexes with tetracyanoethylene. The initial absorbances at three wavelengths (u, v and w) and their sum in a simplified complementary tristimulus colorimetry were calculated by a numerical method. The color points of the reaction solution at the initial time were calculated, so that the fraction of as single species in a mixture of tertiary amines could be evaluated.
