用Dimroth-Reichardt E（T）（30）甜菜碱染料、4-硝基苯甲醚、4-硝基苯胺和N，N-二乙基-4-硝基苯胺研究了2-甲基丙唑与正己烷、苯、异丙醇、乙醇和甲醇的二元混合物在30 ℃下在整个溶剂组成范围内的优先溶剂化。一个理论方程，它考虑到溶质-溶剂和溶剂-溶剂的相互作用已成功地采用相关的实验值与溶剂组成。指示剂已用于计算混合物的Dimroth-Reichardt E（T）（30）和Kamlet-Taft pi*、α和β溶剂化变色参数。
The Dimroth-Reichardt E(T)(30) betaine dye, 4-nitroanisole, 4-nitroaniline and N,N-diethyl-4-nitroaniline have been used to study preferential solvation in binary mixtures of 2methylpropan-Zol with hexane, benzene, propan-2-ol, ethanol and methanol at 30 degrees C over the whole range of solvent compositions. A theoretical equation which takes into account the solute-solvent and the solvent-solvent interactions has been successfully employed to correlate the experimental values with solvent composition. The indicators have been used to compute the Dimroth-Reichardt E(T)(30), and Kamlet-Taft pi*, alpha and beta solvatochromic parameters of the mixtures.
