kamlet-taft参数 Kamlet-Taft参数是一组描述分子溶剂作用的物理化学指标。它由Kamlet和Taft于1976年开发,旨在量化分子溶剂对水合作用的影响。这个参数通常用于描述有机分子在溶液中的化学行为,如离子溶解度、配位化学和反应机理。 Kamlet-Taft参数由三个度量组成,即极性(π)、氢键接受性(α)和氢键给性(β)。其中,π...

The Kamlet–Taft parameters for 25 glycol ethers and their aqueous solutions were measured. Values for the three Kamlet–Taft parameters: the hydrogen-bond donor ability, hydrogen-bond acceptor ability, and the dipolarity/polarizability, as well as the index of refraction, were determined for each...
The Kamlet-Taft solvent parameters of solvate ionic liquids (SILs) prepared from lithium salts with glyme and glycol ligands are determined. The dipolarity/polarisibilities (pi*) are high, similar to those found in conventional ionic liquids. The H-bond basicities (beta) depend strongly on the...
