Abstract

Experimental dependence of viscosity of binary systems of water - tetrahydrofuran, water -
acetonitrile, hexane – tetrahydrofuran on the volume fraction of modifiers, depending on temperature,
were determined. The thermodynamically invariant description of the experimental isotherms of viscosity
of binary liquid system, used in HPLC as mobile phase, was proposed
