Brief description, advantages, further prospects for application.

It is known that transport properties (viscosity, thermal conductivity) are fundamental characteristics, on the basis of which calculations are made when introducing and designing working media as energy-chemical technological processes.

Knowledge of these properties is outstanding for designing chemical process equipment.

In addition, these properties are a direct source of information about the parameters of pair potentials of intermolecular interaction.

Experimental methods used to determine transport properties are laborious (requirements for analysis, purity of reagents, etc.) and cost, and are not applicable to large molecules. The properties of binary mixtures are determined by modeling phase equilibria, since it is binary mixtures that are the most widely used working bodies of chemical-technological devices.

DQSРR based on the simplex representation of the molecular structure has a number of advantages over foreign analogues and has shown itself well in modeling such thermodynamic properties as critical properties (temperature, pressure, volume) and other virial coefficients.

An approximate result of this work will be directed to a wide range of specialists with an expert system for predicting the transport properties of organic substances of various structures and parameters of intermolecular interaction potentials.
