Dependence of surface tension of near-boiling non-associated liquids on their molar volume and some critical constants

The equation proposed for near-boiling non-associated liquids describes a n ew functional dependence of their surface tension on such physico-chemical characteristics as: critical volume, critical temperature and molar volume at the temperatures which are near their normal boiling points. It is shown that, in the case of some low-boiling liquids, possessing small molecules, this equation can be used for the adequate calculation of surface tension at different temperatures in the liquid phase.
