<p><span lang="EN-US">Using the layer wicking method (TLW method) the electron-donor interactions of surface free energy of the organic liquids: benzene (C<sub>6</sub>H<sub>6</sub>), toluene C<sub>6</sub>H<sub>5</sub>CH<sub>3</sub>), and tetrahydrofuran ((CH<sub>2</sub>)<sub>4</sub>O) was determined. <span lang="EN-US">For this purpose the penetration rate measurements of these liquids in the porous layers of silica gel and alumina were performed. </span></span>The obtained values of the
