The heats of immersion Q{sub i} of microporous carbon and nonporous carbon black in n-alcohols and n-alkanes are equal for molecules with the same number of carbon atoms n and increase linearly with an increase in n. The structure of the liquid-solid interface is similar for two types of liquids: only the hydrocarbon radicals are closely adjacent to the hydrophobic carbon surface, and the OH alcohol groups are directed toward the bulk of the adsorbate. The heat of immersion Q{sub is} of the alcohols and alkanes per unit carbon surface is 120 + n, mJ/m{sup 2}. The Q{sub is} values for the alcohols and alkanes with n varying from 1 to 16 can be used for the determination of the specific surface area s of any nonporous or mesoporous carbon adsorbent: s = Q{sub i}/Q{sub is}.
