“…3 Excess free enthalpy as a function of the phase composition was used as a measure of the interaction with the support (diatomites and silica gel). The value of adsorptive interaction falls off in the order: furan, thiophene > chloroform > benzene > aliphatic hydrocarbons > CC1 4 , i.e., the interaction solute-solid support is the most pronounced in the case of HC.…”
