摘要
An analysis of the literature data on the heat capacity of aqueous low-concentration solutions of tert-butanol at several temperatures showed that the heat capacity peak in this concentration region was largely related to critical concentration fluctuations close to the binodal, which appeared because of microlayering on the network of H-bonds in solutions of hydrophobic nonelectrolyte molecules.
