Apparent molal heat capacities of organic solutes in water. V. aminoalcohols,aminoethers, diamines,and polyethers

Apparent molal heat capacities of 20 organic uncharged compounds in aqueous solution have been determined at 25 and 40°C. The substances studied include mono- and polyfunctional ethers, and bifunctional open-chain compounds like aminoalcohols, aminoethers, and diamines. The results obtained support the presence of interaction between water and the hydrophilic groups –O–, –NH₂, –NH–, and , and evidence indicates that these interactions strongly depend on the molecular structure of the compound containing the functional group.
