摘要
The solubility of oleic and linoleic acids in water was measured in the range from 60 degrees C to 230 degrees C at 15 MPa. The solubility of oleic acid was almost the same as that of linoleic acid in this range, and the solubility of the fatty acids was higher at higher temperature. The logarithm of the solubility of the fatty acids was related to the reciprocal of the absolute temperature by a linear equation with a negative slope at temperatures above 150 degrees C, and the enthalpy of the solution of each fatty acid in the liquid state in water was estimated to be 122 kJ/mol.
