Inversion of the Temperature Coefficient of Internal Pressure and Structural Organization of Liquid Phase Systems

Study of the Effects of Temperature and Pressure on the Thermodynamic and Acoustic Properties of 2-Methyl-1-butanol at Temperatures from 293K to 318K and Pressures up to 100MPa

“…Kartsev et al [29][30][31][32] pointed out that the temperature dependence of internal pressure is sensitive to the structural organization of the liquid and reflects the character of the interactions. They showed that the inversion of the temperature coefficient of the internal pressure at atmospheric pressure is characteristic for primary alcohols, i.e., sign reversal from (+) to (−).…”

Temperature and pressure dependences of volumetric properties of two poly(propylene glycol) dimethyl ether lubricants

“…(p/ T) P < 0. Therefore, according to classified from Kartsev et al [52] these PAGs can be considered as non or weakly associated fluids. This tendency is likely due to for weakly associated fluids, cohesive forces decrease when the temperature rises [53].…”

Heat Capacity and Internal Pressure of Cyclopentanol at Pressures up to 100 MPa Determined by the Acoustic Method

“…Kartsev et al [16][17][18][19] noticed that under atmospheric pressure the temperature coefficient of internal pressure is sensitive to the structural organization of the liquid and reflects the character of the interactions. According to the sign of the temperature coefficient of the internal pressure, liquids can be classified as: (a) not hydrogen-bonded for which the temperature coefficient of the internal pressure is smaller than zero; (b) hydrogen-bonded with spatial net of H-bonds for which the temperature coefficient of the internal pressure is greater than zero; (c) associated which characterized inversion of the temperature coefficient of the internal pressure; sign reversal from (+) to (-).…”
