Investigation on molecular interaction of glycols in methanol solutions of methylparaben (methyl 4 – hydroxybenzoate) at different temperatures through thermo-acoustical analysis

To determine the nature of interaction of ethylene glycol (EG), propylene glycol (PG), and hexylene glycol (HG) in the methanol solutions of methylparaben, density and speed of the sound of ethylene glycol, propylene glycol, and hexylene glycol in methylparaben–methanol (MePB–MeOH) solutions were investigated at different temperatures (from 293.15 to 308.15 K) and at the pressure, p = 0.1 MPa. The computed density and speed of sound values were...
