Assessment of Molecular Interactions of 4-Ethyl Thiocarbamidophenol on Acoustic Parameters Base

Acoustic parameters assessment significantly able to disclose molecular and intermolecular interaction briefly. These parameters measured more significant by ultrasonic interferometer. Present research scheme concern to measurements of ultrasonic velocity and density for solutions of 4-ethylthiocarbamidophenol (ETP) at different molar concentrations (i.e. 0.1M, 0.075M, 0.050M and 0.025M) and 300 K, in 70% compositions of ethanol-water mixtures. These determinations sustain estimation of adiabatic compressibility (β ), apparent molal compressibility (k), apparent molal volume (v), intermolecular free length (Lf), relative association (RA) and specific acoustic impedance (Z). These properties were help to know about solute-solute and solute-solvent interactions in solvent. Internal structure and molecular association can be possible to understand through current investigation.
