Disruption of the self-molecular association of pentanol in binary mixtures with alkylbenzoates: a dielectric relaxation spectroscopy study

Abstract

A dielectric relaxation study of binary mixtures of associative pentanol isomers and non-associative alkylbenzoates at different mole fractions revealed that the effective dipole rotates faster in the alkylbenzoate rich region.

Dielectric, Volumetric, Refractometric, and Excess Properties of (Cycloalkanone + Pentanol Isomers) Systems at T = 298.15 K

“…Except for weakly self-associated tert -pentanol, all the studied pentanols are strongly self-associated compounds through the intermolecular specific and nonspecific attractions. The high polar compounds such as CPO or CHO can disturb or break the alcohol’s associated structure on the mixing process. − …”

A dielectric and spectrophotometric study of the tautomerization of 2-hydroxypyridine and 2-mercaptopyridine in water

“…35 Dielectric Relaxation Spectroscopy (DRS) is a tool to study the structure and dynamics of the complex liquid uids whose properties are dominated by hydrogen bonding and is adequate for an investigation of hydrogen bond rearrangement dynamics. DRS has been widely applied for investigating pure solvents, [36][37][38][39][40][41][42] solvent-solvent mixtures, 43 super-cooled, and glass-forming liquids, [44][45][46][47][48] water-organic compound mixtures, [49][50][51][52][53][54][55][56][57][58][59][60] and electrolyte solutions. In-depth knowledge in hydrogen bond is required to understand the nature of molecular interactions taking place in biological activities; enzyme catalysis, drug synthesis and chemical and electrical properties of the material.…”
