Solvent Effects on Hydrogen Bonding between Ethyl Methacrylate and 1-Butanol

Abstract

FTIR Spectroscopy / Hydrogen Bonding / 1 : 1 Complex / Solvent EffectThe hydrogen bonding between ethyl methacrylate dissolved in 1-butanol in inert solvents viz., n-heptane, carbon tetrachloride and benzene has been studied using FTIR spectroscopy. Utilizing Nash method the formation constant of the 1 : 1 complexes has been calculated. The formation constant and free energy change values vary with the solvents are observed in the present study confirms the solvent environment may affect the strength of intermolecular hydrogen bond formation between free hydroxyl group of 1-butanol and the carbonyl group of ethyl methacrylate.

FTIR and dielectric studies of molecular interaction between alkyl methacrylates and primary alcohols

“…This observation indicates the formation of 1:1 complex between free hydroxyl group of alcohol and carbonyl group of acrylic ester (i.e.) (O-H Á Á Á Á OQC) [4][5][6][7][8][9][10][11][12].…”

Dielectric Study of Methyl Acrylate-Alcohol Mixtures Using Time Domain Reflectometry

“…The excess inverse relaxation time is defined as (6) where is the excess inverse relaxation time which represents the average broading of dielectric spectra. The information regarding the dynamics of solute-solvent interaction from this excess property is as follows:…”

“…Chaudhari et al 5 reported the dielectric parameters for butyl acetate-alcohol mixtures using the time domain technique. Recently our research group has investigated the complex formation of alkyl methacrylates with proton donors (primary alcohols) using FTIR spectroscopic [6][7][8][9][10][11][12][13][14][15][16] technique. The aim of the present investigation is to study the molecular interaction in methyl acrylate-alcohol mixtures in the microwave region (10 MHz to 10 GHz) with varying concentrations (0% to 100%) using TDR technique for temperatures ranging from 283 K to 313 K. The relaxation behaviors of these mixtures were explained by the Debye model.…”

Relaxation Study of N-Submitted Amides with Alcohol Mixtures by Time Domain Reflectometry

“…There are many studies of the dielectric behaviour of alcohol mixture with structure breaking and structure making [5][6][7][8][9][10][11] . Sivagurunathan et al [12][13][14][15][16] has investigated the complex formation of alkyl methacrylates with proton donors (primary alcohols) in non-polar solvents at 298 K using FTIR spectroscopic method. The complex formation has been interpreted in terms of the association equilibrium constant.…”
