Molecular interactions in alcohol-ethyl methacrylate mixtures

Molecular interaction between alcohols (1-propanol, 1-butanol, s-butanol, t-butanol, 1-pentanol, 1-heptanol, 1-octanol and 1-decanol) with ethyl methacrylate has been studied in n-heptane, CCl4 and benzene at 298 K using FTIR spectroscopic and dielectric methods. The result obtained from both the methods indicates only the existence of most likely 1: 1 complex formation between the alcohol and ethyl methacrylate in these systems. The alkyl chain length of alcohol and the solvent used play a significant role in the strength of hydrogen bond (O-H:O=C) determined on the basis of spectral and dielectric parameters.
