Molecular interaction studies of acrylic esters with 1-alcohols

Hydrogen bonding between 1-alcohols and acrylic esters in n-heptane has been studied by FTIR spectroscopic method. The formation constant of the 1:1 complexes has been calculated using Nash method. The values of formation constant and free energy change vary with alcohol and ester chain length, which suggests that the strengths of the intermolecular O-H---O=C bonds are shown to be dependent on the alkyl group of acrylic esters and the 1-alcohols and the results shows that the proton donating ability of I-alcohols is in the order: 1-propanol < 1-butanol < 1-pentanol and the accepting ability of acrylic esters is in the order: methyl methacrylate < ethyl methacrylate < butyl methacrylate.
