FTIR Study of Hydrogen Bonding Between Acrylic Esters and Alcohols

Hydrogen bonding between acrylic esters and alcohols has been studied in carbon tetrachloride by using the FTIR spectroscopic method. Utilizing the Nash method, the formation constant of the 1:1 complexes has been calculated. The formation constant and Gibbs energy change values vary with alcohol and ester chain length, which suggests that the proton donating ability of 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.
