The Infra-Red Absorption of Phenol and Its Halogen Derivatives in the Region of the Second Overtone of the OH Absorption

Abstract

Orthohalogen and symmetrically trihalogen substituted phenols in the region of the second overtone of the OH absorption show behavior that is similar to that in the region of the first overtone but with increased displacement of the component absorptions. Subsidiary peaks are observed in the region of the second overtone and appear to stand in ordered relation to the principal peaks. In the present work the ortho- and symmetrically trichloro-, bromo-, and iodophenols as well as pentachlorophenol and phenol itself have been studied in carbon tetrachloride solution. The tendency of phenol to associate in a series of polymers has been studied by means of the phenol absorption. Relative to phenol the association of the above-mentioned substituted phenols is small.

Infrared studies on hydrogen bonding interaction between acrylic esters with 1-dodeconal and phenol in carbon tetrachloride

“…Recently our research group has investigated the complex formation of acrylic esters with proton donors (alcohols) in nonpolar solvents using Fourier transform infrared (FTIR) spectroscopy and dielectric methods [3][4][5][6][7][8][9][10]. Kempter and Mecke [11] have determined the formation constant of phenol in carbon tetrachloride for higher associated complexes, and a number of investigators, including Wulf [12], Gordy and Niclsen [13], Luttke and Mecke [14], have made spectrophotometric studies of phenol and a number of substituted phenols in a variety of solvents. In the present study, an attempt has been made to study the hydrogen bonding between the free hydroxyl and carbonyl groups of 1-dodeconal and phenol and acrylic esters (MMA, EMA and BMA) in carbon tetrachloride using FTIR spectroscopy.…”
