Infrared spectra of water dissolved in benzene and n-hexane at temperatures in the 373-573K range and at pressures in the 100-200 bar range have been measured. The absorption intensities of the OH stretching bands of HDO increase greatly with increasing temperature, indicating increase in solubility of water in the hydrocarbons. Furthermore, the band shapes exhibit remarkable temperature dependence. This is due to increase in hydrogen bonded species relative to a monomeric species with increasing temperature. Concentrations of HDO in the hydrocarbons have been estimated from the observed intensities by use of an empirical relationship between molar absorption intensities and band peak wavenumbers for hydrogen-bonded HDO.
