Vapor Pressures and Enthalpies of Vaporization of Benzyl Halides and Benzyl Ethers

Abstract

Molar enthalpies of vaporization of seven benzyl halides and seven benzyl ethers have been obtained from the temperature dependence of the vapor pressure measured by the transpiration method. These values and the correlation-gas chromatography method, based on Kovat's index, have been applied for the determination of of three cumyl halides (Cl, Br, and I). The data obtained for of benzyl derivatives have been checked successfully for internal consistency using enthalpies of formation of alkyl halides and alkyl ethers available from the literature.
