Abstract:

Using a palladium on charcoal catalyst, the hydrogenation reactions of CF3CH2Cl, CF3CHCl2, n-C4H9Cl, and sec-C4H9Cl proceeded quantitatively at 250C and are suitable for calorimetric study. The hydrogenation of CH2 CHF, CH2 CF2, CHF CF2, and CF2 CF2 proceeded quantitatively at 120C and the heats of reaction were measured at this temperature. The hydrogenation of these fluoro-olefines at 250C produced considerable amounts of HF which, at this temperature, was very corrosive to the tantalum reaction chamber. Author
