Trichloronitrosomethane. Part I. Physicochemical studies

Abstract

The vapour pressure of liquid trichloronitrosomethane has been measured over the range –20 to +35°, by a static method. The equation obtained is log₁₀p(mm.)=(7·96 ± 0·05)-(1690 ± 14)/T whence the latent heat of vaporisation, the boiling point, and the Trouton constant are calculated to be 7730 ± 65 cal. mole^–1, 59·5 ± 1·0° and 23·0 ± 0·5 cal. deg.^–1. The density and refractive index at 25° are 1·528 ± 0·002 g. ml.^–1 and 1·4446 ± 0·0005. The infrared spectrum of gaseous trichloronitrosomethane has been examined in the region 5000—260 cm.^–1 and some assignments are made. The visible spectrum and the mass spectrum are also reported.
