Polyhalogenoaromatic compounds. Part XXXVI. Mass spectra of octa- and hepta-chloronaphthalenes

Abstract

Mass spectra of octa- and the two hepta-chloronaphthalenes and hexachlorobenzene are recorded and discussed. Serial losses of chlorine atoms provide the major fragmentation sequence in each case and spectra of all three naphthalene compounds contain peaks due to C₁₀⁺ and C₁₀²⁺ ions. G.I.c.–mass spectrometry was used to separate the components of a commercial product containing polychloronaphthalenes and record their spectra. Some limitations of the use of mass spectrometry for the analysis of polychloro-compounds are discussed.
