The pyrolysis of N-n-alkyl-N, N-dimethyl anilinium bromide was carried out at 250°C in a sealed glass tube and, alternatively, in the flash heater chamber of a gas chromatograph. Both methods gave identical pyrolyzates, i. e., n-alkyl bromide, N, N-dimethyl aniline and N-n-alkyl-N-methyl aniline which were identified with the authentic samples by IR spectroscopy and gas chromatography. The temperature dependences of the pyrolytic reactions of N, N, N-trimethyl anilinium bromide and N-benzyl-N, N-dimethyl anilinium chloride were also investigated. Judging from these observations together with the results of the pyrolysis of benzalkonium salts and alkyl pyridinium salts, which already had been reported, the thermal decomposition reaction of the quaternary ammonium salts was reviewed and the applicability of the pyrolysis gas chromatography to the analysis of cationic surfactants was discussed.
