Abstract Carbamate insecticides injected into a gas-liquid chromatograph react with trimethylanilinium hydroxide to give derivatives that have good gas-liquid chromatographic properties. The substituted phenyl N-methylcarbamates give methoxy derivatives by this procedure. Chromatographic response was linear with increased concentration for the synthetic standard and the on-column methylation products of the examined substances. The standards obtained were identified by ultraviolet and infrared absorption spectroscopy, as well as by nuclear magnetic resonance and mass spectral analysis.
