Abstract
A method for the separation and identification of mixtures of substituted phenyl N-methylcarbamates by gas-liquid chromatography with thermal conductivity detector was described. By the combination of two operating conditions, mixtures of seven phenyl N-methylcarbamates could be mutually separated. It was confirmed that 3, 4-dimethylphenyl N-methylcarbamate was converted to 3, 4-dimethylphenol during the operation with gas chromatography. This technique should be useful for analysis of pesticide formulation and residue analysis.
