Conclusions

By gas chromatograph-mass spectrometry, mass spectrometry, and liquid chromatography, the following possible contaminants in isophthaloyl chloride have been identified: isophthalic acid, isophthaloyl mono acid chloride, chloroisophthaloyl chloride (a mixture of isomers), chloroisophthalic acid, monochloroisophthaloyl chloride, (3-dichloromethyl)benzoyl chloride, (3-trichloromethyl)benzoyl chloride, 3-formylbenzoyl chloride, isophthalic anhydride bis(acid chloride), isophthalic chloroisophthalic anhydride bis(acid chloride), and chloroisophthalic anhydride bis(acid chloride).

A calibration of chromatographic columns for determining 4-monochloroisophthaloyl chloride, 4-chloroisophthaloyl chloride, and 4-chloroisophthalic acid has been carried out.
