Abstract The perfluoro. carboxylic acid fluorides prepared by electrochemical perfluorination (ECPF) method were analyzed by gas chromatography/mass spectrometry. Methanol was used to convert the perfluoro. carboxylic acid fluorides into the methyl esters at 60 degrees C. The effects of column length, polarity and film thickness on the separation efficiency were investigated. The KB-1MS capillary column (90 m x 0. 25 mm x 1. 0 mu m) was employed in the GC/MS analysis. The fragmentation patterns and mass spectrometric characteristics of perfluorinated alicyclic acid methyl esters, aliphatic carboxylic acid methyl esters and mono. unsaturated perfluorinated aliphatic carboxylic acid methyl esters were analyzed and deduced from known patterns of perfluoro-organic mass spectrometry. In this work, five perfluoro. carboxylic acid fluorides including two isomers were identified and the perfluorocyclohexylcarboxylic acid fluoride accounted for about 65% of the total perfluoro-carboxylic acid fluorides in the product.
