The identification and quantitative analysis of organic compounds dissolved in brines circulating through mercury type Cl₂-caustic electrolytic processes were carried out by means of gas chromatograph-mass spectroscopy and gas chromatography. The possibility of a formation of CH₃HgCl by the reactions of HgCl₂ with halogenated organic compounds were also studied at 70℃ in brine (NaCl 300g/l, pH5.8 and 11.8). The results obtained as followed; (1) The dissolved compounds in brines were founds such as CH₃Cl, CH₂Cl₂, CHCl₃, CH₂ ClCH₂Cl, CH₃3Br, CHBrCl₂, and CHBr₃. (2) Among these compounds, especially, contents of CH₂Cl₂, CHCl₃ and CH₂ClCH₂Cl in brines were 0.X ppm order. (3) A substance estimated as CH₃HgCl was scarcely detected at pH11.8 and not detected at pH5.8 by above-mentioned reactions.
