Reaction Steps

As the concentration of sulfuryl chloride increases, over-chlorination occurs, i.e., the 2,4,5-trichlorophenol becomes chlorinated to form more 2,3,4,6-tetrachlorophenol. The 2,3,4,6-tetrachlorophenol present becomes unacceptably high when the ratio of sulfuryl chloride to dichlorophenol significantly exceeds 1.3 to 1.
