Abstract
A method for the synthesis and purification of mono-, di- or trichlorinated bisphenol A compounds of specified formula comprises chlorinating bisphenol A and then separating the compounds by chromatography. A method for the synthesis and purification of mono-, di- or trichlorinated bisphenol A compounds of formula (I) comprises chlorinating bisphenol A and then separating the compounds by chromatography: R1 is Cl and R2-R4 are H for mono chlorinated bisphenol A R1 and R3 are Cl and R2 and R3 and R4 are H for di chlorinated bisphenol A and R1-R3 are Cl and R4 is H for trichlorinated bisphenol A. An Independent claim is also included for the compounds of formula (I).
