摘要
Meta-chlorophenols useful as intermediates in various organic syntheses are prepared by selectively catalytically hydrodechlorinating a polychlorophenol in liquid phase in an acid solvent medium which is at least partially aqueous, in the presence of a Group VIII noble metal catalyst and at least one Group 1b to 5a heavy metal, said polychlorophenol bearing chlorine substituents in both the meta- and ortho- and/or para-positions.
