Dechlorination of pentachloropyridine catalyzed by Zn/Ag bimetal particles was studied in this workThe effects of initial pH of the system
amount of catalyst and reaction temperature on the reaction were studiedThe results showed that the zinc powder could be used to reductively dechlorinate pentachloropyridine to tetrachloropyridine with its yield about 20%Under the catalytic effect of silver
the dechlorination efficiency of pentachloropyridine was greatly improvedWhen the initial pH was about 5
the concentration of silver nitrate was 10 g·L-1
the yield of tetrachloropyridine could be above 60%The reaction took place on the bimetal surface in a first order reaction
