Chlorinations of p-xylene and chloro-p-xylene with molecular chlorine at 20-21 deg C in the dark and im acetic acid and, second, of p-xylene in nitrobenzene and neat with or without weak catalysts, have been carried out.The results are compared with those obtained for the FeCl3-catalysed chlorinations of p-xylene and chloro-p-xylene and reveal that dichloro derivates (especially 2,3-dichloro-p-xylene) are obtained directly from p-xylene, probably by an addition-elimination mechanism wich occurs in the all media used except for the FeCl3-catalysed chlorination.The direct formation of dichloro derivates from p-xylene, as well as that of trichloro-p-xylene from chloro-p-xylene, is shown by chlorination of an equimolar mixture of 2H10>-p-xylene and chloro-p-xylene.The separation and evaluation of deuteriated and non-deuteriated chloro derivatives are carried out by g.l.c. on capillary columns.
