abstract Eucalyptus globulus and Betula spp kraft pulps were submitted to a D0E1D1E2D2 bleaching stage and the ethyl acetate extracts of D filtrates analysed by GC-MS. In both species, significant amounts of glucuronoxylan-derived chlorinated compounds were detected, particularly in D-0 and D-1 stages, contributing 17 to 34% of the corresponding AOX. The influence of the nature of the glucuronoxylan of these two species in the amount of chlorinated derivatives formed is discussed.
