标题:Preparation of azo pigments with low pcb content by coupling in the presence of olefins
发明人：RIEPER WOLFGANG
权利人:HOECHST AG
摘要:The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls. n According to the invention, it has now been found that by addition of water-soluble olefins of the type ##STR1## (R =H, alk or Oalk; X =--COOR 1 , --CONHR 2 or --NR 3 COR 4 ) n in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.
