This invention discloses the method to produce|generate an intermediate body in the process of chlorine-dioxide-bleaching reaction， This intermediate body is produced|generated by making a phenolic lignin model react by a chlorine dioxide and the molar ratio 1:8， This production|generation method performs bleaching reaction of a chlorine dioxide instead of the lignin structure of a unbleached pulp using a phenolic lignin model， An excessive quantity of chlorine dioxides are added to a phenolic lignin model at the time of reaction， a phenolic lignin model is consumed completely， and the intermediate body stable in the initial stage of bleaching reaction is produced|generated rapidly. This invention uses a phenolic lignin model and a chlorine dioxide， produces|generates an intermediate body in a simulation bleaching environment， and is a bleaching process of a chlorine dioxide. WHEREIN: In response to the fact that [ reaction initially like a chlorine dioxide and coordination electrochemical reaction ] rapidly， the stable intermediate body is produced|generated， a lignin is fixed to an intermediate body， then an intermediate body dissociates， and， as for a lignin， a lignin begins to be decomposed|disassembled oxidatively. A discovery of an intermediate body provides the theoretical support for the further reduction of the adsorptivity organic halogenated compound (AOX) at the time of bleaching the wastewater of a paper pulp company.
