  摘要：

  Dimer 9, which-is;representative of diaryl methane structures reported present in residual lignin, was reacted with aqueous chlorine at 50 degrees C. The major product was identified as the tetrachloroquinone dimer 13 (x = 2, y 2).; Similar reaction of the tetrachlorocatechol dimer 12 with aqueous chlorine gave a mixture of the tetlachloroquinones 15 and 16. When the mixture of the quinones was reacted with 2.5% sodium hydroxide, an intramolecular oxidation-reduction (Cannizzaro) reaction with the simultaneous loss of two chlorine atoms occurred as the main reaction. The products, 21, were characterized as having a chlorine-free muconic acid lactone group attached to a dichlorocatechol. A third product 17 from the reaction with sodium hydroxide appeared to result from simple displacement of the two chlorine atoms in the quinone ring of 15 by hydroxyl groups. The results provide some clarification of the reactions occurring during classical chlorine bleaching. The results are also in agreement with literature reports concerning some of the-structural characteristics of the high mass material.
