Yz. Lai et Sp. Mun, THE CHEMICAL ASPECTS OF ACIDIC DELIGNIFICATION PROCESSES .1. ROLE OF ARYL-ETHER HYDROLYSIS IN ASPEN, Holzforschung, 48(3), 1994, pp. 203-206
The significance of aryl-ether hydrolysis in the acidic delignificatio
n of aspen in both water and methanolic systems was evaluated. The hyd
rolysis of beta-aryl ether units. In addition to the non-cyclic alpha-
aryl ethers. was shown to have a direct impact on the initial rapid de
lignification up to about 30 and 60% level for the water and methanoli
c systems. respectively. Further delignification was also affected by
other chemical reactions. e.g. lignin condensation.
