The Effect of Anthraquinone and Anthrahydroquinone Penetration on Delignification in the Soda Pulping of Norway Spruce

Autor: Peter Sarko, Laurel E. Falk, Carlton W. Dence, Michael I. Berger

Publikováno v: Journal of Wood Chemistry and Technology. 4:35-59

The extent of anthraquinone (AQ) penetration into handcut Norway spruce chips as a function of cooking time was examined through the combined use of 14C-label-led AQ and various wood sectioning techniques. The results indicated that in the initial st
