Solvolysis pulping, named for the method of extracting lignin from wood chips using a mixture of cresol and water has been studied as one of the organosolv pulping systems to separate the pulp. In this study, alkalis (NH<SUB>3</SUB>, NaOH) were added in the amount of 0.1-0.2 equivalent to that of cresol used in the cooking to evaluate the time dependences of the degree of delignification and decarbohydration. Both alkalis increased the reaction selectivity of delignification relative to degradation of carbohydrate because of reduced degradation of xylan component in wood.
