摘要：

The HCl-catalysed delignification of Eucalyptus globulus wood by aqueous acetic acid was optimized in accordance with an incomplete 3x3x3 factorial design with HCl concentration (0-0.05%), temperature (120-160 degrees C) and reaction time (1-4h) as independent variables and pulp yield, pulp lignin content and pulp potential glucose content as dependent variables. Empirical equations derived from the results satisfactorily predict the influence of the independent variables on these characteristics of the delignification process and the delignified pulps.
