摘要：

Acacia chips cooked at 200-degrees-C for 10 approximately 60 minutes were exploded in a small batch reactor with aqueous solution of ethanol of concentration from 0 approximately 61 wt%. The measurements of pulp yield and Klason lignin content in the exploded pulp indicated that the explosion with aqueous ethanol solution increased the amount of holocellulose retained. The exploded pulps were then bleached with H2O2 and alkali. Again it was found that more pulp and less lignin remained in the bleached pulp when the chips were exploded with aqueous ethanol solution than were obtained without ethanol.
