摘　　要：进行了麦草浆高压、高温H_2O_2漂白的研究,探讨了漂白压力、温度、时间和H_2O_2用量对纸浆白度和粘度的影响。在1.2MPa、125℃下H_2O_2用量4％,纸浆白度可达79.7％ISO,粘度为846ml/g。The hydrogen peroxide bleaching of wheat straw pulp under high pressure and high temperature was studied. The effects of different pressure, temperature, retention time and hydrogen peroxide dosage on the brightness, kappa number and viscosity of the pulp are investigated. The pulp with brightness of 79.7%ISO and viscosity of 846mL/g can be obtained in single stage bleaching under the condition of 4% H2O2, 1.2 MPa and 125℃ within 60min.
