Abstract
In this paper, the oxyen delignification process of pinus massoniana prehydrolysis sulfate pulp was studied, the mechanism of oxy-en delignification of prehydrolysis sulfate pulp was discussed based on the comparison of oxyen deligrufication of prehydrolysis sulfate pulps at different prehydrolysis degree with oxyen delignification of KP pulp. The optimal conditions of oxygen delignification of pinus massoniana prehydrolysis sulfate pulp was found that the dosage of alkali 3% , temperature 100*0 .reaction time 60 min, oxygen pressure between 0. 5 Mpa and 0.6 Mpa, MgSO4 charge 0.2%. The oxyen delignification rate of prehydrolysis sulfate pulp was higher than that of KP pulp, and increased linearly with reaction time of prehydrolysis,but viscosity reduction rate was lower than that of KP plup. The infrared spectra analysis indicated that the removal of guaiacyl during oxyen delignification of prehydrolysis sulfate pulp was more than thai of KP pulp, and relative intensity decrease of carbohydrate absorption peaks during oxyen delignification of prehydrolysis sulfate pulp was less than that of KP pulp.关键词
