Author(s): Zongyu Liu, Wei Song and Yu DengIn this paper, basic ionic liquid [NH-(C2H4OH)3]+ is synthesized. The effects of cooking temperature and time on pulping process are analyzed based on the changes of lignin quality. Kinetics experiments are carried out under the temperature 80Ã?¢Ã?â??Ã?Æ?, 90Ã?¢Ã?â??Ã?Æ?, 100Ã?¢Ã?â??Ã?Æ?, 110Ã?¢Ã?â??Ã?Æ?, 120Ã?¢Ã?â??Ã?Æ?, respectively. The results indicate that delignification reaction kinetics of basic ionic liquid [NH-(C2H4OH)3]+ cooking rice straw pulping process belongs to first order. The linear regression equation is lnk=10.327-6174.2/T, and its fitting coefficient R2=0.9901. Delignification reaction activation energy is 51.344kJ·mol-1.
