摘要：
Depithed sugar cane bagasse was submitted to the acetosolv pulping process in a flow-through pyrex reactor. Five runs were realized in the same experimental conditions, with good reproducibility, as shown by the comparative analysis of nineteen fractions for each run. The average empirical formula of the lignin corresponds to: C9H8.04O2.81(OCH3)0.92 (OH)0.73 phenolic The HPSEC elution pattern shows a two-stage extraction process, which depends on the morphology of the sugar cane bagasse cell wall.
