The dissolution rate of bagasse cellulose in LiCl/DMAc solution actived by thermal DMAc and KMnO4 were compared. The effects of several factors on the dissolution rate were discussed, including cellulose concentration, LiCl concentration, solution temperature, and disssolving time. The results showed that the dissolution rate of bagasse cellulose actived by KMnO4 is higher than that actived by thermal DMAc. The dissolution rate increased with the increasing of LiCl concentration, solution temperature, and dissolving time, respectively. |
