微波辅助离子液体溶解木质素的研究
Solubility of Lignin in Ionic Liquid by Assistance of Microwave Energy
摘要
Abstract
Five phosphite-based ionic liquids were synthesized, characterized, and used to dissolve lignin under oil bath and microwave heating. It was found that ionic liquid 1, 3-dimethylimidazolium phosphate [ Mmim ] DMP had good solubility performance, and the solubility of lignin was 60. 0g at 55℃for 30 min. The chemical structure, morphology and crystalline of re-generated lignin from microwave treatment were characterized by FT-IR, SEM, and XRD. The results indicated that the structure of re-generated lignin was unchanged, and the particle had good dispersity and strong diffractive feature. On the other hand, ionic liquid[ Mmim] DMP had good reusability. When 100 g[ Mmim] DMP was reused for five times, its recovery capacity and lignin solubility were 97. 0 g and 57. 8g, respectively.关键词
