功能化碱性离子液体催化降解木质素合成香兰素

Synthesis of Vanillin by Degradation of Lignin in the Presence of Functional Basic Ionic Liquid

研究了功能性碱性离子液体催化降解木质素,同传统的NaOH溶液降解结果比较,得到了较高的木质素降解率和较简单的降解产物组成。进行了反应条件的优化,得到较优的反应时间、反应温度和催化剂用量。超声辅助降解证明利用超声前处理可以支持降解过程。

The degradation of lignin catalyzed by functional basic ionic liquid was investigated.Higher conversion of lignin and simpler degradation product composition were obtained in the presence of basic ionic liquid,instead of traditional NaOH solution.The reaction conditions were optimized.Ultrasound-assisted test proved that the ultrasound pretreatment favored the degradation process.
