温和条件下离子液体对木素降解机制研究

Degradation mechanism of lignin with ionic liquids under mild conditions

首次探究了木素在温和条件下经不同离子液体降解机制,降解后的产物用GC-MS进行了鉴定,为研究木素结构提供了理论支持。通过对其产物分析发现,不同的离子液体对木素降解机制不同,降解产物的类型以及含量也都不尽相同。离子液体完全可以作为木素降解的溶剂,如果催化剂等条件合适,可以生产出以木素为原料的一些有价值的化工产品。

The lignin degradation by different ionic liquids under mild conditions was first studied, and these lignin degradation products were identified by GC-MS. It was found through these products analysis, that lignin degradation mech- anism and the degradation product types were different. The different ionic liquids can be used as the solvent for lignin deg radation. If the conditions such as the catalyst were appropriate, some valuable chemical products can be produced by the lignin degradation.
