摘　　要：综述了离子液体在纤维素及其衍生物、半纤维素及其衍生物和木质素及其模型化合物降解转化中的主要作用等方面的研究成果与最新进展.认为离子液体是生物质转化过程中常用的溶剂和催化剂.针对不同类型的生物质,离子液体/无机酸或离子液体/金属氯化物(Lewis酸)是目前研究生物质转化催化剂的主流体系.鉴于目前离子液体体系在生物质催化转化应用中存在成本较高、回收困难等问题,提出了未来的研究方向,主要包括:一是合成性能更好的新的离子液体来催化生物质转化;二是开发新的复合催化体系,有针对性地在离子液体中添加一种甚至多种有助生物质溶解或催化转化的添加剂或催化剂;三是开发成本低廉、性能优越、易于回收的离子液体催化体系.The research results and recent developments of ionic liquids in the main role of the degradation and transformation in cellulose and its derivatives, hemicellulose and its derivatives,lignin and its model compounds were reviewed. Ionic liquids were considered to be solvents and catalysts commonly used in biomass conversion processes. For different types of biomass, ionic liquid/inorganic acid or ionic liquid/metal chloride (Lewis acid) was the mainstream system for postgraduate material conversion catalysts.The problems of the current ionic liquid system in the catalytic conversion of biomass were analyzed. The current ionic liquid system had the problems of high cost and difficult recovery in the application of biomass catalytic conversion. It proposed research directions for further research in the future. The main ones were: one was a new ionic liquid with better synthesis performance to catalyze the conversion of biomass;the second was to develop a new composite catalytic system, specifically a converted additive or catalyst was added into one or more kinds of biomass to dissolve or catalyze the ionic liquid;the third was to develop an ionic liquid catalytic system with low cost, superior performance and easy recovery .
