Description
技术领域
本发明涉及糠醛类衍生物脱羰反应的方法,具体是一种使用双齿膦配体聚合物负载钯催化剂催化糠醛类衍生物脱羰反应的新方法。
背景技术
糠醛衍生物是现代生物燃料生产的重要中间体之一。为了建立可持续的能源系统,有效利用来自木质纤维素生物质的可再生碳水化合物如5-羟甲基糠醛(HMF)、乙酰丙酸(LA)、糠醛等生物原料生成化学品和燃料是非常有意义的工作。长期以来,人们使用费托合成和发酵等方法将生物质原料转化成化学品或燃料。同时,鉴于5-羟甲基糠醛等的特殊结构,脱羰反应也是一种潜在的将生物质原料直接转化成化学品或燃料的路径。自1965年,Tsuji和Ohno发现醛类物质可以在当量的铑催化剂催化下生成相应的烃以后,人们对脱羰反应的进行了不断发展,铑、钌、铱、钯等贵金属也逐步被人们发现能够对醛类物质选择性脱羰。
近年来,一种将糠醛类衍生物尤其是5-羟甲基糠醛化合物直接脱羰转化为一系列有用的分子引起了人们的注意,均相催化的5-羟甲基糠醛脱羰反应蓬勃发展,由于均相反应的限制,参与反应的催化剂和配体难以被分离出来循环使用。2013年中国科学技术大学傅尧教授发展了一种用SBA-15介孔二氧化硅负载钯碳催化剂催化糠醛脱羰反应的新方法(ChemSusChem,2013,6,1348),这是目前仅有的一例多相催化5-羟甲基糠醛脱羰反应的例子,该反应在反应时需要大量分子筛作为反应辅助剂才能达到较高产率,且反应适应性相对狭窄,SBA-15介孔二氧化硅载体制备较为复杂且昂贵,反应所需时间较长,限制了该反应的工业化普及。
糠醛及其衍生物可直接通过酸催化木糖脱水得到,木糖在农产品的废弃部分中(例如玉米的穗轴、秸秆、棉桃的外皮)含量非常高。因此,如何将糠醛等易得的生物原料转化为更加有用的化工精细产品变得举足轻重。而由于糠醛衍生物的高反应性,如何定向地把糠醛转化为四氢呋喃等化工原料一直是现代能源研究的热点和极具战略意义的课题。基于此,高效的脱羰反应无疑是一个有效的转化路线。
