Chemical Synthesis of Lactic Acid from Lignocellulosic Compouds Catalysed by Pb(II) or Al(III)-Sn(II)

Abstract

催化转化自然界中含量丰富且可再生的纤维素类生物质资源制备平台化学品有非常重要的意义。尤其是,在非氢条件下将纤维素转化为与其化学组成类似的乳酸,是纤维素转化中最具原子经济效益的路径之一,然而相关的研究尚十分有限。本篇论文研究了氮气氛下,简单金属离子Pb(II)和离子组合Al(III)-Sn(II)催化纤维素及其单体葡萄糖转化为乳酸反应,主要取得以下结果: 研究发现,简单金属离子Pb(II)可有效地催化纤维素及葡萄糖转化制乳酸。氮气氛下,在463K反应6h后,Pb(II)催化球磨纤维素制乳酸的收率高达70.2%。此外,该体系还可转化未经纯化的真实生物质,如茅草、甘蔗渣和麸皮等,乳酸收率达60%以...The transformation of abundant and renewable cellulose or cellulose-derived carbohydrates into platform chemicals is the key to establishing biomass-based chemical processes. The system that is capable of catalyzing the conversion of cellulose into lactic acid in water without consuming hydrogen is one of the most atom-economic pathways for converting cellulose. At present, research on this field ...学位:理学博士院系专业:化学化工学院_物理化学学号:2052010015367
