化石资源的日益枯竭,能源需求的不断增长以及全球气候和环境的不断恶化,迫使人类不得不寻找能替代化石资源的可再生新能源.近年来,生物质能由于广泛易得、廉价、碳中性等特点获得了世界各国的高度重视并得到飞速发展.以生物质及其衍生物为原料,催化转化制备多元醇更是成为当前国内外化学工作者的研究热点.多元醇作为一种重要的工业原料,可用于合成氢气、液体燃料和化学品.作为自然界最为丰富的生物质,纤维素可以通过催化转化的方法转变为多元醇.本文对纤维素制备山梨醇、异山梨醇、乙二醇、丙二醇的研究进展进行了总结和评述,并结合本课题组的一系列工作提出了纤维素制备多元醇的未来挑战.
The depletion of fossil resources, the growing demand for energy, and the deteriorating global climate and environment have forced human beings to find new and renewable energy sources that can replace fossil resources. In recent years, due to its wide availability, low cost, Sex and other characteristics of the world has been highly valued and get rapid development of biomass and its derivatives as raw materials, catalytic conversion of polyols has become the current domestic and foreign chemical workers research hot spots. Polyols as an important Industrial raw materials, can be used for the synthesis of hydrogen, liquid fuels and chemicals.As the most abundant biomass in nature, cellulose can be transformed into polyols by catalytic conversion.In this paper, cellulose sorbitol, isosorbide, ethylene glycol , The progress of the research on propylene glycol was summarized and reviewed. Combined with a series of work of our group, the future challenges of cellulose in the preparation of polyols were proposed.
