摘要
芳香烃化合物是一类与人类生产生活密切相关的重要有机化工原料。基于石油资源的日益枯竭及其生产过程中带来的环境污染问题,寻找新的合成芳香烃化合物的绿色化学路线成为有机合成领域中的研究热点。呋喃类生物质主要来源于植物系生物质,廉价和分子多样性使其成为合成芳香烃化合物的重要候选原料。通过热催化或低温催化反应,呋喃类生物质与乙烯、丙烯等亲二烯体可进行Diels-Alder环加成和脱水等反应芳构化为芳香烃化合物。以呋喃类生物质为基础的催化反应可高效利用可再生能源,工业应用前景广阔。目前呋喃类生物质催化转化制备芳香烃化合物的研究大部分依赖高温高压的高能耗反应条件,且面临"一锅法"副反应繁杂的问题,例如水解、烷基化、异构化和低聚等。本文综述了基于不同呋喃生物质分子所取得的研究成果和面临的问题,简要介绍Diels-Alder环加成的反应机理,详细讨论催化剂组分、溶剂效应和亲二烯体对反应效率的影响,并对未来基于生物质的芳香烃化合物合成路径进行展望。
As one of the most important renewable chemicals, aromatic compounds are closely related to human production and life. Increasing concerns about diminishing oil resources and the relevant environmental pollution have gradually motivated interests in exploring new green chemistry routes towards aromatic hydrocarbons synthesis. Prized for the low cost and molecular diversity, biomass-derived furans arise as vital candidate raw materials for the production of aromatic compounds in the new century. Through Diels-Alder cycloaddition and the subsequent dehydration, furans could react with enophiles(such as ethylene and propylene) to obtain value-added aromatics including para-xylene. To our knowledge there exist broad industrial application prospects and economic benefits, and the catalytic reation of biomass-derived furans can effectively utilize renewable, abundant, sustainable energy. However, most of the reported catalytic conversion requires elevated temperature and high pressure, and the one-pot method usually results in multifarious and unrestricted side effects, such as hydrolysis, alkylation, isomerization and oligomerization. In this review, we summarize recent developments in the research achievements and issues of aromatic synthesis based on different biomass-derived furan molecules. The mechanism of Diels-Alder cycloaddition reaction is briefly introduced, followed by its influencing factors: catalyst composition, solvent effect and enophile. Then, perspectives and challenges for biomass-based aromatic synthesis are discussed.
