生物质是唯一能替代化石资源转化得到液体燃料及化学品的可再生资源,近年来,催化转化生物质制备各种平台化合物的研究受到了人们越来越广泛的关注。和乙酰丙酸(LA)一样,γ-戊内酯(GVL)也被认为是一种具有广泛应用潜能的新型生物质基平台化合物。目前,人们已经开发出多种催化剂和反应体系用于催化生物质基LA选择性还原制备GVL。根据氢源的不同可将LA制备GVL的途径概括为4种:分别以分子H2、甲酸(FA)、合成气和醇类作为氢源的途径。本文着重从氢源的差异来归纳和总结生物质基LA选择性还原制备GVL的途径及其研究进展,以期为寻找一种高效、经济、环保的GVL合成途径提供一些思路和参考。
Biomass is the only renewable resource that can replace the fossil resource to get liquid fuels and chemicals. In recent years, the research on the catalytic conversion of biomass into various platform compounds has attracted more and more attention. As with levulinic acid (LA), γ-valerolactone (GVL) is also considered as a novel bio-based platform compound with a wide range of potential applications. At present, a variety of catalysts and reaction systems have been developed for the catalytic reduction of biomass-based LA to GVL. According to the different hydrogen sources, the ways of preparing GVL by LA can be summarized as four ways: the molecular H2, formic acid (FA), syngas and alcohols as the hydrogen source. This article focuses on the differences of hydrogen sources to summarize and summarize the ways of selective reduction of biomass-based LA to prepare GVL and its research progress, in order to provide some ideas and references for finding an efficient, economical and environmentally friendly GVL synthesis pathway.
