Abstract

Nowadays there is a strong urge to replace the fossil-based chemicals and fuels with biobased ones. In this context, the 7th principle of the green chemistry, the Sustainable Development Goals (SDGs) and the recent Safe and Sustainable by Design (SSbD) approach are the main references. Among the various biorefineries, lignocellulosic biomasses represent the most abundant resource to explore. Considering the vast plethora of useful molecules produced from lignocellulosic biomasses, levulinic acid embodies a potential starting material for the preparation of high value-added chemicals. This review explores the preparation of levulinic acid form lignocellulosic biomasses and its further valorization to high-value added compounds (γ-valerolactone, ketals and methyl/ethyl levulinate), considering the current state of the art of the available synthetic strategies, in a life cycle perspective considering the adoption of the life cycle assessment (LCA) methodology.

从生命周期角度看乙酰丙酸生物精炼厂

如今，人们强烈要求用生物基化学品和燃料取代化石基化学品和燃料。在此背景下，绿色化学的第七项原则、可持续发展目标（SDGs）以及最近提出的安全和可持续设计（SSbD）方法都是主要的参考依据。在各种生物精炼厂中，木质纤维素生物质是最值得开发的丰富资源。考虑到从木质纤维素生物质中生产出大量有用的分子，左旋木质素酸是制备高附加值化学品的潜在起始原料。本综述从生命周期的角度，采用生命周期评估（LCA）方法，探讨了从木质纤维素生物质中制备乙酰丙酸，并进一步将其转化为高附加值化合物（γ-戊内酯、酮类和乙酰丙酸甲酯/乙酯）的过程，同时考虑了现有合成策略的技术现状。
