由于越来越多的健康和环境问题以及与挥发性有机化合物相关的经济压力，用更环保或更可持续的溶剂取代挥发性有机化合物正变得越来越重要。生物质衍生溶剂，即生物衍生溶剂，因其具有低毒、可生物降解性和可再生性等优点，是近年来研究较多的一种绿色溶剂。本文综述了生物衍生溶剂在溶剂萃取中的应用，重点介绍了生物柴油和萜类化合物的应用。与传统的VOCs相比，这些生物衍生溶剂的总体性能在萃取率和天然产物萃取的选择性方面是相当的，而对金属的萃取没有发现差异。到目前为止，大多数研究人员都专注于实验室规模的热力学研究。未来的工作需要开发和测试新的生物衍生溶剂，了解动力学性能以及溶剂萃取中试研究。(C)2015年，中国化学工业与工程学会，化学工业出版社。版权所有。
Replacement of volatile organic compounds (VOCs) by greener or more environmentally sustainable solvents is becoming increasingly important due to the increasing health and environmental concerns as well as economic pressures associated with VOCs. Solvents that are derived from biomass, namely bio-derived solvents, are a type of green solvent that have attracted intensive investigations in recent years because of their advantages over conventional VOCs, such as low toxicity, biodegradability and renewability. This review aims to summarize the use of bio-derived solvents in solvent extraction applications, with special emphasis given to utilization of biodiesels and terpenes. Compared with the conventional VOCs, the overall performance of these bio-derived solvents is comparable in terms of extraction yields and selectivity for natural product extraction and no difference was found for metal extraction. To date most researchers have focused on laboratory scale thermodynamics studies. Future work is required to develop and test new bio-derived solvents and understand the kinetic performance as well as solvent extraction pilot plant studies.
