Abstract

Cyrene, or dihydrolevoglucosenone (DHL), is a biobased and biodegradable solvent that can be produced in two steps from cellulose. It has properties similar to dipolar aprotic solvents such as NMP and DMF, both of which raise significant concerns regarding environmental and human health. As such, dihydrolevoglucosenone offers a promising alternative. The use of this sustainable solvent enhances the environmental profile of chemical reactions. However, target compounds synthesized in dihydrolevoglucosenone are mainly purified using an aqueous workup, leading mostly to the disposal of DHL in an aqueous waste stream. This study focuses on recovering dihydrolevoglucosenone through back-extraction processes.

Cyrene 或二氢左旋葡萄糖烯酮 (DHL) 是一种生物基可生物降解溶剂，可通过两个步骤从纤维素中生产出来。它具有与 NMP 和 DMF 等双极性非亲和性溶剂相似的特性，而这两种溶剂都引起了人们对环境和人类健康的极大关注。因此，二氢左旋葡烯酮是一种很有前途的替代品。使用这种可持续溶剂可以改善化学反应的环境状况。然而，在二氢化左旋葡烯酮中合成的目标化合物主要使用水性工作法进行纯化，这导致 DHL 大都被丢弃在水性废物流中。本研究的重点是通过反萃取工艺回收二氢左旋葡烯酮。

期刊介绍： The journal Organic Process Research & Development serves as a communication tool between industrial chemists and chemists working in universities and research institutes. As such, it reports original work from the broad field of industrial process chemistry but also presents academic results that are relevant, or potentially relevant, to industrial applications. Process chemistry is the science that enables the safe, environmentally benign and ultimately economical manufacturing of organic compounds that are required in larger amounts to help address the needs of society. Consequently, the Journal encompasses every aspect of organic chemistry, including all aspects of catalysis, synthetic methodology development and synthetic strategy exploration, but also includes aspects from analytical and solid-state chemistry and chemical engineering, such as work-up tools，process safety, or flow-chemistry. The goal of development and optimization of chemical reactions and processes is their transfer to a larger scale; original work describing such studies and the actual implementation on scale is highly relevant to the journal. However, studies on new developments from either industry, research institutes or academia that have not yet been demonstrated on scale, but where an industrial utility can be expected and where the study has addressed important prerequisites for a scale-up and has given confidence into the reliability and practicality of the chemistry, also serve the mission of OPR&D as a communication tool between the different contributors to the field.
