Green Aprotic Solvent

绿色化学侧重于用良性替代品替代有害化学品，降低对环境和人类健康的风险。生物基化学品寻求用可再生生物质生产的化学品取代目前从石油化工产品中提取的化学品。REACH（化学品注册、评估和授权）等政策通过限制危险物质的使用，在某些情况下甚至完全禁止使用危险物质，确保对人类健康的高度保护。REACH和其他立法可能会使一些非质子溶剂在发达国家难以或不可能使用。Circa Sustainable Chemicals正在开发一种可以在商业水平上生产的更环保的溶剂。

Green Chemistry focuses on replacing hazardous chemicals with benign alternatives, lowering the risk to the environment and human health. Bio-based chemicals seek to replace current chemicals derived from petrochemicals with chemicals produced from renewable biomass. Policies such as REACH (Registration Evaluation and Authorisation of Chemicals) ensure a high level of protection of human health by restricting use of dangerous substances and in some cases, banning them altogether. REACH and other legislation could make the use of several aprotic solvents difficult or impossible to use in developed nations. Circa Sustainable Chemicals is developing a greener solvent that can be produced at commercial levels.
