开发了一种在温和条件下将二氧化碳固定到固体二氧化碳储存材料（CO2 SM）中的新工艺。展示了胺-乙二醇系统在利用现成的 1,2-乙二胺 (EDA) 和乙二醇衍生物 (EG) 捕获、储存和利用 CO2 方面的新应用。通常，CO2 SM 的分离产率为 28.9-47.5%，然后使用 (13) C NMR、XRD 和 FTIR 进行广泛表征。我们发现，特别是所得的基于聚乙二醇300的CO2 SM（PCO2 SM）产品可以加工成用于CO2储存的稳定片剂； PCO2 SM水溶液在多次循环后表现出显着的CO2捕获和释放能力。最重要的是，从 PCO2 SM 中释放的 EDA 和 PEG 300 被发现可以作为具有纳米层结构的 CaCO3 微粒的多重制备的促进表面活性剂。
A new CO2 fixation process into solid CO2 -storage materials (CO2 SMs) under mild conditions has been developed. The novel application of amine-glycol systems to the capture, storage, and utilization of CO2 with readily available 1,2-ethanediamine (EDA) and ethylene glycol derivatives (EGs) was demonstrated. Typically, the CO2 SMs were isolated in 28.9-47.5 % yields, followed by extensive characterization using (13) C NMR, XRD, and FTIR. We found that especially the resulting poly-ethylene-glycol-300-based CO2 SM (PCO2 SM) product could be processed into stable tablets for CO2 storage; the aqueous PCO2 SM solution exhibited remarkable CO2 capturing and releasing capabilities after multiple cycles. Most importantly, the EDA and PEG 300 released from PCO2 SM were found to act as facilitative surfactants for the multiple preparation of CaCO3 microparticles with nano-layer structure.
