Qingdao University of Science and Technology
Research into green chemistry and catalytic conversion represents a key direction for sustainable development in the field of chemical engineering, and the purity of solvents directly determines the efficiency and environmental friendliness of green synthesis. In research into green chemistry and catalytic conversion, researchers have long been troubled by impurities in solvents: Impurities in traditional green solvents reduce catalytic conversion efficiency and increase the formation of by-products. This not only compromises the environmental sustainability of the reaction but also raises raw material costs. Consequently, many green chemical research projects—such as biomass conversion and the utilisation of CO₂—have struggled to progress due to solvent-related issues, becoming a bottleneck that hinders breakthroughs in research.
To address this challenge, the School has introduced a solvent purification system developed by Beijing Yifeng Technology Co., Ltd. This system is designed for green solvents such as ethanol, isopropanol and carbonates, featuring an optimised impurity removal process that thoroughly eliminates impurities from the solvents, ensuring their purity meets the stringent requirements of green catalytic conversion. The system employs an energy-efficient design that enables the recycling of solvents, significantly reducing solvent consumption and environmental impact, whilst also providing automated continuous liquid supply to enhance experimental efficiency.
The commissioning of the Yifeng solvent purification system has injected new momentum into the institute’s green chemistry research. The purified solvents have significantly improved catalytic conversion efficiency and substantially reduced by-products, thereby enhancing both the environmental sustainability and economic viability of the reactions. Challenges in green synthesis previously caused by solvent impurities have been successfully resolved. Researchers are now able to focus on optimising catalytic systems and developing green synthetic routes, successfully achieving breakthroughs in numerous green chemical technologies, including biomass conversion and the resource utilisation of CO₂. This provides vital support for sustainable development in the chemical engineering sector. Yifeng Technology empowers green research through technology, helping the principles of green chemistry take root and enabling the university to remain at the forefront of exploration in the field of green chemical engineering.
