A research team from Seoul National University's School of Chemical and Biological Engineering led by Professor Jae-Yun Ryu has significantly improved the efficiency of synthesizing plastic raw materials through local pH control around electrodes.
Key points
•Seoul National University research team boosts plastic raw material synthesis
•Develops oxygen-based lactone and epoxide synthesis without peroxides
•Increases target product selectivity from 16% to 97%
The team developed a technique to synthesize lactone and epoxide without using peroxides, relying on oxygen and electricity, while adjusting the local pH near the electrode. This method greatly enhanced the selectivity of target products from about 16% to 97%, boosting plastic raw material production efficiency.
By optimizing reactor design to control electrode spacing and electrolyte flow, the researchers achieved a substantial increase in the desired product's selectivity. This breakthrough is crucial for producing lactone and epoxide, which are essential raw materials for plastics and precision chemicals.
The findings were published in the international journal 'Journal of the American Chemical Society,' offering new design methods for organic electro-synthesis that could lead to commercial applications.
