Joint Development of Catalytic Technology Using Carbon Dioxide and Silicon Compounds

Tokyo, Japan—Tosoh Corporation and National Institute of Advanced Industrial Science and Technology (AIST) have jointly developed catalytic technology to synthesize diethyl carbonate, a raw material for polycarbonates and polyurethanes, using carbon dioxide (CO2) and a silicon compound as raw materials.

The project team discovered a catalytic reaction that synthesizes diethyl carbonate from CO2 and the silicon compound (tetraethoxysilane). Because the reaction does not produce water as a by-product, it extends catalyst life and heightens reaction efficiency. Commercializing this technology is expected to contribute to a carbon recycling society where CO2 becomes a resource for reuse. The research findings were presented in the online bulletin of industry journal ChemSusChem, published by Chemistry Europe, on November 24, 2020.

To drastically reduce CO2 emissions from fossil fuel use, the need to develop carbon recycling technologies has increased. These technologies need to recover and reuse CO2 as a raw material for application in various products.

On June 7, 2019, the Japanese Ministry of Economy, Trade and Industry’s Agency for Natural Resources and Energy published The Roadmap for Carbon Recycling Technologies. The agency supposes oxygen containing compounds, such as polyurethanes and polycarbonates, as examples of the reuse of CO2 in raw materials.

Tosoh and AIST undertook collaborative research into developing catalysts for reaction of low-cost, low environmental impact, renewable raw materials with CO2 to manufacture oxygen containing chemicals. In this project, the team developed the technology to synthesize diethyl carbonate from CO2 and silicon compound by using specific catalysts.

The research project team is working to improve its technology’s reaction and catalyst to establish the lowest-cost, most energy- and resource-saving production method possible. It is also applying itself to solving any technical problems to ensure the technology’s practical application, including scaling up reaction volume. We aim for the practical application of its technology by around 2030.
