Using a CeC>2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective process has CO2 blown at atmospheric pressure to evaporate excess water by-product allowing for a catalytic process that can be used with any substrate with a boiling point higher than water. By combining a Ce02 catalyst with atmospheric carbon dioxide, researchers from Osaka City University, Tohoku University, and Nippon Steel Corporation have developed an effective catalytic process for the direct synthesis of polycarbonate diols without using dehydrating agents. Their method, published in Green Chemistry, does not rely on toxic chemical feedstock like phosgene and carbon monoxide, making it the world’s first high yield “green" reaction system.

To bypass these issues, the research team developed a catalytic process that does not use a dehydrating agent. By focusing on the difference in boiling points between the chemical product/diol and water, the research team predicted a high
