| An intriguing sink for exhaust CO2, which is otherwise released into the atmosphere, is the utilization for chemical syntheses. In particular, the incorporation in polymers and other materials produced in large-scale appears attractive. As new technologies are emerging, the direct utilization of CO2 as reagent appears a viable synthetic route. One of reactions becoming feasible is the synthesis of dimethylcarbonate by direct carbonylation of methanol. The reaction is equilibrium limited to about 1% conversion under typical reaction conditions, but can be realized by coupling with an exothermal reaction for removal of the by-product water. The key to the successful development of new catalysts is the activation of CO2 by binding to either basic groups or Lewis acidic functionalities. Dimethylcarbonate is an excellent starting material for polycarbonate synthesis. In the lecture, the emerging technologies for the fixation of CO2 in polymers will be reviewed and discussed. |
