Efficient fixation of CO2 into propylene carbonate with [BMIM]Br in a continuous-flow microreaction system

Abstract

Utilization of carbon dioxide (CO2) is of great significance in the development of CO2 absorption and the solution of greenhouse gas effect. Highly efficient conversion of CO2 into cyclic carbonate with green catalysts is essential for the more sustainable expansion of CO2 fixation. Traditional batch reactor is limited by low efficiency, high cost and low security. Meanwhile, continuous flow system showcased a myriad of virtues, including shortening the residence time from hours to seconds, and decreasing reaction temperature, and possessing the nature of easy industrial scale-up. In this paper, a continuous-flow microreaction system was developed to synthesis propylene carbonate (PC) from p..
