The implementation of
CO2
capture from flue gases provides an enormous stream of potential raw materials for chemical production. Apart from their application in carbon capture and storage (CCS) technologies, ionic
liquids have attracted considerable interest as tailored catalysts for the conversion of
CO2
to chemical feedstocks [1]. Among all potential products of
CO2,
its conversion into cyclic carbonates via reaction with epoxides has
received the most attention. Despite the fact that a large pool of catalytically active ionic liquids is available for this reaction, examples of the continuous conversion of
CO2
to cyclic carbonates are rare [2]. This lack of ionic
liquid-based continuous flow processes for the conversion of epoxides with
CO2
is surprising, as the liaison of ionic liquids with (supercritical)
CO2
provides an ideal pre-requisite for this purpose. Herein, we present our
investigation towards the use of supported ionic liquids as catalysts for the conversion of supercritical carbon dioxide, which acts both as solvent and reagent, aiming for the continuous production of propylene carbonate
from propylene oxide and carbon dioxide [3].
