Title: Methods and systems for the formation of cyclic carbonates

Patent ·
OSTI ID:1166758
; ; ; ;

Described herein are inventive methods for synthesis of cyclic carbonates from CO.sub.2 and epoxide. In some embodiments, the methods are carried out in the presence of a catalyst comprising an electrophilic halogen. In some embodiments, the methods are carried out in a flow reactor.
