Abstract:
The present invention provides a catalyst system for producing cyclic carbonates comprising:
a pre-catalyst, which is BiCl3 having amounts in the range from 5 to 10% by weight of silica support;
a compound having formula (I)
wherein:
Y is selected from bromide (Br−) or iodide (I−);
R1, R2, and R3 are methyl group or R1, R2, and R3 are taken together to form a heteroaryl ring having formula (II)
and
a silica (SiO2) support.
