Synthesis of cyclic carbonates based on diglycidyl ether of bisphenol S by quaternary ammonium salts
We compare the structures of diglycidyl ethers as catalysts and investigate the role of cation and anion of quaternary ammonium salts in preparing diglycidyl ether of bisphcnol S (DGEBS) and cyclic carbonates. The synthesis of cyclic carbonate has been performed by the reaction of carbon dioxide with DGEBS in the presence of quaternary ammonium salts under atmospheric pressure.
