Description

Application

Sulfolane is a polar aprotic solvent that may be used for the complete pyrolysis of cellulose without any polymerization or carbonization side reaction. Sulfolane, in combination with mesitylene, can be used as a solvent in the synthesis of poly(succinimide) (PSI) from L-aspartic acid. It can also be used as a solvent in the synthesis of chlorine-terminated polyethersulfone oligomer, a polymeric activator for nylon 6-polyethersulfone (PES)-nylon 6 block copolymer synthesis.
