Chemical degradation of Poly(Bisphenol A carbonate) (PC) is achieved using an easy-to-use organocatalyst, 1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD). Because of increased concern over bisphenol A (BPA) acting as a potent hormone disruptor, proper disposal of waste PC must be conducted to prevent BPA leakage into the ecosystem. Among the many catalysts tested, TBD exhibited the best performance to PC depolymerization. Under mild conditions and low catalyst loading (as low as 1 mol%), PC can be quantitatively degraded into its parent raw material, BPA and Dimethyl carbonate (DMC). To simplify the reaction process, when the product DMC served as a solvent without the auxiliary solvent, excellent depolymerization was observed. The lack of auxiliary solvent reduces the number of chemical components entering the separation process. A group of value-added organic carbonates were successfully synthesized from the PC resin of alcoholysis with other alcohols. |
