Chemical recycling of polycarbonate wastes into bisphenol A by using green
solvent composition (in English)
Polimery 2013, No 4, 292
Polycarbonate contained in waste compact discs (CDs) and digital versatile (video) discs (DVDs) have been chemically recycled into bisphenol A (BPA) — using a ternary solvent system: glycerin, sorbitol, water under conventional heating method. The obtained results show that the mixture of glycerin, sorbitol, water in the ratio 6:3:1 undergoes recycling with high yield within 45 minutes. The recovered BPA was identified by spectroscopic methods and the results were compared with the data corresponding to standard sample.
