摘要: Microwave assisted glycolysis of polyurethane (PU) flexible foam wastes at atmospheric pressure in “split-phase” condition is reported. Glycerin, sodium and potassium hydroxides were used as glycolysing agent catalysts, respectively. Decomposition dissolution the was studied different reaction condition. Results showed successful polyol recovering short time comparison with conventional heating method. Finally, recycled identified by FT-IR, 1HNMR 13CNMR spectroscopy methods, being compared virgin one.
