Reduction of Bromine Compounds in Oil Produced from Brominated Flame Retardant Plastics via Pyrolysis Using a Reflux Condenser
Z. Z. Hlaing, T. Wajima, S. Uchiyama and H. Nakagome
Abstract—In this study, brominated acrylonitrile–styrene– butadiene (Br-ABS) was pyrolyzed at 450°C using a reflux condenser. Br-ABS resins were pyrolyzed in the glass reactor with a reflux condenser, and the reflux condenser temperature was varied from 150°C to 200°C to reduce the bromine compounds in the oil produced via pyrolysis. The components of the oils produced from Br-ABS via pyrolysis at 450°C included isopropyl alcohol, toluene, ethylbenzene, styrene, cumene, propylbenzene, αΎ³-methylstyrene, butylbenzene, and other aromatic compounds. The bromine compounds were 2-bromophenol, 3-bromophenol, and 2,4-dibromophenol. With increasing reflux condenser temperature, the yield of oil decreased, the yield of residue increased, and the yield of bromine compounds decreased. Hence, the concentrations of bromine compounds in oil obtained without a reflux condenser were higher than that obtained with a reflux condenser, which indicates that the reflux condenser is effective for reduction of bromine compounds in oil produced via pyrolysis.
