摘要: Homologue and isomer patterns of polychlorinated dibenzo-p-dioxin (PCDD) dibenzofuran (PCDF) in CuCl2-catalyzed formation were studied an isothermal flow reactor using a distribution 20 phenols as measured municipal waste incinerator (MWI) exhaust gases. A mixture was synthesized used reactants for this study because are known to be key precursors the PCDD/F. Experiments conducted at 400 degrees C. The 92% nitrogen (N2) 8% oxygen (O2) carrier gas. PCDD/F homologue with (DD) (DF) obtained from phenols. DF+PCDF favored over DD+PCDD formation. major groups formed non-chlorinated DD DF, fraction decreased degree chlorination. distributions almost constant. Phenol lower chlorinated present high amount played important role congener distributions. results presented here can characteristics or fingerprints attribution reaction
