摘要: This paper investigated the reduction of benzo[a]pyrene (BaP) in coal tar pitch by modifying with 1,4-Benzenedimethanol, Divinylbenzene and Trioxymethylene. Coal was modified these Cross linking monomers respectively. The content BaP product determined. results indicated that 48.28% reduced 12% divinylbenzene at 130°C for 3 hours; 66.38% 25%1, 4-Benzenedimethanol 120°C 1 hour; Furthermore, 92.24% 25% trioxymethylene 110°C 0.5~1h. Pure blended trioxymethylene. C13 N.M.R.spectras raw material were determined, mechanism probably including C-alkylation.
