In this study,C2 H 4 Cl2/TiCl4 was first used as catalyst in the decoloration of C9 fraction which was steamed out in the preperation of petroleum resin.The impurity was examined as olefin by GC-MS analysis.The results showed that C2 H 4 Cl2/TiCl4 had the advantages of small usage and short reaction time in the catalystic reaction.Achromatic,transparent and low-temperated distillation which contains 0.72% olefin was obtained at 50 ℃ for 3 h with reactants components of 0.2% C2 H 4 Cl2 , 1.1% TiCl4 and 0.9% 2,6-dimethyl pyridine.The distillation product was divided into two parts of fraction oil (boiling range:100~140 ℃ and 141 ~ 1 98 ℃).Its composition and quality technical indicators met with standard of rubber solvent oil and paint solvent oil.
