Abstract

Abstract: In this study, C ₂H₄C l ₂/ T i C l ₄first used as catalyst in the decoloration ofC₉ 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 C ₂H₄C l ₂/ T i C l ₄ 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% C ₂H₄C l ₂, 1.1% TiCl₄and 0.9% 2,6dimethyl pyridine. The distillation product was divided into two parts of fraction oil (boiling range: 100~140 ℃ and 141~198 ℃). Its composition and quality technical indicators met with standard of rubber solvent oil and paint solvent oil.
