- W2386743870 abstract "The polymerization reaction of activity components in coke-oven C9 by chloroaluminate ionic liquid as catalyst was examined. And the polymerization reaction mechanism and the influences of impurities, such as phenolic and basic nitrogen compounds in coke-oven C9 fraction, on the polymerization catalytic activity of [Et3NH]Cl-2AlCl3 catalyst were studied by the pyridine and acetonitrile adsorbed FT-IR. The polymerization reaction conditions of initial temperature and dosage of the catalyst were also investigated. The results show that the phenolic and basic nitrogen compounds are poisonous substances which lead to reducing the ionic liquid catalytic activity, therefore, they must be removed. The Brnsted acid of [Et3NH]Cl-2AlCl3 exhibits a high catalytic activity used in the polymerization reaction of benzofuran with indene. Under the reaction conditions of ionic liquid addition 1.0%(ω), air pressure, and initial reaction temperature 45℃, the reaction is completed in 10 s, and the conversation rates of benzofuran and indene are almost up to 100%, and high quality benzofuran?indene resin with softening temperature over 130℃ and color number 2# is obtained." @default.
