| titleOfInvention | Method for converting low-carbon olefin into isooctene by catalyzing low-carbon olefin with chemically immobilized Br phi sted acidic ionic liquid |
| abstract | The invention provides a chemical immobilization method A method for converting low-carbon olefin into isooctene by using acidic ionic liquid as catalyst. The chemical immobilization The acidic ionic liquid takes micron-sized resin particles which contain halogen X-I, Br or Cl and are within the range of 0.50-2000 mu m as a carrier material, is chemically modified by an N heterocyclic compound, is linked with sulfonate functional groups through covalent bonds to form N heterocyclic modified sulfonate ampholytic salt resin particles, and is finally protonated by sulfuric acid or phosphoric acid solution to prepare the chemically immobilized resin Acidic ionic liquid applied to catalyzing low-carbon olefin isobutene to synthesize a dimerization product isooctene product in a high-selectivity manner and chemical immobilization The dosage of the acidic ionic liquid accounts for 1.0-15 wt% of the mass of the isobutene, the reaction temperature is 70-120 ℃, the reaction time is shortened to be within 50min, the highest conversion rate of the isobutene reaches 99%, the highest selectivity of a dimerization product is 85%, and the activity and the selectivity can be basically kept unchanged after 5 times of circulation. |
