Embodiment 1
[0045] First prepare the raw materials, weigh the C5 fraction, isopentene, toluene and solvent in proportion, and set aside; prepare the first catalyst, weigh aluminum trichloride and methanesulfonic acid in proportion, and put the aluminum trichloride into the flask , add water to dissolve, then add methanesulfonic acid, stir magnetically, heat and distill until the liquid in the bottle becomes viscous, evaporate to dryness, and dry in a vacuum oven at 95°C for 2 hours to obtain the first catalyst; to prepare the second catalyst, press Proportionally weigh urea, ammonium molybdate tetrahydrate, cobalt nitrate hexahydrate, titanium sulfate, aluminum sulfate and ammonia water, dissolve titanium sulfate and aluminum sulfate in deionized water, slowly add ammonia water dropwise, and vigorously stir to adjust the pH to 8 , precipitation and aging for 2 hours, centrifugal filtration, repeated washing with deionized water until the filtrate has no sulfate radicals, drying at 110°C, a...
