摘要： PURPOSE: A heavy alkylate is found as a useful raw material of both of the colorless and odorless and non-toxic light and heavy isoparaffin solvents besides as a known additive for high-octane gasoline. CONSTITUTION: A heavy alkylate is produced by introducing C3 and C4 olefine and isobutane into a reactor and adding acid as a catalyst. The olefine and isobutane are mixed together in a volume ratio of 0.5-5:1. The reaction is carried out at 0-30 deg.C. The alkylate contains 10-70 wt.% of isoparaffin component having at least C9, based on total weight of final product. After the reaction on the present of the acid catalyst, the obtained product is separated into acid phase and hydrocarbon phase. The acid phase is returned to the reactor while the hydrocarbon phase flowing into an evaporator. The hydrocarbon phase moves into a separation bed to recover isobutane after removing excess acid fractions.
