摘　　要：Based on a compulsive mixing-reacting-sepa-rating-recycling small experimental setup,the continuous reaction performances of benzene alkylation with long chain olefins catalyzed by[BMIM]Cl-AlCl 3 ionic liquid were investigated.Three different situations including normal continuous operation mode(reagent materials),sidetrack feeding from different axial positions along the static mixing reactor(reagent materials)and normal con-tinuous alkylation using industrial paraffin and olefins materials were examined.Even under the relatively hype-critical reaction conditions,the single pass conversion of pure 1-dodecene could reach to nearly 100.0%,and the selectivity of 2-phenyl isomer was higher than 37.7%.Although the positions along the reactor for sidetrack feeding were different,the 100.0%single pass conversion of 1-dodecene was also attained before the outlet of the reactor.The refined industrial olefins as raw material could meet with the requirements of continuous alkyla-tion.The influences of impurities such as di-olefins and non-benzene aromatics on the catalytic activity and stability should be studied further.
