The invention relates to an immobilized ionic liquid catalyst and application thereof. The immobilized ionic liquid catalyst has a general structural formula as defined in the specification. In the general structural formula, P is a nanometer macroporous resin matrix; n is an integer in a range of 2 to 12; and M<-> is a negative ion selected from a group consisting of a trifluoromethanesulfonate group, a p-toluenesulfonate group, a benzenesulfonate group, a methanesulfonate group, a tetrafluoroborate group and a hexafluorophosphate group. The immobilized ionic liquid catalyst can be applied to industrial olefine acid addition for preparation of corresponding esters. 本发明涉及种固载化的离子液体催化剂及其用途。所述固载化的离子液体催化剂，具有以下结构通式：其中，为纳米大孔树脂基体；n为2到12的整数；M为阴离子，选自三氟甲磺酸根、对甲苯磺酸根、苯磺酸根、甲烷磺酸根、四氟合硼酸根或六氟合磷酸根。所述固载化离子液体催化剂可用于工业化烯酸加成制备相应的酯。
