This invention provides an apparatus and method for producing isobutyl methacrylate using a novel membrane reactor. The apparatus integrates a tubular fixed-bed reactor with a pervaporation membrane system. A compartmentalized structure maintains the pressure difference across the membrane, and a dual-tube module optimizes the channel spacing to suppress polymerization side reactions. During the reaction, the pervaporation membrane selectively removes the byproduct water, breaking the equilibrium limitation of the esterification reaction and significantly improving the feed conversion rate. Simultaneously, it disrupts the water-isobutanol azeotropic system, reducing subsequent separation energy consumption and achieving integrated reaction and separation processes. This invention solves the problems of equilibrium limitation on conversion rate, high separation energy consumption, and easy polymerization in traditional processes. It features high conversion rate, low energy consumption, and stable operation, making it suitable for the continuous and green production of isobutyl methacrylate.
