The methyl methacrylate (MMA) was synthesized by precision microwave organic synthesis system and its single-mode focusing microwave radiation technology, synchronized Pneumatic gas cooling technology. In the experiment, 2-methyl acrylate and methyl alcohol were used as materials, sulphuric acid as a catalyst for esterification, and hydroquinone as a polymerization inhibitor. Under Discover precision microwave organic synthesis system standard mode, the mol ratio of reaction, the reaction power, the reaction time, and other factors were investigated. The experimental results show that the optimal conditions of microwave heating are as follows: The reaction temperature 70 ℃, the ratio of 2-methyl acrylate and methyl alcohol 1∶2, the power 100 W, the reaction time 30 min, the yield 88%.
