The invention discloses a preparation method of gamma-methylacryloyloxy propyl alkoxy silane, and relates to the technical field of preparation of gamma-methylacryloyloxy propyl alkoxy silane. According to the invention, potassium methacrylate or sodium methacrylate reacts with chloralkane silane, and the raw materials are easy to obtain; no solvent participates in the reaction process, solvent recovery is not needed, personal injury caused by personnel contact is avoided, the process route is shortened, and operation is simpler; a water washing process is used, so that the product recovery is more thorough, the yield is relatively high, the input amount of each batch is 2,400 kg, the output is 2750-2780 kg, and about 80 kg of products are extracted from each batch on average compared with the original process; the efficient organic amine catalyst is used, the reaction time is short, and the crude product content is high. 本发明公开了一种γ-甲基丙烯酰氧基丙基烷氧基硅烷的制备方法，涉及γ-甲基丙烯酰氧基丙基烷氧基硅烷制备技术领域。本发明利用甲基丙烯酸钾或甲基丙烯酸钠与氯代烷烃硅烷反应，原料易得；
