The invention discloses a method for feeding acetone cyanohydrin during preparation of methyl methacrylate. The method comprises a step of jetting acetone cyanohydrin into an amide circulation loop, wherein the amide circulation loop is composed of an amide cooler, a gas separator and an amide circulation pump which is located between the outlet of the gas separator and the inlet of the amide cooler. According to the invention, through jetting of acetone cyanohydrin into the amide circulation loop at a plurality of positions, smaller acetone cyanohydrin drops are formed, so material mixing is more sufficient and faster, the decomposition degree of acetone cyanohydrin is reduced, the conversion rate of amide is increased, and unnecessary consumption of acetone cyanohydrin is lowered; thus, the conversion rate of an acylation reaction is increased.
