It is easy to hydrolyze in methyl acetate, and it can hydrolyze to produce acetic acid by hydrolysis at normal temperature. When heated, it is decomposed into acetaldehyde and formaldehyde, which can be further decomposed into methane, carbon monoxide and hydrogen. Halogens, especially iodine, have a catalytic effect on decomposition. In the presence of nickel, will be heated, methyl acetate decomposition does not occur under 150 ℃, more than 150 ℃ is decomposed into methane, carbon monoxide and water. When heated with air, the catalysts of copper, silver, molybdenum and other metals are decomposed into formaldehyde and acetic acid. Methyl acetate is decomposed into methanol, acetone, diacetyl, ethane, methane, hydrogen, carbon monoxide and carbon dioxide. Chloroacetic acetate was produced by reacting with chlorine under light. In the presence of sodium methoxide and methyl acetate in 57 ~ 80 ℃ by condensation, methyl acetoacetate is generated. Methyl acetate with certain salts, such
