Methyl p-chlorocinnamate

Methyl p-chlorocinnamate is an organic chemical, often used in industry, pharmaceutical industry, etc., obtained by reacting chlorobenzaldehyde with acetic anhydride. The chlorobenzene formaldehyde, acetic anhydride and sodium acetate with reaction 13h under 180 ℃. After the reaction, it is slightly cold. Pour into the water, filter and wash the filter cake with water. Dissolve the cake repeatedly with ammonia until only a small amount of brownish-yellow sticky remains remain. The ammonium salt solution was filtered, then the chlorocinnamic acid was precipitated out with 3N dilute sulfuric acid, and the product was filtered and dried.
