It is obtained by reacting p-chlorobenzaldehyde with acetic anhydride. The p-chlorobenzaldehyde, acetic anhydride and sodium acetate were reacted together at 180 ° C for 13 h. After the reaction, it was slightly cold, poured into water, filtered, and the filter cake was washed with water and repeatedly dissolved with ammonia water until only a small amount of brownish yellow viscous remained. The obtained ammonium salt solution was filtered, and p-chlorocinnamic acid was re-precipitated with 3N dilute sulfuric acid, and dried by filtration to obtain a product. The yield is about 80%.
