production method | p-nitrocinnamonitrile, concentrated hydrochloric acid and water were heated under reflux for 8h and allowed to stand overnight. The precipitate was filtered off, dissolved in hot 30% sodium hydroxide solution, and the insoluble matter was filtered off. The filtrate was acidified with 50% sulfuric acid to precipitate precipitating pyridine, and the crude product was filtered and recrystallized with ethanol to obtain p-nitrocinnamic acid. |
