| titleOfInvention | High-efficiency synthesis method of acetanilide and acetanilide |
| abstract | An efficient synthesis method of acetanilide and acetanilide, belonging to the field of chemical industry. The high-efficiency synthesis method comprises the following steps: atomizing aniline to obtain a first raw material, mixing concentrated hydrochloric acid and water, atomizing to obtain a second raw material, and introducing the first raw material and the second raw material into a mixing chamber to mix to obtain a mixture. Under the stirring action of the sodium acetate solution, the mixture is blown into the sodium acetate solution by inert gas preheated to 180-200 ℃ while acetic anhydride is introduced into the sodium acetate solution. The reaction efficiency is high, the continuity is good, the reaction can be started and stopped at any time, and the flexibility is good. The acetanilide is prepared by the efficient synthesis method, and has high purity, low cost and convenient preparation. |
