4-二甲氨基苯并苯基酮 - Production method
The mixture of benzoylaniline, N,N-dimethylaniline and phosphorus oxychloride is slowly heated until the reaction starts (sudden heat release), that is, it is changed to cooling, and the temperature is controlled not to exceed 125°C. After the reaction is smooth, heat with boiling water bath for 3h. Cool the reactant to 50°C, slowly pour it into dilute hydrochloric acid, and place it for 3 hours to complete the hydrolysis, and then add water to the reactant to precipitate p-dimethylaminobenzophenone.
