Preparation of Benzenamine,N,N-dimethyl-4-(2-phenyldiazenyl)-: it can be prepared by aniline and strong hydrochloric acid. Add aniline into strong hydrochloric acid with crushed ice, and diazotize the sodium nitrite with the hydrochloric acid solution of aniline at the temperature of 0-5 °C. After the reaction, add dimethylaniline and sodium acetate by stirring for 3 hours. By means of filtering, drying and heavy crystallization, you can get the product.

Uses of Benzenamine,N,N-dimethyl-4-(2-phenyldiazenyl)-: it can be used as pH indicator to determine the free hydrochloric acid of gastric juice. In addition, it can be used to get N,N-dimethyl-benzene-1,4-diamine and aniline. This reaction will need reagents Zn and formic acid and solvent methanol. The reaction time is 8 minutes at reaction temperature of 20 °C. ambient temperature. What's more, the yield is about 95%.
