O-toluidine by diazotization, displacement derived. The solution of o-toluidine and 40% hydrobromic acid was cooled to 0-5 °C, and sodium nitrite solution was added dropwise to control the dropping rate and avoid the overflow of brown gas. After the addition was complete, stir for 15 min and test the end point with potassium iodide starch (it should be blue immediately). After completion of diazotization, copper powder was added and heated carefully. The temperature was raised to 25-30° C. to stop heating, and the natural temperature increase was controlled to not exceed 50° C., and the reaction escaped nitrogen gas. After incubation at 50°C for 1 hour, the reaction solution was steam-distilled to obtain an oily substance which was washed successively with 30% aqueous caustic soda, concentrated sulfuric acid and water, and dried with anhydrous calcium chloride to obtain purified o-bromotoluene.
