uses | intermediates in medicine and dyes. Used in organic synthesis, pharmaceutical intermediates, etc. |
production method | is prepared by the following reaction of p-bromotoluene: under the condition of light, bromine is added dropwise from the liquid surface to p-bromotoluene at 105 ℃, and the temperature in the early stage of dropwise addition is 105-110 ℃. The temperature in the later period is 135 ℃. After adding, the temperature slowly rises to 150 ℃, then calcium carbonate powder and water are added and stirred evenly, heated and refluxed for 15min for hydrolysis. Then steam distillation is carried out to cool the distillate and filter out p-bromobenzaldehyde crystals. |
