| 摘 要： | A new type of reactor,featured with impinging stream-rotating packed bed(IS-RPB)and coil pipes,was designed and used to prepare p-hydroxybenzaldehyde(PHB)by hydrolysis from diazonium salts.The influence of operating parameters,such as reaction temperature,reaction time and high gravity factor,on the yield of PHB was investigated.Compared with the traditional kettle-type reactor,the yield of PHB with the new reactor is increased significantly and the reaction time is much shorter.Under the optimum conditions,the yield of PHB is increased from 51%to 84.1%.The reactor offers an opportunity for replacing the traditional batch mode operation with a continuous process.

Under the optimum conditions, the yield of PHB is increased from 51% to 84.1%. The reactor offers an opportunity for replacing the traditional batch mode operation with a continuous process. |
