Abstract:Investigation has been made on the process for synthesis of salicylaldehyde using phenol,anhydrous magnesium chloride,triethylamine and paraformaldehyde as starting materials.Improvements were made as follows.According to the characteristics of the reaction,the process was divided into two steps.Firstly,magnesium phenoxide was prepared from phenol and magnesium dichloride.Then paraformaldehyde was added.The results showed that the optimal conditions were as follows:The molar ratio of phenol,paraformaldehyde...
Keywords:ultrasonic  phenol  formylation  salicylaldehyde
