| use |
Salicylaldehyde is a kind of perfume and a widely used organic synthesis intermediate. In drug synthesis, it is often used to synthesize salinazid, benzbromarone and acetoamine benzophenone.
Verification of hydrazine. Spectrophotometric Determination of scandium. Extraction separation of nickel and cobalt. To test the odor and organic synthesis of nickel, copper, fusels and ketones. Spices. |
| production method |
It is obtained by the reaction of phenol and chloroform in sodium hydroxide solution. The improved preparation method uses o-cresol as raw material, phosgenation, chlorination and hydrolysis to obtain salicylaldehyde.
It is obtained by the reaction of phenol and chloroform in the presence of caustic solution. |
