O-carboxybenzaldehyde nature, use and production process
Chemical properties
The fronds crystallize. 98-99 ° C (96-98 ° C).
Used as a pharmaceutical intermediate
Organic Synthesis.
production method 
It is obtained by bromination and hydrolysis of phenol. The phenylhydrazine is heated to 140-145 ° C, and a bromine reaction is carried out to control the rate of introduction, so that the reaction off-gas is substantially free of bromine vapor. After passing through Bromine, the residual hydrogen bromide was removed by passing carbon dioxide and decompression at 120 °C. The reaction was added with water and hydrolyzed in a boiling water bath for 0.5 h. After cooling, o-carboxybenzaldehyde was precipitated. The yield was 60%.
