| overview | o-aminobenzaldehyde is an important intermediate and is widely used in fine chemical and pharmaceutical fields. In medicine, it can further synthesize 2-amino -3,5 dibromobenzaldehyde, and it is a very important intermediate for the synthesis of ambroxol (ambroxol). |
| use | o-aminobenzaldehyde is a commonly used organic synthesis intermediate, dye raw material and pharmaceutical raw material, and is an important raw material for the synthesis of quinoline anti-inflammatory and antiviral drugs. o-aminobenzaldehyde is also an important pharmaceutical intermediate and fine chemical material for the synthesis of ambroxol. Determination of codeine. Biochemical research. Organic synthesis. Dye intermediates. |
| production method | o-nitrobenzaldehyde is obtained by reducing ferrous sulfate and ammonia; ferrous sulfate heptahydrate, concentrated hydrochloric acid, water and o-nitrobenzaldehyde are added to the reactor, stirred and heated, when the temperature of the mixture reaches 90 ℃, concentrated ammonia water is added at one time, and ammonia water is added in three batches. After the feeding is completed, the water vapor mixture is distilled, and the distillate is saturated with sodium chloride and cooled, filtered finished product. |
