3-Hydroxybenzaldehyde is one of the three isomers of hydroxybenzaldehyde.

Chemical nature

 
Colorless or light yellow crystalline solid. 
Melting point 103-104°C, boiling point 240°C, 191°C (6.7kPa). 
Slightly soluble in water, soluble in hot water, ethanol, ether and benzene. 
It can be sublimated but cannot be steam distilled.
 
use
 
Used in the synthesis of medicines, dyes and organic compounds. Meta-hydroxybenzaldehyde is used as an intermediate for fine chemicals such as medicines, dyes, fungicides, and photographic emulsifiers. 
As an intermediate, m-hydroxybenzaldehyde is mainly used in the manufacture of medicines, fragrances and dyes. It can also be used as fungicides, photographic emulsifiers, nickel plating brighteners, etc. The drugs synthesized from m-hydroxybenzaldehyde mainly include dehydroadrenal system 
, Adrenaline, Quinine, Otocaine, etc. 
The color developer of Schiff's reagent. 
Pharmaceutical, plastic, dye intermediates. 
Fungicide. 
Photographic emulsifier.
 
production method
 
Using m-nitrobenzaldehyde as a raw material, there are two methods for preparing m-hydroxybenzaldehyde. 
1. It is obtained by addition, reduction, diazo Chemicalbooking and hydrolysis of m-nitroformaldehyde. 
Dissolve sodium bisulfite in water, add m-nitrobenzaldehyde, stir and dissolve at 50°C to obtain an adduct. 
The adduct is present in calcium carbonate, heated to reflux with ferrous sulfate for 3h, and reduced to an amino compound. 
Cool the reducing liquid to below 15°C, add dropwise sodium nitrite solution for diazotization, and then hydrolyze at 100-110°C to obtain m-hydroxybenzaldehyde. 
After decolorization of activated carbon and recrystallization with water, the finished product is obtained. 
2. It is obtained by reducing m-nitrobenzaldehyde with stannous chloride, then diazotizing and hydrolyzing. 
Prepare a solution of powdered stannous chloride dihydrate, cool to 5°C, and add m-nitrobenzaldehyde. 
After slowly raising the temperature to 25-30°C, the temperature rises rapidly. When it reaches 100°C, cool and stir vigorously to obtain an orange paste. 
Add concentrated to form a suspension, slowly add sodium nitrite aqueous solution while stirring, and control the temperature at 4-5°C. 
After the addition, stir for 1h. 
Cool to crystallize, filter out the diazonium salt, add it to boiling water for hydrolysis, and decolorize with activated carbon. 
Filter while hot, cool and crystallize to obtain the finished product.
