Product Name:Isonicotinic acid
CAS Number:55-22-1
Molecular formula:C6H5NO2
Molecular Weight:123.11

Isonicotinic acid is synthesized by continuous oxidation with 4-methylpyridine as raw material and vanadium pentoxide as catalyst. The purity of the industrial product isonicotinic acid is more than 95%, and the yield of the above method is 70-75%. The consumption of 4-methylpyridine per ton of product is 1070kg.

Reaction Conditions:

with sulfuric acid;ozone;acetic acid;manganese(II) acetate at 16; for 1 h;

Steps:

9 Example 9:

Example 9: 4-Pyridinecarboxylic Acid In a 100 ml jacketed vessel, 200 ml of acetic acid, 0.05 g of manganese(II) acetate, 1.91 g of sulfuric acid and 14.1 g of 4-methylpyridine were initially charged. The mixture was cooled to 16° C. and 4.0 g of ozone were introduced within a period of 60 minutes. After completion of ozonolysis, the ozone present in the solvent was blown out using nitrogen. Analysis of the reaction mixture by means of HPLC or GC gave the following results: 4-methylpyridine: >0.1%; 4-pyridinecarboxylic acid: 97%
