| titleOfInvention | A process for preparing 2-acetyl nicotinic acid |
| abstract | The present invention relates to a method for preparing 2-acetylnicotinic acid, and more particularly, in the preparation of 2-acetylnicotinic acid by reacting nicotinic acid N-oxide with acetic anhydride and deoxygenating, the conventional deoxygenation The reaction caused pollution and increased production cost by using PBr 3 or PCl 3 , while deoxygenation was carried out under Pd / C catalyst and hydrogen atmosphere and treated with alkaline aqueous solution and aqueous acid solution. A method for producing high purity 2-acetylnicotinic acid. |
