Direct Oxidation of 3-Picoline to Niacin

The green advantages of the direct oxidation process can be summarized as follows  

Use of air as oxidant instead of stoichiometric quantities of chemical oxidizing agents. 

Gas-phase reaction means that catalyst does not have to be recovered from solution. 

Few unit operations necessary to obtain the pure product. 

Conversion is high, leading to an efficient use of equipment, energy and material.
