Mainly Used in the Manufacture of Vitamin B, Niacin, Cardiotonic Agents, Etc. It Can Also Be Used as a Solvent, Alcohol Denaturant, Various Intermediates, And Pesticides.

Production Method

Recovered from Coal Coking Byproducts, Also Produced by Synthesis. It Is Produced by the Reaction of Acetaldehyde, Formaldehyde and Ammonia. Sio2-Al2o2-Bi2o3 Is Used as a Catalyst, The Molar Ratio of the Raw Materials Is Acetaldehyde: 37% Formaldehyde: Ammonia = 1.648: 3.096, The Reaction Is Carried out at 432°c, The Pyridine Yield Is 48.4%, And the 3-Methylpyridine Yield Is 27.0%. The Proportion of Product Formation Can Be Adjusted by Changing the Catalyst Composition and Other Reaction Conditions. Selecting the Appropriate Ingredients and Catalyst, Using Hexamethylenetetramine Instead of Ammonia, The Yield of 3-Methylpyridine Can Reach 59.7%.
