CATALYTIC METHOD FOR THE PRODUCTION OF NITRILES FROM ALCOHOLS

摘要

The invention relates to a catalytic method for the production of nitriles form alcohols, such as polyols, for example glycerol, a reaction known as ammoxidation. For this purpose, the alcohol is reacted with a nitrogen source, such as, for example, ammonia, in the presence of an oxidising agent, such as oxygen or hydrogen peroxide, and in the presence of a catalyst. Alumina-supported catalysts containing oxides of V, Nb and Sb achieve yields above 48% in ammoxidation of glycerol to acrylonitrile. The invention is particularly suitable for obtaining high-added-value products such as acrylonitrile from glycerol which is produced as a by-product in biofuel production.
