摘要

"Catalyst of vanadium based on modified clay.Process for the preparation of a catalyst of vanadium based on modified clay and process for the conversion of 3 - picolina in 3 - cianopiridina in one step. The present invention relates to a process for the preparation of a catalyst converter of amonoxidau00e7u00e3o highly active using a metal oxide complex which contains P,V and supported on Ti PILC,The process involves the heating in a water bath of a source of vanadium with oxalic acid in the presence of water for the formation of oxalate of vanadilo; adding a source fosforosa and fonYou and you PILC and heating the resulting mixture in the presence of air at a temperature in the range of between 110 198 C to 450 198 C for a period in the range of 15 to 35 hours and the use of the catAmonoxidau00e7u00e3o straightener in the preparation of aromatic nitriles - straight from methyl pyridine which comprises passing a stream of a gas mixture comprising reagent.A pyridine methyl substituted, ammonia and oxygen (air) on the fixed base catalyst amonoxidau00e7u00e3o at a temperature of about 350 C 198 198 450 C.
