Product name:Isonicotinic acid
CAS: 55-22-1
Molecular Formula: C6H5NO2
Molecular Weight: 123.102
Product description:The water of crystallization for white odorless crystalline. Slightly soluble in water.Heated to 260 ℃ in the oxidation of fluidized bed reaction tower, the catalyst vanadium pentoxide activation 12 h, preheat temperature to 255 ~ 260 ℃, then add 4 - methyl pyridine, the preheating gasification mixed with steam, air, into the oxidation tower, the reaction of isonicotinic acid powder collected by the cyclone separation, via condensation reaction exhaust absorbed with dilute hydrochloric acid circulation, with recovery unreacted 4 - methyl pyridine and entrainment isonicotinic acid.It is mainly used for anti-tb drugs isoniazid, also used in the synthesis of amide, hydrazine, esters and other derivatives.
