The system of conversion, in mild conditions, ethane and propane in carboxylic acids by using catalysts containing vanu00c1dio heteropoliu00c1cidos

摘要

The invenu00c7u00c3o refers to a new system effective for the selective conversion in mild conditions, ethane and propane in carboxylic acids are usually more atom of carbon (reaction (I), this is, and butu00cdricos propionic acids, respectively, which is characterized by the associau00c7 Preparation of a catalyst type heteropoliu00c1cido (HPA) containing vanu00c1dio as H4 [pmo11vo40j x34h2o (HPA-1)H5 [pmo10v2o40] x32h2o (HPA) 2 or H6 [pmo9v3o40] x34h20 (HPA - 3), the k2s208 (oxidizing agent) and carbon monoxide in the solvent CF3COOH (TFA). The income can go down to about 70% and the number of cycles catalu00cdticos (ton) to 1,2x10 ^ 4.
