Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1452-77-3, is researched, Molecular C6H6N2O, about Silica supported potassium oxide catalyst for dehydration of 2-picolinamide to form 2-cyanopyridine, the main research direction is picolinamide cyanopyridine silica potassium oxide catalyst dehydration.Quality Control of Picolinamide.
The dehydration of 2-picolinamide to produce 2-cyanopyridine was investigated thoroughly using silica supported potassium oxide as a heterogeneous catalyst. Both large sp. surface area and pore size of SiO2 (B) contributed to the favorable catalytic performance for the synthesis of 2-CP. In addition, the yield of 2-CP showed the linear relationship with the amounts of medium basicity of the catalysts, demonstrating that medium basic sites were the active sites of silica supported potassium oxide catalysts. The catalysts were further characterized by XRD and FT-IR to clarify the active species. The results indicated the Si-O-K group produced by the reaction of K2CO3 with Si-OH was the active species, which was further evidenced by the adjustment of the amount of Si-OH by silylation and hydroxylation procedure.
After consulting a lot of data, we found that this compound(1452-77-3)Quality Control of Picolinamide can be used in many types of reactions. And in most cases, this compound has more advantages.
