So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Alvarez-Bermudez, Olaia; Torres-Suay, Ana; Perez-Pla, Francisco F.; Landfester, Katharina; Munoz-Espi, Rafael researched the compound: Picolinamide( cas:1452-77-3 ).Category: tetrahydroisoquinoline.They published the article 《Magnetically enhanced polymersupported ceria nanocatalysts for the hydration of nitriles》 about this compound( cas:1452-77-3 ) in Nanotechnology. Keywords: ceria nanocatalyst hydration crystallization magnetic field. We’ll tell you more about this compound (cas:1452-77-3).
The heterogeneous catalysis of the hydration of nitriles to amides is a process of great industrial relevance in which cerium(IV) oxide (also referred to as ceria) has shown an outstanding catalytic performance. The use of non-supported ceria nanoparticles is related to difficulties in the purification of the product and the recovery and recyclability of the catalyst. Therefore, in this work, ceria nanoparticles are supported on a polymer matrix either by synthesizing polymer particles by so-called Pickering miniemulsions while using ceria nanoparticles as emulsion stabilizers or, as a comparison, by in-situ crystallization on preformed polymer particles. The former strategy presents significant advantages over the latter in terms of time and consumption of resources, and it facilitates an easier scale-up of the process. In both strategies, the incorporation of a magnetoresponsive core within the polymer matrix allows the recovery and the recycling of the catalyst by simple application of a magnetic field and offers an enhancement of the catalytic efficiency.
