In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Deactivation during the hydrogenation of 2-methylglutaronitrile to β-picoline, published in 1994, which mentions a compound: 4553-62-2, mainly applied to hydrogenation methylglutaronitrile; glutaronitrile methyl hydrogenation; picoline preparation, Application In Synthesis of 2-Methylglutaronitrile.
A strong correlation between conversion and product selectivity was found for the production of β-picoline from 2-methylglutaronitrile in a single-stage process. The conversion had to be maintained at a very high level in order to keep the intermediates concentration low, thus preventing the formation of coke precursors by condensation reactions. The intermediates concentration on the metal surface was strongly influenced by the reaction temperature and the partial pressures. Above 598 K, the selectivity for condensation products decreased sharply, but also the overall conversion decreased. This neg. effect could be compensated by an increased hydrogen partial pressure.
This literature about this compound(4553-62-2)Application In Synthesis of 2-Methylglutaronitrilehas given us a lot of inspiration, and I hope that the research on this compound(2-Methylglutaronitrile) can be further advanced. Maybe we can get more compounds in a similar way.
