Having gained chemical understanding at molecular level, 108-47-4, Name is 2,4-Dimethylpyridine, belongs to chiral-nitrogen-ligands compound, is a common compound. 108-47-4 chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. In an article, authors is Kashiwagi, Hiroshi, once mentioned the new application about 108-47-4.
The heterogeneous vapor-phase alkylation of pyridine with methanol over Na+, K+, Rb+, or Cs+ exchanged X- or Y-type zeolite in an atmophere of nitrogen resulted in the formation of 2- and 4-ethylpyridines and 2- and 4-vinylpyridines together with picolines and lutidines.Next, the alkylation of alpha-, beta-, and gamma-picolines with methanol was studied over alkali cation exchanged zeolites and was found to produce mainly the side-chain methylated derivatives: ethylpyridines and vinylpyridines.However, considerable amounts of ring-alkylated derivatives (lutidines) were formed simultaneously.In general, the catalytic activity became observable under reaction conditions involving both a high temperature and a small flow rate of carrier gas (N2).The yields of ethylpyridines were highest when the CsY catalyst was used at 450 deg C, whereas the yields of vinylpyridines were highest when the CsX catalyst was used at 425 deg C.This catalytic side-chain alkylation over alkali cation exchanged zeolites was successfully applied to a variety of picolines, lutidines, and ethylpyridines with either methanol or ethanol.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, they are the focus of active research. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 108-47-4
