While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. Electric Literature of 108-47-4, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In an article，Which mentioned a new discovery about 108-47-4
gamma-Ray irradiation of a binary solution consisting of pyridine and methanol caused almost no reaction of pyridine.However, the addition of a catalytic amount of nickel nitrate to this binary solution induced the alpha-methylation of pyridine in good yield upon gamma-ray irradiation at room temperature either in air or in vacuo.This alpha-methylation gave alpha-picoline as a major product.The yield of alpha-picoline increased with increase in the irradiation time at the initial stage of the reaction, reached a maximum (27.8percent) at an irradiation duration of between 8 and 10h, and then decreased progressively at greater irradiation times.In addition, the yield of alpha-picoline at a given irradiation time showed a tendency to increase with increasing amount of the nickel nitrate catalyst or with increasing fraction of methanol in the starting solution. gamma-Ray irradiation in the presence of nickel nitrate was also found to induce the catalytic alpha-methylation of gamma-picoline with methanol at room temperature either in air or in vacuo, giving 2,4-lutidine as a major product in a maximum yield of 8.3percent.Further, the demethylation reaction of alpha-picoline to pyridine and that of 2,4-lutidine to gamma-picoline were also promoted greatly upon gamma-ray irradiation at room temperature in air in the presence of both methanol and nickel nitrate.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. In my other articles, you can also check out more blogs about 108-47-4
