Coupling of benzyl cyanide 7.1 with 2-chloropyridine 7.2 gave racemic nitrile 7.3, which was hydrated to the corresponding amide 7.4 by using concentrated sulfuric acid. Reduction of the pyridine was then achieved under hydrogenation conditions with PtO2 as a catalyst, giving rise to a 4:1 mixtur...
The latter is an unwanted byproduct formed in the conventional process, in which caprolactam is produced from cyclohexanone oxime by Beckmann rearrangement, using a sulfuric acid catalyst...Parkinson, Gerald
How is nitric acid prepared industrially? Why is olive oil acidic? why Sudan IV dye is used for detecting the lipids ??? why is H_3PO_4 a better choice than HCl to use as our acid catalyst? Why is it important to add the nitric acid-sulfuric acid mixture slowly over a 15 minute ...
The reaction requires an acid catalyst (sulfuric acid, H2SO4 or hydrofluoric acid, HF) at low temperatures (1-40 degrees Celsius) and low pressures (1-10 atmospheres). The acid composition is usually kept at about 50% making the mixture very corrosive. file:///D|/pafko.com/www/history/...

Introduction N-Methyl-p-aminophenol sulfate is the (2:1) salt of N-methyl-p-aminophenol and sulfuric acid. Due to the instability of N-methyl-p-aminophenol in air and light, it is commonly sold as the sulfate salt, known as metol. N-Methyl-p-aminophenol sulfate is used as a photograp...
