WebAldehydes are primarily used to manufacture acetic acid but is also used in the manufacture of ethyl acetate, peracetic acid, pyridine derivatives, perfumes, dyes, plastics and synthetic flavouring agents. Formaldehyde has an extremely wide range of uses related to both its solvents and germicidal properties. It is used in plastics production. WebIn basic solution, fructose undergoes tautomeric isomerization to form a small amount of aldehyde. If we use R to represent the last four carbons of fructose, we have. R-C (=O)CH₂OH ⇌ R-C (OH)=CHOH ⇌ R-CH (OH)CH (=O) or. fructose ⇌ an enediol ⇌ an aldehyde. The Tollens reagent oxidizes the aldehyde as fast as it is formed, so the ...
