An excess of the alcohol means that there … WebOct 5, 2024 · The direct transformation of alcohols into esters is receiving increasing attention and can avoid the use of hazardous acids and their derivatives and eliminate the generation of undesirable products (for example, aldehydes and acids), leading to significantly improved overall reaction efficiency (4–11).Direct transformation of alcohols …
WebAldehydes are commonly prepared by the oxidation of alcohols whose –OH functional group is located on the carbon atom at the end of the chain of carbon atoms in the alcohol: Alcohols that have their –OH groups in the middle of the chain are necessary to synthesize a ketone, which requires the carbonyl group to be bonded to two other carbon atoms:
