Description

 

Acetaldehyde is one of the most important aldehydes, occurring widely in nature and being produced on a large scale industrially. It occurs naturally in coffee, bread, and ripe fruit, and is produced by plants as part of their normal metabolism. It is also produced by oxidation of ethanol and is popularly believed to be the cause of hangovers. Traditionally, acetaldehyde was mainly used as a precursor to acetic acid. In terms of condensation reactions, acetaldehyde is an important precursor to pyridine derivatives, pentaerythritol, and crotonaldehyde. Urea and acetaldehyde combine to give a useful resin. Acetic anhydride reacts with acetaldehyde to give ethylidene diacetate, a precursor to vinyl acetate, which is used to produce polyvinyl acetate.
