An aldehyde is a compound in which a hydrocarbon group (or hydrogen atom) is connected to an aldehyde group. Aldehydes can be divided into fatty aldehydes and aromatic aldehydes, monoaldehyde and dialdehydes. Aldehydes are mainly strongly reducing, and their oxidizing properties are average. Aldehyde groups are relatively lively and can undergo addition and condensation reactions.

More Information

Aldehyde is an organic compound with the general formula RCHO, where R stands for hydrocarbon group. Aldehydes are composed of a hydrocarbon group (or hydrogen atom) connected to an aldehyde group (-CHO). It contains carbonyl groups in their molecules, with hydrogen atoms directly connected to the carbonyl group. Based on the different hydrocarbon groups, aldehydes can be classified as aromatic aldehydes, fatty aldehydes and so on.

The relevant chemical reactions of aldehydes contain nucleophilic addition reaction and oxidation reaction. They can be obtained by alcohol oxidation, olefin oxidation, alkyne hydration, etc. Besides, Aldehyde compounds have many vital chemical properties and applications, such as participating in various chemical reactions and being important intermediates in the process of organic synthesis.

The application of oxidation of aldehydes

1. Synthesize chemical industrial products, such as methanoic acid

2. Synthesize ketone compounds

3. Used in biology study
