Acetaldehyde diethyl acetal, also known as acetal or diethyl acetal, is a chemical compound with the formula CH3CH(OCH2CH3)2. It is a colorless liquid with a pleasant, fruity odor. Acetaldehyde diethyl acetal is a derivative of acetaldehyde and ethanol, formed through an acetalization reaction. This reaction typically involves the addition of ethanol to acetaldehyde in the presence of an acid catalyst.

The compound is used as a flavoring agent in food products, contributing to fruity and alcoholic notes. It is also employed as a solvent in various industrial applications, including the production of lacquers, resins, and perfumes. In organic synthesis, acetal acts as a protecting group for aldehydes. This means it can be temporarily converted into an acetal to prevent the aldehyde group from reacting during other chemical transformations. Once the desired reactions are complete, the protecting group can be removed to regenerate the original aldehyde.

Acetaldehyde diethyl acetal is flammable and should be handled with care. It is soluble in organic solvents like ethanol and ether but has limited solubility in water. Its stability is good under neutral or alkaline conditions, but it can hydrolyze back to acetaldehyde and ethanol in the presence of acids. The synthesis and application of acetal are well-established within the chemical industry.
