Description

Acetal, also known as Diethyl acetal or Acetaldehyde diethyl acetal is a major flavoring component of distilled beverages, especially malt whisky and sherry. Acetaldehyde diethyl acetal is used as a flavoring agent to provide fruit, nut, rum, and whiskey flavors. It can react with diketene to form ethyl 5-ethoxy-3-oxohexanoate in the presence of titanium chloride. It can also be used to synthesize mixed acetal glycosides via transacetalation.

Features

1. Chemical structure: It contains an acetal functional group (two ether groups bonded to the same carbon). This structure makes it a colorless liquid with a relatively low boiling point (102 °C).

2. Volatility: It's highly diffusive and evaporates quickly.

3. Odor: It has a characteristic odor described as alcoholic (with hints of moonshine or whiskey), green-fruity, and with nutty nuances.

4. Flavor: It's a major flavoring component in various distilled beverages, particularly malt whisky and sherry.

5. Safety: It's flammable and can irritate skin and eyes. When handling it, proper safety precautions are crucial, including using explosion-proof equipment and keeping it away from heat sources.

Applications
