Use

Acetal (full name: Acetaldehyde diethyl acetal/1,1-Diethoxyethane) 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.
