Occurrence

Reported found in cocoa and Bulgarian tobacco

Preparation

By the cold reaction of the corresponding aldehyde with methanol or with orthoformic ester in the presence of acid.

Flammability and Explosibility

Non flammable

Safety Profile

Moderately toxic by ingestion. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES
