It is a Colorless transparent liquid that dissolves in water, alcohol, and ether. The name succinaldehyde is often incorrectly used in commerce as a synonym for succinic anhydride.
Succinaldehyde (SA) was added directly into UF resins before application for plywood production; these urea-formaldehyde-succinaldehyde (UFSA) resins, as they were formed during curing, improved markedly the water resistance of the hardened UF bondline as well as decreased its formaldehyde emission.
Preparation method of succinaldehyde: Using furan as the raw material, 2,5-Dihydro-2,5-dimethoxyfuran is prepared by electrolysis, followed by hydrogenation and hydrolysis to obtain succinaldehyde. Alternatively, Cyclododeca-1,5,9-triene can be used as the raw material. In ethyl acetate, at -20 to 10°C, it is oxidized with 3% ozone to produce triene ozonide. It is then subjected to catalytic hydrogenation with 5% lead-activated carbon at room temperature to prepare succinaldehyde.
ChEBI: Succinic aldehyde is an aldehyde.
