Succinaldehyde Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
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.
Verwenden
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.
synthetische
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.
Definition
ChEBI: Succinic aldehyde is an aldehyde.
