Use
Acetaldehyde is also known as ethanal, acetaldehyde is miscible with H2O, alcohol, or ether in all proportions. Because of its versatile chemical reactivity, acetaldehyde is widely used as a commencing material in organic syntheses, including the production of resins, dyestuffs, and explosives. The compound also is used as a reducing agent, preservative, and as a medium for silvering mirrors. In resin manufacture, paraldehyde (CH3CHO)3 sometimes is preferred because of its higher boiling and flash points.
