Abstract
Crotonaldehyde is produced by contacting 3,4-epoxybutene, i.e. butadiene monoxide, with a halide-containing catalyst such as a hydrogen halide or metal halide. The process is preferably conducted in the vapor phase. Other unsaturated aldehydes can be produced from other unsaturated terminal epoxides.
