Technology comment
The two-step ethanol method for preparing 1,3-butadiene was developed based on the one-step method. First, in one reactor, ethanol is dehydrogenated to form acetaldehyde under the catalysis of a basic catalyst (such as a copper-based catalyst); then, in another reactor, acetaldehyde reacts with ethanol to produce butadiene. The chemical reactions are as follows:
C2H6O -> C2H4O + H2
C2H6O + C2H4O -> C4H6 + 2H2O
