Process Description
1,3-Butadiene is an organic compound with the chemical formula C4H6. It is a colorless gas with a faint aromatic odor, insoluble in water but soluble in most organic solvents such as acetone, benzene, acetic acid, and esters. This product is produced via a one-step process and serves as a raw material for the production of synthetic rubber, synthetic resins, nylon, and others.

Technology comment
The one-step ethanol method for preparing 1,3-butadiene uses ethanol as a raw material, which reacts in a reactor under the action of a catalyst at a certain temperature to produce butadiene in a single step. The chemical reaction is as follows: 2 C2H6O -> C4H6 + 2H2O + H2. Based on the chemical reaction, the molar yield of 1,3-butadiene from 1 kg of ethanol is 0.587 kg. In practice, the yield of 1,3-butadiene is lower than the stoichiometric yield due to the formation of by-products such as diethyl ether, ethylene, n-butanol, butenes, and heavy products (C6+).
