| General description: | Acetaldehyde is a highly inflammable liquid, which can be commercially produced from liquid-phase oxidation of ethylene. It can also be obtained as a co-product from the oxidation of saturated hydrocarbons like propane or butane. It can find applications as a chemical intermediate in the production of acetic acid. |
