Manufacturing

• Acetaldehyde (air oxidation): acetaldehyde + oxygen (Hoechst-Shawinigan process; coproduced with acetic anhydride): acetaldehyde (air oxidation; coproduced with peracetic acid): methanol + carbon monoxide (BASF/Monsanto carbonylation processes): methanol + carbon monoxide (BP acetyls process; coproduced with acetic anhydride): naphtha, heavy (liquid-phase oxidation; coproduced with acetone/methyl ethyl ketone/formic acid/propionic acid): n-butane (Celanese LPO process; coproduced with methanol/ethanol/acetone/methyl ethyl ketone/formic acid/propionic acid/n-butyric acid/methyl formate): acetic anhydride + cotton linters/bleached wood pulp (acetylation/partial hydrolysis; byproduct of cellulose acetate production)

• Liquid- and vapor-phase oxidation of petroleum gases (with catalyst); ... oxidation of acetaldehyde; ... reaction of methanol and carbon monoxide (with catalyst; this is the most cost efficient method and has been in general use for some years); ... fermentative oxidation of ethanol.

• Obtained in the destructive distillation of wood; from acetylene and water, via acetaldehyde by oxidation with air.

• The major routes for synthetic acetic acid include methanol carbonylation, acetaldehyde oxidation, butane/naphtha oxidation, and methyl acetate carbonylation. Comparatively small amounts are generated by butane liquid-phase oxidation, direct ethanol oxidation, and synthesis gas.
