Butanoic Acid – Structure, Properties, Production and Uses

Chemical Properties of the Butanoic Acid - C4H8O2 Butanoic acid reacts with the sodium hydroxide and forms carbon dioxide, the sodium salt of butanoic acid, and water. The chemical equation can be given as follows. 21C₄H₈O₂ + 20NaOH → 20NaC₄H₆O + 4CO₂ + 34H₂O Butanoic acid, on treatment with the water, produces ether and acetic acid.
