설명

일반 설명

Propionic acid is a linear monocarboxylic acid. It affords esters on reaction with alcohols or alkenes. It can be synthesized by reacting ethane, carbon monoxide and water. It participates as a precursor in the preparation of smallest azolium homoenolate intermediate.

애플리케이션

Propionic acid may be used in the synthesis of cellulose propionate (cellulose ester).
