Anhydrides are the chemical reaction of two carboxylic acids, which produces an acid anhydride and a water molecule.
CH3CH2COOH + CH3CH2COOH → CH3CH2COOCOCH2CH3 + H2O
propanoic acid + propanoic acid → hexanoic anhydride (propanoic propanoic anhydride)
Acid anhydrides are significant in Organic Chemistry as acid anhydrides are involved in esterification with alcohol as a reagent without an catalyst to form an ester. N. Goaly https://chemrevise.files.wordpress.com/2018/11/6-1-3-revision-guide-carboxylic-acids-and-esters.pdf view online 05/12/2018
(C2H5CO)2O + CH3 CH2OH → CH3CH2COOH + CH3CH2COCH2CH3
hexanoic anhydride + ethanol → propanoic acid + ethyl propanoate
propanoic propanoic anhydride
Esters are used for industrial purposes as such as flavouring and perfumes.
