The process in which an organic acid and an alcohol react toform an ester and water is known as esterification. Ethyl butanoate(C3H7COOC2H5) an ester is formed when the alcohol ethanol (C2H5OH)and butanoic acid (C3H7COOH) are heated in the presence of sulfuricacid. C2H5OH(l) + C3H7COOH(l) C3H7COOC2H5(l) + H2O(l) Determine themass of ethyl butanoate produced if 4.20 mol of ethanol isused.
