How to convert ethanal to 2-hydroxy-3 butenoic acid? • I was just reminded that butyric acid has a really foul, rancid odour, and so if you are careless in the fumehood, you won't be popular with your lab mates. answered Nov 9, 2018 by Asin (29.3k points) selected Nov 10, 2018 by faiz . The balanced equation for the reaction of butanoic acid (C4H8O2) with ethanol (C2H6O) to produce ethyl butyrate (C6H12O2) is: C4H8O2 + C2H6O = = > C6H12O2 + H2O So for each mole of C4H8O2 used, 1 mole of C6H12O2 will be produced. But ester is not a salt. To subscribe to this RSS feed, copy and paste this URL into your RSS reader.
