Typical reaction times vary from 1–10 hours at temperatures of 60-110 °C.
Direct acylations of alcohols with carboxylic acids is preferred over acylations with anhydrides (poor atom economy) or acid chlorides (moisture sensitive).

What is the percent yield for the Fischer product?

Based on the experiment that was conducted the synthesis of isopentyl acetate from a carboxylic acid and an alcohol could be done by a Fisher Esterification reaction, and the percent yield of the product is about 61.9%._{16 août 2017}

What is the percent yield of an ester?

With a 1:1 mixture of carboxylic acid and alcohol, the esterification reaction reaches equilibrium with about 70% yield of the ester._{26 mar. 2020}

What is the yield of Fischer esterification?

This esterification reaction is reversible.
With a 1 to 1 mixture of the carboxylic acid and the alcohol, it tends to reach equilibrium with about a 70% yield of the ester at best.

It was found that running the Fischer esterification using equal amounts of acetic acid and ethanol gave a 65% yield of the ester at equilibrium. Not bad. But the reaction could be driven even further to the right by using a 10-fold excess of the alcohol. In this case they obtained a 97% yield of the ester.
