This reaction, termed Fischer esterification in honor of its discoverer, can be used to product obtained (i e the yield) will be measured and the percent yield

The carboxylic acid is the limiting reagent Using acetic acid? ⇒ The alcohol is the limiting reagent Weigh compounds directly into the reaction flask Be careful
exp
For esters in which the alcohol and carboxylic acid are sterically unhindered, a 1:1 mixture of alcohol and carboxylic acid will yield an equilibrium mixture that is about 70 ester This means that if ester were isolated from this mixture, at best a 70 yield would be obtained
