Factors affecting the yield and purity of ethyl ethanoate
Industrial methods are more reliable than laboratory methods because they have more precise
technologies which are used, and machinery allows more control of the intakes of the
measurements. However, even industrials don’t give out 100% yield outcome for ethyl ethanoate.
Computer errors can occur, which will affect the process of the production, which will lead to
impurities during the process
Reflux: decreases
Distillation: decreases
These both increase the purity but my taking the impurities out the mass decreases.
Analyse whether boiling point measurement and infrared spectroscopy are effective ways to
assess whether ethyl ethanoate is pure and comment on the reliability of the test methods used

it inside the infrared spectrum.
The spectrum will then be
compared to the spectrum of a
pure ester, and any
extraneous peaks in the
spectrum will show that the
solution contains impurities.
However, if the peaks were
like a known impurity, then
they would use the intensities
