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. The industry produces ethyl ethanoate in a huge capacity. Laboratory methods are
conducted at a much smaller scale. However, even industrials don’t give out 100% yield outcome for
ethyl ethanoate. This can be due to a wide number of factors. Computer errors can occur. This is one
of the most common errors during industrial production. This type of error will affect the process of
the production, which therefore will lead to impurities during the process and an unreliable yield
outcome.
Two factors that affect the purity of ethyl ethanoate are:
Reflux
Distillation
The mechanisms both increase the purity of the sample by taking the impurities out the mass.
