Esterification Lab
Investigation and Preparation of Esterification Lab
Introduction
Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups, one which is bonded to an oxygen, and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters are named in almost a reverse fashion where the R-group bonded to the oxygen is named first with the ending “yl” and the R- group bonded to the C coming second ending with an “oate.” The “yl” group is derived from the alcohol that was used to make …show more content…
In addition, writing balanced chemical equations.
Hypothesis
If methyl-2-propanol is reacted with formic acid then the product should be 2-methylpropyl methanoate.
If 1-octanol is reacted with acetic acid then the product should be 1-octyl ethanoate.
If methanol is reacted with salicylic acid then the product should be methyl salicylate.
If 1-pentanol is reacted with acetic acid then the product should be pentyl ethanoate.

a) ethanoal + benzanoic acid = ethyl benzanoate b) 1-propanol + butanoic acid = propyl butanoate
4. a) 1-octyl propanote = propanoic acid + 1 ocatnol
b) 1-propyl pentanoate = pentanoic acid + 1-propanol
5. Oil of wintergreen is also known as an aspirin because of its involvement in the aspirin family. This is known because the aspirin family is associated to the salicylate part of the oil wintergreen. The name for this oil is methyl salicylate which is why it is associated with the aspirin. It is uses for the cure of headaches because as we know aspirin is a blood thinner anti-coagulant. So it is normal for commercials that advertise oil of wintergreen are for things like headache relief.
Sources of Error
1. A potential source of error that may have occurred in this lab is possible side reactions in the experiment. This could take away from the overall production of the ester or even create side products that we may have noted wrongly when we were wafting the
