PREPRATION OF ESTERS

The Fischer esterification experiment surprised the researcher greatly and filled him/her with joy in a way. The researcher was surprised to find that many different alcohols mixed with different acids can create various aromas that smell familiar and/or beautiful.

Before the whole experiment, the researcher was skeptical about the outcomes of the mixtures. The researcher refused to believe that just mixtures of different alcohol and acids to create a pleasant smell, especially one that people may use everyday (in perfumes). However, in the end, the researcher realized that different smells, some with foul odors, can still create a beautiful final smell when mixed with an acid of a different smell. This shows that in every bad there is something good. The whole experiment leaves questions on the researchers mind to find out: Are perfumes and fragrances really made this way?

During the making of the experiment, a mistake of keeping the glass jar filled with water in a hot plate with a high temperature was done. This resulted to the over heating and breaking of the glass jar. Because of this incident, the researcher spent a longer time cleaning up the mess and finding ways to substitute the glass jar than exploring and experimententing on different mixtures. The researcher also believes that a preparation of hot bath should be done beforehand to save time. The hot water bath was used for the catalysts to speed up the reaction and ensure the products (in this case, the odor) were made.

The researcher’s advice in the laboratory is to always pay attention when heating something. In addition to that, future researchers should be cautious of the amount of phenol red drops during the pH tests. A little drop can go a long way.

Other safety tips the researcher can also add are:

  • Always gear up – wear safety glasses, a lab coat, and vinyl gloves.
  • Keep all reactants away from flames.
  • Keep reagent bottles capped/sealed when not in use.
  • Do not smell chemicals by placing your nose at the bottle’s opening; waft the smell toward your nose with your hand.

Additionally, the researcher believes that laboratory experiments develop teamwork abilities. It promotes student’s ability to collaborate effectively with each other in carrying out complex tasks, to share the work of the task, and contribute and respond to ideas. Additionally, the researcher believes that more experiment like these should be done. Experiments that makes science “come alive,” and make students become interested in learning more about science and see it as relevant to everyday life. It helps students understand the nature of science. It helps students understand the values and assumptions that science has to offer.
