Ester functional groups are widely studied in the field of organic chemistry

Low molecular weight often have a pleasant smell fruitfloralcandy

We are exploring different syntheses and extractions to create an ester.

Our main goal was to improve the protocol on creating the ester.

The protocol was meant to improve the yield of many esters through combinatorial chemistry.

This experiment will be used in the undergraduate organic chemistry lab.

Fischer Esterification is the process in which an alcohol and a carboxylic acid are combined and form an ester.

Combinations we MADE!!!!!!

1 propanol

2 Methyl 1 propanol 3 methyl-1

butonal1 butonal

Formic Acid

Propionic Acid

Phenylacetic Acid

Acetic Acid

Nuclear Magnetic Resonance Gas

Chromatography

Infrared Spectrometer

These are the instruments that we used to analyze our data

1. We used Fischer Esterification1. We measured out our carboxylic acids by their mass and our

alcohol by their volume2. We used 2 moles of alcohol for every 1 moles of carboxylic

acid3. Avagadro’s number is the number used in a mole. It is the

amount of how many molecules are in a mole. The number is 6.022142*10(23)

Heating Process….

We heated our mixture for an hour

Washing of our product……

We washed our mixture using biocarbonate to rid the substance of the sulfuric acid and carboxylic acid

Austin’s Jamil’s

We were able to create an ester using different synthesis and extractions.

Further Research

If water washes don't get rid of the alcohol, we might have to include distillation.
