A Little Taste of Chemistry A whiff of what it’s All about Group H Dyshuwnna Nobles, Austin Saunders, Jamil Rogers A Little Taste of Chemistry A whiff of what it’s All about

Did You Catch That Whiff? Perfumes Deodorants Fragrance and Flavor Chemistry plays a vital role in our everyday lives!!! Candy Beverages Food

What’s that smell Ester functional groups are widely studied in the field of organic chemistry Low molecular weight often have a pleasant smell fruit floral candy

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

Possible synthesis

Combinations we MADE!!!!!! 3 methyl-1 butonal 1 butonal 1 propanol 2 Methyl 1 propanol 3 methyl-1 butonal 1 butonal 1 propanol Formic Acid Propionic Acid Phenylacetic Acid Acetic Acid

Instruments These are the instruments that we used to analyze our data Nuclear Magnetic Resonance Infrared Spectrometer Gas Chromatography

Procedures We used Fischer Esterification We measured out our carboxylic acids by their mass and our alcohol by their volume We used 2 moles of alcohol for every 1 moles of carboxylic acid 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

conclusion 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.
