Bacani‚ and Steven Arthur Baluyot Analysis of Hydrocarbons Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract In this experiment we performed parallel chemical test method to identify an unknown. The reflux setup was used to prevent evaporation in mixing the reactants in an inert solvent with its boiling point. Another highlight of this experiment is the liquid-liquid extraction wherein a solution containing

Preparation of an Acetic Acid Ester Abstract: 14.1 g of octyl acetate were synthesized from the esterification process using 20.0 ml of acetic acid and 17.9 g of n-octanol. The theoretical yield was 23.8 g of octyl acetate. The percent yield was 59.2%. The purification of the final ester was confirmed by boiling point (186-199°C) and infrared index (nD=1.419). It was a colorless liquid that had a slight fragrance of orange and indescribable chemicals. The Infrared spectra confirmed ester

250 ppm‚ 200 ppm‚ 100 ppm‚ and 25 ppm of 12C solution was prepared from a caffeine stock solution using ethyl acetate as the solvent. 250 µL of each dilution was added to a respective 0.6 mL vials with 50 µL of 13C and mixed. Next‚ three 15 mL centrifuge tubes were labeled as “Unknown A‚” three were labeled as “Unknown B” and one was labeled “Control.” To each tube‚ 4 mL of ethyl acetate and 1 mL of the respective unknown or control (100 ppm 12C solution) was added to the respective flasks.

The percent yield of the isopentyl acetate was 74.3% and this low percent yield could have occurred due to some amount of gas escaping from reflux apparatus’ top or apparatus was not fully closed so that some of the heat escaped and did not proceed the reaction well‚ leaving reagents. Another source of error could be that some of the organic layer could have been transferred along with the aqueous layer when the aqueous layer was getting separated from the organic layer by a pipette.
