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
