Experiment 2: Synthesis of Isoamyl Acetate (Banana Flavor) Paul Symon C. Manuel*‚ Katherine Merene‚ Charlene Mondelo‚ and Pamela Mallari Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract: The purpose of this experiment was to synthesize isoamyl acetate via an esterification reaction between acetic acid and isoamyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water‚ and then dried

Nitration of Methyl Benzoate Abstract: This procedure demonstrates the nitration of methyl benzoate to prepare methyl m-nitrobenzoate. Methyl benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction‚ in which the nitro group replaces a proton of the aromatic ring. Following recrystallization‚ melting point and infrared

Gas chromatography (GC) was used to determine the fatty acid composition of the triacylglycerol‚ sterol esters and phospholipids where it showed that 80% of the triglyceride composition was trilinolein (31.3–32.2%)‚ oleo dilinolein (31.0–34.0%) and palmitoyl dilinolein (14.9–22.3%).

metabolic pathway of cocaine administrated. Cocaine is largely metabolized into two major metabolites benzoylecgonine (BE) and ecgonine methyl ester (EME) and two minor metabolites norcocaine (NCOC) and m- and p-hydroxycocaine (OH-COC) (Goldstein et al.‚ 2009). Benzoylecgonine is primarily produce in the liver by human carbozylerstrase type 1‚ ecgonine methyl ester is formed in the liver by human carboylestrase type 2 and by pseudocholinestrase known as butyrlcholineetrase (Zhang & Foltz‚ 1990).
