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%). Palmitic acid and oleic acids were the major fatty acids of the

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).

CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID:

More specifically‚ when simple compounds containing hydroxyl and carboxylic acid moieties are dissolved in water and dried at elevated temperature under acidic conditions‚ esters can be formed. ψD was designed so that intramolecular esterification (i.e.‚ a lactonization) is possible.

Background information: Glow sticks are made of hydrogen peroxide‚ a phenyl oxalate called ester‚ and phosphorescent dye. The ester and phosphorescent dye are kept in one part of the glow stick‚ the hydrogen peroxide in the other‚ separated by a piece of glass. No chemical reaction occurs until the glass breaks‚ combining the chemicals together inside the tube
