Synthesis of Isopentyl Acetate Abstract The purpose of this experiment was to produce isopentyl acetate‚ banana oil. Acetic acid and isoamyl alcohol were used to synthesize isopentyl acetate. The techniques used for the separation and purification of isopentyl acetate were reflux‚ liquid-liquid extraction‚ neutralization and distillation. The identification of isopentyl acetate was based on boiling points and an infrared spectrum. This experiment resulted in a 11.68% yield. The reactants

In fact‚ “caffeine is the most consumed psychoactive substance in the world” (Ruxton How is this instead (Caffeine is especially common throughout…) 15). It is found very especially commonly throughout every day foods and consumed mostly though through coffee‚ tea‚ soda‚ and chocolate (Spiller 200). Many Americans

in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group

Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

SYNTHESIS OF THE PHARMACEUTICAL ASPIRIN (ACETYLSALICYLIC ACID) AIM: The aim for this experiment was to synthesise a small amount of aspirin with salicylic acid as the starting product and sulphuric acid as the catalyst. The product obtained from this reaction will be impure and will need to be purified. This will be done by recrystallization. We will then record the products’ melting point and calculate the yield in order to determine the degree of purity of the aspirin sample. Diagrammatic scheme

DNA synthesis inhibitors Nucleic acid inhibitors are chemicals which inhibit the production of nucleic acids including both DNA and RNA. DNA and RNA inhibitors inhibit enzyme action in DNA replication in the same way as the topoisomerase inhibitors we discussed earlier. Topoisomerase inhibitors (1) (10) are chemicals which interfere with the enzymes that allow DNA strands to separate and to re-join‚ a process that is required for the division of bacteria and without which DNA cannot effectively
