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

enantiomer of the molecule Naproxen is used to treat arthritis pain but the other enantiomer causes liver poisoning. With such high stakes‚ it is easy to see the importance of being able to create molecules in the exact way necessary to yield the desired effects. Therefore‚ it is necessary for synthetic chemists to have reagents that allow them to be selective in their manipulation of a molecule‚ be it in oxidation‚ reduction‚ or in the addition of a functional group. In this lab we will examine the

In George Orwell’s dystopic novel 1984‚ the citizens of Oceania are unfortunately controlled by the Party in every way possible. The

They then examined these samples through the SEM‚ XRD‚ and TGA to learn more about the properties and differences. The SnSp (powdered) species came from the SnSg (granular) synthesis during solvent exchange and the CO2 supercritical drying process. They found that the PAN hybrid was very much more mechanically stable than pure chalcogel‚ even though the as-made chalcogels adsorbed iodine more quickly‚ and more effectively. The sorbents that contained more Sn2 S3 took in more iodine than others
