VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below

use of catalysts while minimizing potential chemical accidents. Results and Discussion The Oxone epoxidation reaction is a two-step mechanism that includes forming the dioxirane first. The second step is using the dioxirane to attack the trans-anisole. The mCPBA reaction is a one step that forms the trans-anethole oxide. The result of the Oxone epoxidation reaction yielded 0.96 g of product which was 65% yield. The result of the mCPBA epoxidation reaction yielded 1.03 g or product which was 70%

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

Acetylation of Ferrocene 17. October 1996 Experiment #7 Introduction In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process had worked we employed: IR spectra analysis‚ column chromatography‚

Euthanasia: The Debate of Legalization Euthanasia is derived from the Greek word that ultimately means “good death”(Ahmed‚ 2012). The dispute surrounding euthanasia has been an on going argument for many decades. Society has always indicated mixed feelings regarding this controversial subject. The government allows humanity to euthanize animals‚ especially the terminally ill. A human’s life should be looked at in the same context‚ because no one should be left to live in pain or suffering.

Chem 3418 Organic Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the
