    The procedure of the experiment includes two parts: 1. Determination of the Freezing Point of Glacial Acetic Acid: to record the temperature of acetic acid every 30 seconds until it reach 300 seconds (5 minutes). 2. Determination of the Molar Mass of an Unknown Compound: to record the temperature of the mixture between unknown solid and glacial acetic acid. After that, put the ice-water mixture into the tube and record the temperature every 30 seconds. Pre lab questions: 1. Solute: dissolved…

    Ethylene Case Study

    • 1030 Words
    • 5 Pages

    Results Unit 800 produces ethylene and acetic acid through the partial oxidation of ethane. Ethylene, the most abundant product from the unit, is partitioned such that half of the product is used as a feed source for Unit 600 and the other half is sold on the market. Ethylene purity must reach at least 99.5% to be sold as reagent grade. The second desired product, acetic acid, is also sold on the market, at 99% purity. Unit 800 consists of a fired heater to preheat the reactants, an…

    This objective was accomplished when the researchers synthesized esters of raspberry, banana and peach through reacting indicated alcohols and carboxylic acids in the presence of an acid catalyst in a round bottom flask and reflux condenser. This enabled the researchers to synthesize the following esters: pentan-2-yl acetate, benzyl acetate, butan-2-yl methanoate. The researchers, however, were unable to purify the said crude product due to the instructions given to them by their…

    Anti Bumping Lab Report

    • 1691 Words
    • 7 Pages

    Results/Discussion: 2-butanol and Acetic Acid were refluxed together with anti-bumping granules and a catalyst of sulphuric acid for 1 hour and five minutes. Anti-bumping granules are small ceramic granules which have rough edges. They are added within a mixture to encourage smooth boiling. In this experiment by adding the anti-bumping granules we were able to achieve smooth boiling throughout both the reflux process and the distillation process. Without adding these granules, bubbles of vapour…
