Experiment 12: Isopentyl Acetate 19 October 2012 Introduction: The purpose of this experiment is to prepare isopentyl acetate by direct esterification of acetic acid with isopentyl alcohol. After refluxing there is an isolation procedure where excess acetic acid and remaining isopentyl alcohol are easily removed by extraction with sodium bicarbonate and water. The ester is then purified by simple distillation and the IR is then obtained. Techniques and equipment used throughout the experiment

Zinc Reacts with Vinegar’s Acetic Acid To Produce Electricity March 7‚ 2014 Abstract This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce

Analyze energy sources and transfers of heat. 3.8.10A Analyze the relationship between societal demands and scientific and technological enterprises. Content Objectives Students will know that 1. Acetic acid reacts with sodium bicarbonate to produce a gas. 2. Acetic acid and sodium bicarbonate are the chemical names for vinegar and baking soda‚ respectively. 3. The two main purposes of an air bag are to slow a person’s forward movement into the steering wheel (or dashboard)

boats and an electronic scale. We poured the NaHCO3 from the plastic weighing boats into their own plastic bags. Using the measurements of the NaHCO3 ‚ we calculated the exact volumes of 6.0 M acetic acid needed to completely react with the amounts of NaHCO3 (see Calculations). The acetic acid was then measured out using 10 mL graduated cylinders and poured into their respective locations in the plastic bags. Once all of the reactants were placed into their correct positions‚ the bags were

continued to decrease primarily as a result of less consumption for acetic acid manufacture‚ as the industry continues to move toward the more efficient and lower-overall-cost carbonylation-of-methanol process. For example‚ all manufacture of acetic acid from acetaldehyde in North America has been discontinued and in Europe significant capacity for this process has been permanently shut down. Acetaldehyde use for acetic acid manufacture in Asia continues but is under pressure from the ongoing

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

Procedure/Observations: 1. Weigh out ~280 mg of acetanilide in a 10 mL r.b. flask with a stir bar. 2. Then‚ add 2.0 mL of glacial acetic acid using a calibrated Pasteur pipet. 3. Stir the mixture until all of the acetanilide has dissolved. It may be necessary to add more acetic acid dropwise until full dissolution has occured. 4. In the fume hood‚ add 0.6 mL of 4.1 M bromine solution in acetic acid. 5. Cap the round bottom flask before returning to the bench. 6. For 15-20 minutes‚ stir the reaction mixture

CHAPTER 1 Introduction Background of the Study Like many other hygiene convenience‚ shoe polish or can also be called boot polish is usually a wax ‚ cream or paste used by people to shine‚ water proof and restore the appearance of leather shoes. This extends the footwear’s life. This is made up of many kinds of chemicals and because of this; it can cause irritations‚ allergies to us. In our generation‚ shoe polish is used every day and companies produce a lot of it to meet the demands of

see how given amounts of sodium bicarbonate reacts with acetic acid and see how it creates different amounts of new compounds. Procedure: In this lab‚ we were going to be reacting 12.5g sodium bicarbonate with 7.4mL acetic acid. Before we began‚ we turned on the hot plate to a medium level‚ allowing it time to heat up. While the plate was heating‚ we gathered 1 1/4g sodium bicarbonate onto the balance. Next‚ we measured 7.4mL acetic acid by pouring it into a 10mL graduated cylinder. Once we had

The combined annual production in 1985 of Japan‚ North America‚ and Europe was about 400‚000 tons.[1] In 2004‚ an estimated 1.3M tons were produced worldwide.[2] Production Ethyl acetate is synthesized in industry mainly via the classic Fischer esterification reaction of ethanol and acetic acid. This mixture converts to the ester in about 65% yield at room temperature: The reaction can be accelerated by acid catalysis
