Rebecca Boreham 7/1/14 Chem 2423 Experiment #5 Synthesis of Aspirin Elizabeth Ajasa Kaylee Seymour Lauren Hatfield Suveda Perikala Introduction/ Purpose Aspirin is the most commonly used drug in the United States. Forty million pounds are produced each year. The chemical name for aspirin is Acetylsalicylic acid. Aspirin is a pain reliever and a fever reducer. Aspirin originated from the bark of a White Willow Tree. Chewing the bark however is extremely acidicand irritates the mucous membranes

concentration of NaOH from 0.5M to 1M‚ then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL of Acetic Acid at 50% (10 mL per

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together‚ and then acidified by the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation was salicylic acid. After

claimed is: 1. A method of producing an organic fertilizer by using fish‚ said method comprising the steps of preparing a raw material containing more than 80% of fish heads‚ boiling the raw material to obtain a stock‚ removing solids and oil contents from the stock to obtain stock liquid‚ thereafter treating the stock liquid in a decomposition tank with decomposing enzyme for enzyme decomposition‚ filtering the enzyme-decomposed stock liquid to produce a clarified liquid organic fertilizer‚ and condensing

purpose of this essay is to discuss the Islamization of Persia in relation to the Samanid and Buyid Dynasties. The synthesis of Persian culture and Islam was not an immediate result of the Arab expansion into Iran and there is certainly a lack of research on the subject. However‚ in this essay‚ I will attempt to explain the contributions of the Samanid and Buyid dynasties to this synthesis with a focus on the attempts of the Samanid Dynasty at centralization and a unified identity through religion‚ language

particularly fruit flavors -- have just one or a few dominant chemical components that carry the bulk of the taste/smell signal. Many of these chemicals are called esters. Esters have the structure of -COOR. Instead of the alcohol portion of thecarboxylic acid (-COOH)‚ there is an ether portion. The low boiling‚ volatile esters are known for their "fruity" smell and flavor. They are used in artificial flavorings. (Operational Organic Chemistry‚ John W. Lehman‚ Third Edition‚ Prentice Hall‚ 1999). The preparation

Lab E: Adapted from Experiment #10 TA: Sudipta Biswas Tuesday‚ 1:05pm 10/25/11 Sarah Kempkes Abigail Scherer Abstract: The purpose of this experiment was to create and obtain pure acetaminophen. p-aminophenol and acetic anhydride were used to create acetaminophen and acetic acid. The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure

at too. I HATE doing the reference page!! I always seem to mess something up! LOL and some teachers can be pickier then others …… But GOOD LUCK and I hope this helps…Let me know if you need anything else Final Synthesis Paper Danielle Sisel March 4‚ 2013 LAS 401: Synthesis and Servant Leadership When I first came to Silver Lake College I didn’t know what to expect.
