Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

purpose of this experiment was to prepare the Grignard reagent methylmagnesium iodide and react it with benzoin to form the 3o alcohol 1‚2-diphenyl-1‚2-propanediol‚ through an addition reaction pathway. Introduction: Grignard reagents are alkyl or aryl-magnesium halides that act as the nucleophile in Grignard reactions‚ where ketones are reacted with the reagent‚ then treated with acid to produce an alcohol. In the case of this experiment‚ methylmagnesium iodide was created from methyl iodide and

2L Date Submitted: March 12‚ 2012 MIXED-ALDOL CONDENSATION Synthesis of Cinnamaldehyde I. Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde‚ 4-5% sesquiterpenoids (α-humulene‚ β-caryophyllene‚ limonene and

This experiment involved a substitution reaction to perform synthesis of 2-phenylethanol to get (2-bromoethyl)benzene. Using NaBr in an acidic solvent of H2SO4 with H2O present‚ this synthesis was possible. Subsequent evaluations using TLC and then analyzed samples by Gas Chromatography were done to evaluate the results. Using SN2 reactions‚ primary alcohol is going to be converted to alkyl halide. Since the reaction can be reversed‚ the strong sulfuric acid was to make sure the product would indeed

Experiment 5 In the first part of this lab‚ the objective was to get the molar concentration of sodium hydroxide by using the secondary standard‚ sodium hydroxide solution with the primary standard‚ potassium hydrogen phthalate. With this information‚ we could create a second derivative plot‚ which can be used to obtain the exact concentration of the secondary standard‚ sodium hydroxide. Also‚ the indicator can give us these results along with the end points and with the readings from the pH meter;
