EXERCISE 11 Synthesis of Aspirin (Acetylsalicylic Acid from Salicylic Acid) RAQUID‚ Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound

any equations that may be encountered and go over their derision. Methodology: Reference the lab manual here. If you made any changes to the experiment make note of them here. Also list any precautions one should take with the chemicals being used. Give a brief overview of the procedural steps (others must be able to follow) Data: Place any measured values or observations made during the lab in this section. Include any known values that were looked up (don’t forget a reference for them)

1. In the Luminol synthesis the compound being oxidized was the sodium hydrosulfite. 2. The purpose of the acetic acid is to pronate the dianon organic molecule to make the neutral organic compound‚ Luminol that will crash out of the solvent. If the number of moles were reversed for acetic acid and sodium hydroxide the solution would be very basic‚ and and the amount of Luminol produced would decrease. 3. The cold water was used to decrease the solubility of Luminol in the solvent and prevent further

the level of “greenness” of a chemical reaction‚ or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic‚ coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck and Stille reactions. Palladium typically exists in the oxidation

Proteins are arguably the most important things that people know the least about. As OpenStax CNX puts it‚ “Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins.

experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible error

Tie-Dye Grignard Synthesis Abstract: 4-Bromo-N‚N-dimethylaniline underwent a Grignard reaction with diethyl carbonate to produce a type of the tie-dye chemical triarylmethane. This specific triarylmethane produces a vivid crystal violet color when dyed. The experiment was first heated under reflux to produce the necessary Grignard reagent as a grey liquid. It was then reacted with diethyl carbonate and hydrochloric acid to produce crystal violet. The resulting chemical was very absorbent to

Commercial Aspirin Tablet Analysis Tuesday Evening Intro: The purpose of this lab was to analyze commercial aspirin tablets. To do so‚ the percent acetylsalicyclic acid (active ingredient) in tablets using acid-base titration was determined‚ the percent acetylsalicyclic acid in tablets by formation of a colored iron(III)-salicylate complex was determined using spectrometry‚ and then the percents from each process was compared. Acetylsalicylic acid is produced when salicylic acid and acetic

For this lab‚ 40.2 mL of canola oil were used as the initial volume for the production of synthesized biodiesel. Through the synthesis process‚ 31.307 grams of canola biodiesel was produced‚ which is a percentage yield of 85.714%. In order to get this percentage yield‚ the following calculations were made: 40.2 mL canola oil × 0.9073 g1 mL=36.5 g × 1 mol376.6 g=0.0416 moles canola oil From the prelab‚ for every 1 mole of oil‚ 3 moles of biodiesel are produced. 0.0416 mol oil × 3 mol biodiesel1

IR ATR spectra of the solid complex was acquired along with a solution cell IR of the complex in methylene chloride. According to the lab manual used for this experiment two characteristic carbonyl IR stretches of MesMo(CO)3 occur strongly around 2000 cm-1. The stretches at 1940 and 1855 cm-1 in the IR ATR spectra are possible indicators of carbonyl stretches in the compound that was
