Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

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

Once the aspirin is prepared‚ it is isolated from the reaction solution and then it is purified. The aspirin is insoluble in cold water‚ and it is isolated by filtering the chilled reaction solution. Purification is essential to remove any unreacted salicylic acid and acetic anhydride as well as the acetic acid product and phosphoric acid. Acetic anhydride is caused to decompose by the addition of water once the formation of aspirin is complete. C4H6O3 (Acetic anhydride) + H2O (Water) ------------------------->

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

Synthesis of Benzoin Date of Experiment: 1-26-15 Chelsea Price Lab Partner: Joey Simmons Abstract: In this experiment‚ benzoin was synthesized from benzaldehyde‚ using thiamine hydrochloric acid as a catalyst. The thiamine HCl was deprotonated by sodium hydroxide and acted as a nucleophile to attack the benzaldehyde. A water-cooled condenser was used to heat the solution at reflux. Vacuum filtration was used to wash and dry the product. The benzoin product was recrystallized

Multistep Synthesis of Benzilic Acid The synthesis of several complex organic compounds follows a multistep synthesis. "Multistep synthesis" refers to the procedure in which the product of one reaction serves as the starting material in the subsequent reaction. The multistep synthesis of benzilic acid begins with a conversion benzaldehyde to benzoin through a condensation reaction. The benzoin then oxidizes into benzil‚ which undergoes rearrangement to give benzilic acid. Benzoin Synthesis * When

In this lab we employed various assays utilizing a biuret reagent‚ coomassie brilliant blue reagent‚ and ultraviolet light in order to determine the identity of six unknown solutions and the concentration of a bovine serum albumin sample. We were given three samples that lacked protein‚ and three samples containing proteins‚ and using a spectrophotometer we assessed the amount of light absorbed versus the light transmitted‚ based on the principles of the Beer-Lambert Law. The three proteins used

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
