Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in

Grignard Synthesis of Triphenylmethanol Aim The aim of this experiment was to prepared Grignard reagent (phenylmagnesium bromide) from bromobenzene and magnesium‚ to use the reagent prepared to synthesise a tertiary alcohol (triphenylmethanol) by reacting reagent and ester (methyl benzoate)‚ and the product formed is analyse by infrared spectroscopy (IR)‚ melting point‚ thin layer chromatography (TLC)‚ gas chromatography mass spectrum (GCMS) and finally Nuclear Magnetic Resonance spectroscopy.

has changed and now friends can instantly communicate at the touch of a button. This transition to electronically communicating has negatively impacted the United States Postal Service due to the loss of business. Therefore‚ it is imperative that the USPS reinvents itself as well as adapts to the new technology era for the company to avoid bankruptcy. One action the United States Postal Service can take to save money is stopping saturday deliveries. These deliveries will merely be set aside and delivered

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

Synthesis of Aspirin Ling Tecson Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order

First‚ the synthesis of the coordination compound‚ KaFeb(ox)cdH2O‚ needed to be carried out. This was achieved by weighing out 8.29 grams of K2C2O4 with a Dial-a-gram balance. Once measured‚ the 8.29 grams K2C2O4 were placed in a 125 mL Erlenmeyer flask. 25 mL of deionized water were then added to the 125 mL flask and stirred with the K2C2O4 until complete dissolution was achieved. Next‚ 4.11 grams of FeCl3 were weighed out using the balance previously mentioned. Once the 4.11 grams were measured

Case study Freud carried out a number of case studies‚ finding out from clients what was causing them problems or holding them back. They may have symptoms (e.g. phobia) that arose from the unconscious. E.g. Little Hans case study. Activation-synthesis theory of dreaming – Hobson and McCarley 1977 1.

sulfate to potassium chromate formed a yellow coloured solution and when base was added‚ the solution turned into a bright yellow colour. This was difficult to observe as the colour change was very subtle‚ however‚ interpretation was manageable as pH paper was used to find when the addition of base should be stopped. Chromium oxide green was synthesized from the reaction between potassium dichromate and sulfur. The reaction involved heat thus‚ sulfur dioxide gas was released and colour change was observed
