The purpose of our experiment was to synthesize aspirin from acetyl anhydride‚ salicylic acid‚ and sulfuric acid. And then determine the relative purity of the synthesized sample. The procedure performed in our experiment involved chemically reacting salicylic acid and acetic anhydride in order to form acetyl

Reactions: Procedure: Refer to Pavia‚ et. al.‚ Introduction to Organic Laboratory Techniques; 4th ed.‚ Thomson Learning‚ pp. 82-86 Procedure Modifications: In the Initial Preparations steps we used capillary tubes rather than preparing capillary micropipets to spot the plates. We used 5cm x 20cm TLC plates instead of 6cm x 10cm plates;

components of a simulated preparation‚ panacetin and making use of its acid base properties. To obtain such a pure compound‚ the compound we want must be separated from its other natural components‚ which can be done by manipulating physical and chemical properties. Panacetin contains sucrose‚ aspirin and an unknown which can be acetanilide or phenacetin in which phenacetin was created and weighed. Introduction In this lab our basic goal was to make the sucrose‚ aspirin and unknown that are formed

Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group into an acetyl group‚ (R—OH → R—OCOCH3)

This laboratory has its first objective to familiarize with the thin layer chromatography (TLC) technique. Second‚ each student has to identify the unknown components by comparing it to one of the tree dissolved liquid analgesics: Acetaminophen‚ Aspirin and Caffeine. Finally‚ calculating the Rf value by measuring the mobile and stationary phase. Chromatography is a technique used to separate mixtures into their compounds. It’s based on a mobile phase and a stationary phase. The mobile phase moves

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
