    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
