Aspirin

Synthesis of acetylsalicylic acid (Acetylsalicylic acerbic) Objective: * To synthesize aspirin wage salicylic Acid and acetic anhydride. * To calculate %yield of aspirin. Theory: * acetylsalicylic acid is the most common salicylate. It is an analgesic, antipyretic and anti-inflammatory drug that is utilise in medicine nowadays. * The process involves mixing salicylic acid with acetic anhydride in a mixture while adding heavy sulfuric acid (catalyst). * A uprising in the temperature is observed indicating that the reply is taking place. Upon the drop of this temperature the reaction is close to completion. * %yield = [mass(actual) mass( hypothetic) / mass( hypothetic)] x100 discernible: 1. Erlyne Meyer Flask 2. Beakers 3. Spatula 4. Digital balance 5. Ice bath 6. suck filtration apparatus 7. Funnel paper Procedure: 1. In an electric potential add 3g of salysilic acid. 2. Add 6mL of acetic anhydride. 3. Add 10 drops of concentrated sulfuric acid. 4. Stir the mixture continuously for 10 minutes. (note the rise in temperature) 5. Add 50mL of cold water when the temperature decreases fully. 6. aplomb in ice and then filter using sucking filtration. 7. study the mass of the aspirin.

Table of Data: Reagent| Molar bunch (g/mol)| Grams (g)| Moles (mol)| Salicylic Acid| 138| 3.06g| 0.022| Acetic Anhydride| 102| -| -| The limiting reagent is Salicylic Acid since in the science testing ground manual it was given that acetic anhydride is in excess. Therefore, the mass of theoretical Aspirin = 3.06g (1:1! ratio/stoichiometry) Calculations: n (salicylic acid) = m/MM = 3.06/138 = 0.22 mol * n (aspirin)theoretical = 0.22 mol m (aspirin)theoretical = 3.06 g Questions: 1. The dross most apparent present would be salicylic acid. If consumed by globe it would cause monetary value to the stomach and digestive placement due to high acidity. 2.
