Find A … In 1899, Heinrich Dreser, a top chemist with Friedrich Bayer and Co., gave acetylsalicylic acid the now familiar name aspirin, but in 1897 Bayer didn't think aspirin had much of a future. Wear heat-protective gloves when handling hot equipment. The methods used included recrystallization and scratching to produce a precipitate, which was then filtered to remove any excess moisture. Balance the equations and identify the type of each reaction as: combination decomposition, single replacement, double replacement, or combustion. 4.

The excess acetic acid will be quenched withthe addition of water. In thisexperiment, phosphoric acid will be used as the catalyst. There is also a great similarity between acid anhydrides and acyl chlorides (acid chlorides) as far as these reactions are concerned. Balance the equations and identify the type of each reaction as: combination decomposition, single replacement, double replacement, or combustion. These reactions are all considered together because their chemistry is so similar. How the COVID-19 Pandemic Will Change In-Person Retail Shopping in Lasting Ways. The reaction for the synthesis is given below. Here limiting reagent is salicylic acid; hence yield should be calculated from its amount taken. | MyTutor. The purity of the sample will then be ana-lyzed using TLC. acetylsalicylic acid (aspirin) see equation 1. How is it produced in industry? The byproduct is acetic acid. Ethanoic anhydride is corrosive. The mechanism for the synthesis of aspirin using Salicylic Acid, Acetic Anhydride, Acetylsalicylic Acid, and Acetic Acid. Actual Yield = weight of desired product 3.) Flashcards. Experiment 8 – Synthesis of Aspirin Aspirin is an effective analgesic (pain reliever), antipyretic (fever reducer) and anti-inflammatory agent and is one of the most widely used non-prescription drugs. Concentrate on these similarities as you go … Another chemical test that will differentiate the synthesized aspirin from the commercially-available aspirin is iodine test. 1 However, salicylic acid also has an electrophilic carbon atom as part of its carboxylic acid functional group. Molecular weight of salicylic acid = 138 g/mole. 3623 mol + 0. Calculate the theoretical yield for aspirin. The first of these that is used is the procedure of weighing by difference. Aspirin Synthesis Materials . acetylsalicylic acid (aspirin) see equation 1. For the synthesis of aspirin, how do you calculate the percent yield if the reaction produces 4.70 grams of aspirin. 3.0 g salicylic acid; 6 mL acetic anhydride* 5-8 drops of 85% phosphoric acid or concentrated sulfuric acid* Distilled water (about 50 mL) 10 mL ethanol; 1% iron III chloride (optional, to test purity) *Use extreme caution when handling these chemicals. The chemical equation for the synthesis of aspirin is C7H6O3 + C4H6O3 –> C9H8O4 +C2H4O2, which is a reaction of salicylic acid with acetic anhydride in the presence of phosphoric acid.
