Preparation of aspirin 1 purpose: the purpose of this experiment is to prepare acetylsalicylic acid, aka aspirin introduction: an important part of chemistry is the preparation, or synthesis, of compounds from simpler start. Preparation of acetylsalicylic acid (aspirin) background figure 5: the aspirin synthesis reaction safety the chemicals used to synthesize aspirin present a health hazard and exposure should be kept to a filtration apparatus as shown in the figure to the right 9 weigh a piece of filter paper on a watchglass. Aspirin synthesis hplc analysis e4 - aspirin synthesis hplc analysis the use of salicylic acid was discontinued after the synthesis of aspirin its strong acidity had a series of side effects, mostly irritating the mucous membranes of the mouth and stomach for the separation of nonvolatile and thermally unstable compounds in an. Lab report introduction this lab has the following two concepts: synthesis of acetylsalicylic acid and analysis of acetylsalicylic acid synthesis is a purposeful execution of chemical reactions to obtain a product this concept is used in the first part of the lab when we have to produce crystals of aspirin analysis is the separation, identification, [.
Separation of acetaminophen and 4-aminophenol on primesep c acetaminophen and 4-aminophenol ar both aminophenols acetominophen or paracetamol is a widely used analgesic and antipyretic 4-aminophenol is an intermediate in the synthesis of paracetamol and used in photography as a developer. E29 preparation of aspirin (acetylsalicylic acid) and thin-layer chromatography of analgesic drugs the task to prepare a pharmaceutical compound and test its purity. To avoid weighing out individual portions of solids as small as 10 mg, prepare standard solutions of aspirin and caffeine in methanol, add the appropriate volumes, then enough methanol to reach about 30 ml.
• materials and methods: this experiment called for the synthesis of acetylsalicylic acid, or aspirin, by using salicylic acid, acetic anhydride, sulfuric acid, and vacuum filtration the salicylic acid and the acetic anhydride were mixed in a flask. In addition, the separation abilities were investigated by using hplc analysis, the adsorption of templates (aap and as) and of its structural analogue, the selectivity factor (α), and the imprinting-induced promotion of binding (ipb) the results of the analysis revealed that the prepared mips have high separation abilities and selectivity.
