Aspirin is the common name given to acetylsalicylic acid‚ sometimes abbreviated as ASA. ASA is considered to be an organic acid since it is composed of Carbon‚ Hydrogen‚ and Oxygen which also contains the carboxyl functional group-COOH. Pure ASA can be synthesized by treating salicylic acid with acetic anhydride in the presence of a trace of either sulfuric (in our case) or phosphoric acids. The complete reaction of ASA is shown in Figure 1.1 on page 2. Figure 1 shows the reaction for the synthesis

is made by reacting salicylic acid (week 1) with excess ethanol. An acid catalyst is also needed. salicylic acid (SA) ethanol ethyl salicylate (ES) The overall yield is determined from multiplying yields of the two reactions: 1. ASA + HCl(aq) →SA and 2. SA + ethanol → ES + water Apparatus The reaction takes place by refluxing (gentle boiling) in a 100-mL round bottom flask. This time the ice-cooled condenser is essential‚ otherwise the ethanol reactant (b.p

In addition‚ we skipped the qualitative test of our purity for SA and Aspirin (ASA). The first part of this experiment is the preparation of ASA from SA were‚ we prepared our aspirin from the collected salicylic acid. A screw-capped vial was weighed empty to 29.7416 grams and filled with SA. The mass recorded of SA was 1.3995 grams of SA and it was weighed and

What is acetylsalicylic acid? Acetylsalicylic acid (ASA)‚ or more commonly known as aspirin‚ is a medication that can be used for pain‚ fevers‚ and inflammation. It can be used for long periods of time‚ in small amounts‚ to prevent heart attacks‚ strokes and the formation of blood clots. A heart attack victim can be given a low dose right after the ordeal to reduce the risk of another one. Side effects of this drug is ulcers‚ internal bleeding (stomach) and ringing in the ears.
