Organic Synthesis Experiments. Do not use this medicine on a child or teenager who has a fever, flu symptoms, or chickenpox.
Aspirin Melting Point Lab
When the aspirin was prepared, it was isolated and filtered. The percentage yield of the synthesis was calculated to be The mixture was warmed over a water bath for 5 minutes while stirring. After warming, 20 drops of distilled water was slowly added. It was allowed to cool and was placed in an ice bath until the solution becomes cloudy. Using pre-weighed filter paper, the mixture was filtered and was allowed to dry in the filter paper.
In determining the melting point range of the aspirin, a capillary tube sealed at one end was one-third-filled with the dried aspirin. The capillary tube and a thermometer were immersed in an oil bath. The temperature at which the solid started to melt and the temperature when the entire sample was completely liquefied were recorded as the melting point temperature range. Purification was necessary to remove any unreacted salicylic acid and acetic anhydride as well as the acetic product and phosphoric acid. Acetic acid and phosphoric acid are water soluble so they were removed by.
Get Access. If you do continue to take the dispersible form it is important to start taking them dispersed in water because this means that the aspirin will not concentrate in one part of your stomach, which would be more likely to cause side effects. The percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage. Think of percent yield as a grade for the experiment: 90 is great, very good, good, acceptable, poor, very poor, etc. What is the purpose of synthesizing aspirin? Category: business and finance commodities. Synthesis and Characterization of Aspirin. The purpose of this lab was to synthesize Aspirin and measure the synthesized Aspirin's purity. By calculating the theoretical yield based on the original amount of Salicylic acid, one could determine the actual yield percentage of the reaction.
