The initial observation is of the solid p-aminophenol, white fine-grained powder, and with the addition of water forms a cloudy white solution. When dissolution occurs following the addition of acetic acid a clearer mixture can be observed. Stirring and heating forms a gelatinous precipitate and you can feel the solution thicken whilst stirring. The precipitated solution undergoes vacuum filtration where a white solid like substance remains. During the recrystallization process, the white powder is again dissolved in water according to the mass obtained and until a clear solution is attained, the solution is heated. The crystallization process is slow however crystal solids can be seen during precipitation. The filtered end product is a fine grained powder again and a melting temperature of 165 can be observed.BACKGROUND Principle: Methyl salicylate (oil of wintergreen) is an organic ester.

In terms of our purpose of identifying the product as acetaminophen, the melting point determination encourages our confidence in supporting the theory. The crude product obtained a value of 94 in the MelTemp apparatus indicating a high amount of impurities however; the final pure product is similar to the theoretical melting point. Although acetaminophen is harmless in small doses, it can cause liver damage if taken incorrectly Acetaminophen (USAN) or paracetamol (International Nonproprietary Name) is a popular analgesic (pain-controlling) and antipyretic (fever-reducing) drug that is used for the relief of headaches, fever, and minor aches and pains, such as pain in joints and muscles You probably remember amines are more basic than alcohols, but for the same reasons amines are also better nucleophiles than alcohols.

0mL of pure acetic anhydride will be added to dissolve the p-aminophenol. Following this there will be continuous heating in the regulated water bath to ensure all p-aminophenol dissolves. Gradual cooling will lower the mixtures temperature to room temperature followed by further cooling in an ice-water bath. The mixture will begin to precipitate out a solution.The theoretical value for the melting point of Acetaminophen in accordance to the CRC Handbook of Chemistry and Physics provides a value of 170 whereas the value we observed was 165. The pure value is relatively close to the theoretical value and this helps identify the product as acetaminophen.
As the percent yield was 27.39% the low crude solid temperature could support the high impurity level in the sample. During the recrystallization the impure sample could have been extracted resulting in a low yield. Also the time limitation could have reduced the amount of precipitation during the experiment.
