We suspect that this unknown compound is either acetanilide or phenacetin. From the solubility of acetaminophen and phenacetin‚ we could know both of them are relatively soluble in boiling water but insoluble in cold water so that we took the recrystallization as the method to purifying the unknown component.

Suppose you were performing a recrystallization and you had just added the optimal amount of boiling solvent to dissolve your impure solid…but then you a squirrel ran by and you decided to chase it. When you got refocused and returned to your experiment‚ you realized that you’d left your Erlenmeyer flask containing your recrystallization solution on the hot plate for too long.

Esteva Group 4 2B Medical Technology Organic Chemistry Laboratory ABSTRACT In this experiment‚ acetanilide was used as the pure organic compound. Acetylation of aniline and acetic anhydride yields the crude product or crude acetanilide. The crude acetanilide was purified by dissolving it in hot water and then the solution was cooled slowly by placing in

RECRYSTALLISATION PRESNTED BY Mariam SeiduPriscilla TweneboahEvans Appiah-Kubi 3796509 Yaw Adu PokuEric Adjei 3809009 INTRODUCTION Recrystallization is a method of purifying a solid. There are two types of impurities: those more soluble in a given solvent than the main component and those less soluble. (If there are any impurities that have the same solubility as the main component‚ then a different solvent needs to be chosen.) When organic

The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base properties.

The label reveals that Panacetin is composed of sucrose (10%)‚ aspirin (40%)‚ and Tylenol (50%). Although this information is reported‚ the true composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin‚ Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable in identification
