Substances amount of Panacetin(g) to begin with: 3.00g filter paper weight: 0.92g amount of aspirin (g) recovered from mixture: __0.76g(wet) 0.66g(dry )_______ amount of sucrose (g) recovered from mixture: __0.28 g_______ amount of dry crude unknown component (g) recovered from mixture: _1.09 g________ Total amount of substances recovered: 2.03 g Percentages of Substances from Total Amount Sucrose: 0.28/2.03= 13.8% Aspirin: 0.66/2.03= 32.5% Unknown: 1.09/2.03= 53.7% Melting point data mp of recrystallized unknown component: __110 C_______ mixed with acetanilide: __110 C__ mixed with phenacetin: ___80 C__ identification of unknown component: ____acetanilide_______ IV. Discussion: The purpose of this experiment is to analyze the drug preparation of a component called “Panacetin” by finding out what percentages of aspirin, sucrose, and the unknown component it contains. The unknown component is believed to be either acetanilide or phenacetin. To obtain
