Extraction and Evaporation: Separating the Components of "Panacetin"
Extraction and Evaporation: Separating the Components of "Panacetin"
Submitted- July 17, 2012 Introduction The purpose of this lab is to investigate the composition of a compound suspected to be Panacetin, a type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. 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. Then, the percent composition of Panacetin can be deduced based on the masses of the three dried components. The compounds being studied are as follows:
Calculations
Theoretical Percent Recovery
• .4015 g sample of Panacetin composition: 10% sucrose, 40% aspirin, and 50% unknown
Theoretical Composition Percentages:
• .4015(10%)=0.0400 g of Sucrose
• .4015(40%)=0.1606 g of Aspirin
• .4015(50%)=0.2001 g of acentanilide or phenacetin

Percent Recovery
• Figure 1. (.060g sucrose + .091g aspirin + .125g unknown) / Original Mass of Panacetin(.4015) x100 = 68.74% yield
Composition Percentages
• Figure 2: Sucrose: 0.060/.276 = .2174 x 100 = 21.74% Aspirin: 0.091/.276 = .2529 x 100 = 32.97% Unknown: 0.125/.276= .4789 x 100 = 45.29%
