Andrew Klingsporn Organic Chemistry Lab 1-703 Purifying Acetanilide by Recrystallization Purpose To be able to select an appropriate recrystallizing solvent, separate and purify acetanilide from a mixture by recrystallization, and compare the melting points of impure and recrystallized acetanilide. Procedure Part 1. Data Solvent Solubility @ 25˚C Solubility @ boiling point Water I S Ethanol S S Acetone S S Petroleum Ether I I Fig 1. The above data refers to the solubility (S) or insolubility (I) of acetanilide in deionized water, ethanol, acetone, and petroleum ether. The data was collected to determine which solvent would be best as a recrystallizing solvent for acetanilide. From this data we can determine that deionized water will work. Mass of empty container: Mass of container + “crude” acetanilide: Mass of “crude” acetanilide: Approximate volume of solvent used: Mass of empty container: Mass of container + purified acetanilide: Mass of purified acetanilide: Discussion Post Lab Questions
