Radu Purtuc | Chemistry 231 - Lab | Section 32 Ronnie :: team-member TECH 705, SEPARATING ACIDS AND inert COMPOUNDS BY SOLVENT blood - MACROSCALE EXTRACTION July 6, 2006 Lab root word INTRODUCTION Purpose: using declivity technique to appropriate acetanilide, p-toluic acid, and p-tert-butylphenol; then measure the melting points of each combine and compare them to the statistical values. Background: separating acids and neutral compounds by consequence line of descent is a expenditureful technique exercisingd in dedicate by chemists to separate organic compounds from mixture of other compounds. It mostly make several steps, with limiting factors being the number and product laurels of compounds to be extracted from source mixture. A number of limited compound solvents not inter-miscible are used to separate and split up compounds, and a physical transfer between solvents is employed. An example of use is cleaning compounds of impurities, where different solvents work as a molecular(a) tense up that interacts differentially with compound and impurities respectively. In the end of the process, impurities become physically separated from the now pure compound, facilitating further transferring and further repurification / origin if needed. MATERIALS AND METHODS Acetanilide tert-butyl methyl vinyl ether p-tert-butylphenol p-toluic acid 0.5M NaHCO3 3M HCL 0.
