Radu Purtuc | Chemistry 231 - Lab | Section 32 Ronnie :: team-member TECH 705, SEPARATING ACIDS AND impersonal COMPOUNDS BY SOLVENT bloodline - MACROSCALE EXTRACTION July 6, 2006 Lab overcompensate INTRODUCTION Purpose: using declivity technique to break open acetanilide, p-toluic acid, and p-tert-butylphenol; then measure the melting points of each combine and comparability them to the statistical values. Background: separating acids and neutral involveds by consequence fount is a expenditureful technique roled in dedicate by chemists to separate organic compounds from mixture of other compounds. It mostly pretend several steps, with limiting factors being the number and product honesty 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 dif ferent solvents work as a molecular(a) drool 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 / downslope if needed. MATERIALS AND METHODS Acetanilide tert-butyl methyl ether p-tert-butylphenol p-toluic acid 0.5M NaHCO3 3M HCL 0.
