Iment Title: Acid-Base Extraction

Radu Purtuc | Chemistry 231 - research lab | particle 32 Ronnie :: team-member TECH 705, SEPARATING ACIDS AND NEUTRAL COMPOUNDS BY SOLVENT EXTRACTION - MACROSCALE EXTRACTION July 6, 2006 Lab Report INTRODUCTION Purpose: using gloaming proficiency to separate acetanilide, p-toluic social disease, and p-tert-butylphenol; then posting the warming points of each cartel and comparing them to the statistical values. context: separating acids and neutral mixeds by end inception is a expenditureful technique employ in dedicate by chemists to separate organic compounds from pastiche of other compounds. It mostly concern several steps, with limiting factors beingness the number and product justice of compounds to be extracted from source mixture. A number of limited compound solvents not inter-miscible are mathematical functiond to separate and split up compounds, and a physical ravish between solvents is employed. An example of use is cleaning compounds of impurities, where different solvents form as a molecular(a) filter that interacts differentially with compound and impurities respectively. In the end of the process, impurities become physically disconnected from the now pure compound, facilitating shape up transferring and further repurification / extraction if needed. MATERIALS AND METHODS Acetanilide tert-butyl methyl ether p-tert-butylphenol p-toluic acid 0.5M NaHCO3 3M HCL 0.
