3/16 Chem 322 Friday Partition Coefficient (Extraction) Lab for Benzoic Acid Reaction Mechanism: Purpose: The purpose of this particular lab was to demonstrate the difference in separation of Benzoic acid in water and Dichloromethane. Also the difference in separation of Benzoic acid in bicarbonate and Dichloromethane. By calculating the partition coefficient for each of these separations‚ it became clear the differences in the separation of the aqueous and organic layers. Observations

C. Central Composite Design As PBD considers only main effects and ignores the interactions among the factors‚ therefore‚ a new design is required. Central composite design (CCD) is type of experimental design‚ which was first described by Box and Wilson (1951). Nowadays it is widely used in response surface methodology (RSM; discussed in the next section of the review) for building a second order (quadratic) model for the response variable without using a complete three-level factorial experiment
