    dependent on the chemical and physical properties of the core material. There are many factors that affect the efficiency of encapsulation. This includes‚ solubility of polymer in solvent‚ solubility of organic solvent in water‚ concentration of polymer‚ ratio of dispersed phase to continuous phase‚ interaction between core material and polymer and solubility of core material in the continuous phase. Microencapsulation can be applied in industry‚ through the release of core material. The four main

    Recrystallization of Benzoic acid Chemistry 204-002 Date: 4/9/2011 Hector Ortega Recrystallization is a method used to purify compounds‚ and this is a very important procedure because compounds are naturally impure. Polarity and solubility play a big role in this experiment and these characteristics are exploited in order to have a crystallization of the desired compound. In this experimented benzoic acid was crystallize using ethanol and water. I chose these solvents based on part C of the experiment

    standing D ef n i itions SOLUBILITY - It is the number of parts of solvent (by volume) that will dissolve one part of solute (by weight of a solid or liquid). - It also can be defined as the amount of a solute that passes into solution - A solute will dissolve best in a solvent that has a similar polarity to itself. MISCIBILITY when the two components forming a solution are either both gases‚ solids or liquids it is more usual to talk in terms of miscibility rather than solubility. Solutions Solvent:

    for 9-fluorenone did not show any significant bonds except for at 1681 cm-1‚ the C=O stretch. To separate 4-aminobenzoate into an aqueous layer‚ HCl was added to protonate the NH2 side group and form a salt‚ creating its high solubility in water and low solubility in ether.  This allowed the immiscible layers to be distinguished. The addition of NaOH after pouring out the aqueous solution allowed for aminobenzoate to reform from its salt form. However‚ while inverting the funnel to vent before

    ------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed
