Recrystallization of Solid
Objective:
In process industries after solid handling operation the components are purified using recrystallization technique to remove of trace contaminants and the achieved produce will be >99% purity. Recrystallization is the important final stage unit operation in pharmaceutical industries for the production of active ingredients (bulk drugs) which are used to prepare final dosage form. The main objective of this experiment is to compute/analyse the final mass of acetanilide product from recrystallization. In this technique, the compound/molecule to be purified are dissolved in hot solvent using Erlenmeyer flask since it is easy to adapt for heating the mixture using steam bath and in addition helps to minimize the solvent loss by evaporation. Only Erlenmeyer flask needs to be used and no beaker is allowed since solvent evaporation during recrystallization process is not controllable in beaker result in impure crystallized product. The purity of product is based on the solvent used in recrystallization technique and the ideal solvent used will be nontoxic, inexpensive, inert to solute, solute dissolution at boiling point not low temperature (0-25 C), ability to dissolve impurities in total, not too volatile, low boiling point than solute melting point.
Once the targeted compound/molecule is in hot state should be filtered to achieve suspended state of dissolved...
