1. Separation and Purification of Organic Compounds
Get pure organic compounds
Methods Separation and Purification are:
1- solution and filtration.
2- Extraction
3- crystallization
4- Sublimation
5- Distillation
6- Chromatographic

2. Solution and filtration
Solubility of organic compounds can be divided:
1- solubility in which the chemical reaction such as acid-base reactions, used to identify the functional groups.
Benzoic acid NaOH sodium benzoate
(water insoluble) (water soluble)
2- solubility in which only simple miscibility such as ethyl ether in carbon CCl4, used to determine solvent in recrystallization
-Filtration used to separate the solid product(precipitate) ,remove of insoluble impurities, reactant materials
- The desired soluble comp. get from filtrate by evaporation the solvent
