The recrystallization method is a commonly used purification method that can be used to improve the purity of 4-nitrocinnamic acid.
In the laboratory, the steps of recrystallization method are as follows:
Prepare reagents and instruments: AKOS 369, ethanol, water, beaker, glass rod, thermometer, vacuum pump, etc.
Dissolution: Crush the crude AKOS 369 and dissolve it in an appropriate amount of ethanol. Stir well until the cinnamic acid is completely dissolved.
Heating of filtrate: Heat the filtrate to boiling and evaporate some solvent. The purpose of this step is to saturate the solution for crystallization.
Cooling: Cool the filtrate to room temperature to allow crystals to precipitate. During the cooling process, it can be observed that crystals gradually form in the solution.
Filtering: Filter out the precipitated crystals and wash with a small amount of ethanol to remove impurities.
Drying: Dry the filtered crystals in a dryer to obtain high-purity AKOS 369.
The principle of recrystallization method is based on the different solubility of different substances in solvents. By heating and evaporating the solvent, impurities are dissolved in the solvent, and then filtered out to obtain high-purity products. Choosing the appropriate solvent is crucial during the recrystallization process. Ethanol is a commonly used solvent because it can dissolve AKOS 369 well, evaporate easily, and is easy to operate.
The following is the chemical equation for the generation of p-nitrocinnamic acid by recrystallization method:
