- Abstract:
- Due to the production needs of the chemical plant of the chemical engineering department of our hospital, we hope to try to wash the crude chloroform containing a small amount of ethanol, so as to obtain industrial chloroform, and then provide production use: To this end, we must first obtain the liquid phase equilibrium relationship of this ternary system, and then further use the characteristics of low boiling point azeotrope to purify.Considering that the volume measurement is more convenient than the weight measurement in the industrial liquid material measurement, the volume percentage relationship is adopted in the experiment and the phase diagram is drawn.By referring to the weight composition of azeotrope, the volume percentage composition of azeotrope is also sought. Finally, the measure of how to extract and wash to obtain industrial chloroform is proposed by using the obtained phase diagram.
