Abstract: | The techiniques of normal freezing, zone melting and column crystallization are discussed ; special attention is given to micro zone melting. The preparation of absolutely pure benzene by column crystallization is shown to be possible. Many examples of the utilization of these techniques are given, including work on isomeric compounds, plant and animal products and meteorite samples. |
