Chromatographic Separation of Benzyl Alcohol and Methyl Benzoate

Discovery Experiment Column Chromatographic Separation of Benzyl Alcohol and Methyl Benzoate 

Design and execute an experimental procedure for separating benzyl alcohol (7) from methyl benzoate (8) by normal-phase column chromatography. 

Place recovered petroleum ether in the container for nonhalogenated organic liquids, but pour the recovered dichloromethane into a container for halogenated organic liquids. Spread out the alumina adsorbent, which is wet with organic solvent, in a hood to dry and then place it in the nonhazardous solid waste container. 

What are two important characteristics of the silica gel and alumina that are used for column chromatography  

Explain why it is unwise to use column chromatography on compoimds having boiling points below about 150 C (760 torr).
