In experiment 2, the procedure is as follows: The column is filled with hexane and then alumina is added The mixture is dissolved in toluene, and the solution is then pipetted on the top of the column The compounds are eluted with 4:1 hexane/dichloromethane, then 4:1 hexane/ethyl acetate from fraction 4 onwards.
