How is the silica gel column acidified?

Yes, in the wet upper column, add 2-3 drops of ice and acetic acid after mixing the silicate.

Silicone itself is acidic, why is it acidified?What structure are you?If it is decomposed in silica gel, it may not be suitable for column

Solid considers recrystallization.

Our common silica gel itself is acidic.If your things are broken down so fast, why do you still use silicone column?Try using a gap, recrystallization, and liquid, can also use a distillation, more, but don't know the nature of your product, or you have to explore it.
