Which method must i use for recrystallization? ( to purify/clean acid residue better )
using 2.5 ml acetone for each 1 gram petn ( pentaerythritol tetranitrate )
First Acetone and sodium bicarbonate had heated to 50 C.
Then petn ( pentaerythritol tetranitrate ) was added gradually to this mixture.
2-3 minutes later after petn ( pentaerythritol tetranitrate ) was dissolved entirely, mixture is pured to cold water.
at this stage ( this step ) which percent of sodium bicarbonate (gram) must i put into / (add to) acetone?
This method is correct??? İs there anything wrong? Is there anything I should add?
