Purifying crystallisation
Cards in this deck (5)
- 1Step 1Filter the precipitate under reduced pressure
- 2Step 2Dissolve the solid in the minimum volume of solvent needed which dissolves in hot water
- 3Step 3Quickly filter the mixture to remove impurities which do not dissolve in hot solution and then place the solution in ice cold water so the derivative re crystallises
- 4Step 4Filter the solution under reduced with pressure and wash with cold solvent
- 5Step 5Leave crystals to dry
