To recover the unknown solid, the dichloromethane will be evaporated under reduced pressure, using a rotovap (short for rotary evaporator). The rotovap works under reduced pressure (partial vacuum) which reduces the boiling point of the solvent. This allows the dichloromethane to boil off at room temperature. The importance of
