Impurity separation
WitrynaFrom this result, a generic method for full separation of the impurity and sartans could not be achieved indicating further method development was needed. Given the … WitrynaGood separation requires sufficient time to obtain an equilibrium condition between the two liquid phases at the temperature and pressure of separation. ... and the impurities are removed from the main product by distillation. An extra separation unit might be required depending on the amount of the unreacted IBAP in the mixture.
