There have been determined optimimum parameters of the process and compositions of the material flows have been identified. A new system for pentaerythritol isolation has been developed involving cycling/looping of the material flows, ion-exchange purification and obtaining pentaerythritol of two grades. Five new design types of the main equipment have been developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
