摘要:Synthesis and use of a new class of polymeric materials with favorable separation characteristics for the dehydration of ethanol and other organic solvents is described herein. The thermally rearranged (TR) polybenzoxazole (PBO), polybenzimidazole (PBI) and polybenzothiazole (PBT) membranes of the present invention can be used for the dehydration of ethanol during processing to fuel grade biodiesel by either pervaporation or vapor permeation. The unique microstructure of the membranes provides excellent separation characteristics, and this, coupled with their inherent thermal and chemical stability, enables their usage in other separations, such as the dehydration of other organic solvents.
