Pervaporation of Volatile Amine Solutions Using Polysulfone-C_(60) Nanocomposite Membranes

摘要

The development and implementation of new technologies for separation processes represents one of the great challenges of membranology. The pervaporation of the aromatic amine solutions presents particular importance, with applications especially in the pharmaceutical, dyes industry and environment protection upon the purification and separation of the residue resulted from the synthesis of aromatic intermediates. The synthesis of new polysulfone - C_(60) fullerene membranes used for the pervaporation of the aromatic amine solutions is presented in this paper. The synthesized materials were characterized by FT-IR spectroscopy, TGA-DTA thermal analysis and SEM microscopy. For the aniline pervaporation tests, the obtained membranes were used, as well as a polysulfone membrane obtained from chloroform without fullerene. Best results were obtained for the polysulfone membrane with fullerenes obtained from chloroform.
