Optimization of synthetic conditions of MFI in fluorine alkaline medium
Written by sctunisie no commentsA synthesis route of MFI type zeolites consist a in replacing the usually mineralizer OH- anions by F- anions. This allows crystallization in wide range of pH (alkaline and non alkaline media). In alkaline fluoride media at pH 10-12, the synthesis was carried out under mild operating conditions (T=90-100°C) during 5 days. In view of this, we have performed a series of experiments in order to obtain the optimal composition of gel mixture, which leads to pure phase, without any undesired impurity. The as- synthesized samples were characterized with various techniques (XRD, IR, MEB).
