Synthesis of N-Formylation of Amines using Various Ion Exchanged Forms of Zeolite-A as Catalysts
Formamides represent an important class of intermediates in various organic syntheses. They have been used in the synthesis of some pharmaceutically important compounds such as Fluoroquinolones [1], 1, 2 dihydro quinolones [2] and Nitrogen based heterocyclic compounds [3]. In Lewis bases, its main importance is to catalyze some important reactions such as allylation [4] and hydrosilyation of ca...
متن کاملThe mechanism of dimethyl carbonate synthesis on Cu-exchanged zeolite Y
The mechanism of dimethyl carbonate (DMC) synthesis from oxidative carbonylation of methanol over Cu-exchanged Y zeolite has been investigated using in situ infrared spectroscopy and mass spectrometry under transient-response conditions. The formation of DMC is initiated by reaction of molecularly adsorbed methanol with oxygen to form either monoor di-methoxide species bound to Cu+ cations. Rea...

15 صفحه اولNovel Synthesis Method of Micronized Ti-Zeolite Na-A and Cytotoxic Activity of Its Silver Exchanged Form
The core-shell method is used as a novel synthetic process of micronized Ti-Zeolite Na-A which involves calcination at 700°C of coated Egyptian Kaolin with titanium tetrachloride in acidic medium as the first step. The produced Ti-coated metakaolinite is subjected to microwave irradiation at low temperature of 80°C for 2 h. The prepared micronized Ti-containing Zeolites-A (Ti-Z-A) is characteri...
متن کاملSelective Production of Aromatics from 2-Octanol on Zinc Ion-Exchanged MFI Zeolite Catalysts
The aromatization of 2-octanol derived from castor oil as a byproduct in the formation of sebacic acid was investigated on various zeolite catalysts. Zn ion-exchanged MFI (ZSM-5) zeolites with small silica/alumina ratios and zinc contents of 0.5 to 2.0 wt. % were determined to exhibit good and stable activity for the reaction at 623 to 823 K. The yield of aromatics was 62% at 773 K and the spac...
