Synthesis of large single crystals of templated Y faujasite

Large single crystals of zeolite Y with diameters up to 210–245 μm and Si/Al=1.71 have been synthesized from a reaction mixture (4.76Na 2O : 1.0Al 2O 3 : 3.5SiO 2 : 454H 2O : 0.6T 2O : 5TEA) comprising fumed silica (Cab-O-Sil M5), sodium aluminate, and the template bis(2-hydroxyethyl)dimethylammoniu...

Summary:Large single crystals of zeolite Y with diameters up to 210–245 μm and Si/Al=1.71 have been synthesized from a reaction mixture (4.76Na 2O : 1.0Al 2O 3 : 3.5SiO 2 : 454H 2O : 0.6T 2O : 5TEA) comprising fumed silica (Cab-O-Sil M5), sodium aluminate, and the template bis(2-hydroxyethyl)dimethylammonium chloride (TCl) in an aqueous triethanolamine (TEA) cosolvent.
