Rb. Borade et A. Clearfield, SYNTHESIS OF ZEOLITE-BETA FROM DENSE SYSTEM CONTAINING A MINIMUM OF TEMPLATE, Catalysis letters, 26(3-4), 1994, pp. 285-289
Zeolite Beta has been synthesized, in 24 h at 170-degrees-C, from an e
xtremely dense system in which the weight ratio of solid (sodium alumi
nate and SiO2) to liquid (tetraethylammonium hydroxide and H2O) mixtur
es is 1 : 1.8; the product has comparable catalytic properties to thos
e samples prepared by previous methods.
