A silica-sodalite was obtained from ehtanolamine and ethylenediamine-glycerol media. The syntheses of silica-zeolites in various nonaq. media was studied and silica-ZSM-39 and a phase K with unknown structure were obtained. The crystalline products were characterized using x-ray diffraction, IR, chem. composition anal., and DTA-TG. Elec. conductivity measurement and determination of the concentration of silicates in solution were used to study the nature of nonaq. solution and the prerequisites for the formation of silica-zeolites in nonaq. media.
