摘要: Highly siliceous crystalline zeolitic molecular sieve compositions, having pore diameters of approximately 6 Angstroms, are prepared hydrothermally from reaction mixtures free of organic cations. These novel zeolites can be distinguished from all other zeolites on the basis of certain infrared spectral characteristics and have hydrophobic/organophilic properties which permit their use in selectively adsorbing organic materials from water, either in liquid or in vapor phase.

摘要: A novel zeolitic molecular sieve composition denominated Upsilon is synthesized from aqueous gels in the Na.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 system. The molecular sieve has a pore diameter of about 3.5 Angstroms, a characteristic x-ray diffraction pattern and a composition expressed in moles of oxides as:Na.sub.2 O.Al.sub.2 O.sub.3.2.4-3.4 SiO.sub.2.O-4.5 H.sub.2 O

摘要: A novel synthetic crystalline zeolite denominated zeolite "Phi" is prepared hydrothermally from aqueous gels in the [N(CH.sub.3).sub.4 ].sub.2 O - Na.sub.2 O - Al.sub.2 O.sub.3 - SiO.sub.2 system. As synthesized, the zeolite exhibits large-pore adsorption characteristics, a characteristic X-ray powder diffraction pattern and a composition expressed in moles of oxides as: 0.95-1.05 Na.sub.2 0:0.02-0.05 {N(CH.sub.3).sub.4 }.sub.2 O:Al.sub.2 O.sub.3 :4-7 SiO.sub.2 :O-6 H.sub.2 O.
