This invention relates to a new synthetic porous crystalline material, designated MCM-71, a method for its preparation and its use in catalytic conversion of organic compounds. The new crystalline material exhibits a distinctive X-ray diffraction pattern and has a unique 3-dimensional channel system comprising generally straight, highly elliptical channels, each of which is defined by 10-membered rings of tetrahedrally coordinated atoms, intersecting with sinusoidal channels, each of which is de...

This invention provides a process for the synthesis of MCM-58 using 1-(1-adamantyl)pyridinium cations as a directing agent. The resultant MCM-58 is useful in a variety of hydrocarbon conversion reactions including toluene disproportionation, transalkylation of aromatics, reaction of paraffins with aromatics, paraffin isomerization and alkylation of aromatics with olefins.

The quaternary Zintl material (Et.sub.4 N).sub.4 [Au(Ag.sub.1-x Au.sub.x).sub.2 Sn.sub.2 Te.sub.9 ] that contains 1-D semiconducting chains composed of four metallic elements is prepared by treating ethylenediamine extracts of a pentanary K--Au--Ag--Sn--Te alloy with Et.sub.4 NI.

This invention relates to a new synthetic porous crystalline material, designated MCM-70, having, in its calcined form, the x-ray diffraction pattern of Table 1 above. The invention further resides in a method for preparing MCM-70 in borosilicate and in the conversion of organic compounds contacted with an active form of MCM-70.

This invention relates to a new synthetic porous crystalline material, designated MCM-67, a method for its preparation and use thereof in catalytic conversion of organic compounds. MCM-67 appears to be closely related in structure to VPI-8 and SSZ-41 but is synthesized without zinc and in the presence of manganese and/or cobalt ions.

Incorporation of zirconium, nickel and/or copper into M41S results in selective sorption of bulky organic molecules. Zirconium, nickel and/or copper may be incorporated into M41S by exchange or impregnation.

This invention relates to a novel synthetic porous crystalline molecular sieve material, MCM-65, to a reaction mixture and method for its preparation, and to use of the MCM-65 in catalytic conversion of organic compounds. The crystalline material exhibits a distinctive X-ray diffraction pattern as shown in Table 1.

A new synthetic porous crystalline material, designated EMM-1, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making EMM-1 in the presence of HF using various organic nitrogen compounds as directing agents. Aluminum-containing EMM-1 can be produced either by inclusion of Al in the synthesis, or by incorporation of B or Ga in the synthesis, followed by post treatment with aluminum nitrate or other sources of Al. EMM-1 is us...
