This invention relates to a new synthetic crystalline material comprising acidic surface silanol groups, designated MCM-69, a method for its preparation and use thereof in catalytic conversion of organic compounds.

Synthetic crystalline MCM-69, its synthesis and use

The present invention is directed to a large-pore aluminosilicate molecular sieve comprising alumina and silica, where the ratio of SiO,/Al,O,ranges from about 75 to 600, and its method of preparation. The large-pore aluminosilicate molecular sieve of the present invention has the ability to catalyze reactions involving particularly bulky transition states or large molecules.

Aluminosilicate molecular sieve

High activity ZSM-5 and ZSM-11, with alpha values of 1000 to 3500, are produced by synthesis from a reaction mixture containing an organic directing agent selected from a non-cyclic amine having the formula (C,H,N),N,H,wherein n is 1, 2 or 3; m is 0 or 1; q is 0, 1 or 2 and (n&plus;m&plus;q) is either 2 or 4.

Synthesis of ZSM-5 and ZSM-11

The present invention relates to a composition and a method for preparing ZSM-48 exhibiting an X-ray pattern having values as set forth in Table 1 of the specification. The method of the present invention includes (a) preparing a reaction mixture; and (b) maintaining the mixture under crystallization conditions until crystals of the ZSM-48 are formed. The mixture includes a source of silica, a source of trivalent metal oxide, an alkali metal oxide, ethylenediamine and water. The mixture, in terms of mole ratios of oxides, has the following composition ranges:

Synthesis ZSM-48

A material exhibiting third order nonlinear optic properties includes quantum size clusters of semiconducting guest material incorporated into the pores of M41S material in an arrangement to provide nonlinear optic properties. A material exhibiting second order nonlinear optic properties includes an organic guest material incorporated into the pores of M41S material so that a non-centrosymmetric structure is formed which will provide second harmonic generation when subjected to electromagnetic radiation of a selected frequency.

M41S materials having nonlinear optical properties

The invention provides a method for synthesizing a porous inorganic solid comprising the steps of: (a) forming a reaction mixture containing water, an alumina source, a silica source, an alkali metal oxide source, and a diquaternary ammonium salt having the formula: ##STR1## wherein R is a diamondoid group, n is from about 1 to about 50, and X is an anion which is not detrimental to the formation of said porous inorganic solid; and

Method for synthesizing microporous crystalline material

This invention relates to a new crystalline composition MCM-40, to a method for synthesizing said crystalline composition using diaminocyclohexane as a directing agent and to use of said crystalline composition as a catalyst component for organic compound, e.g. hydrocarbon compound, conversion.

Crystalline (metallo) aluminophosphate composition MCM-40, its synthesis

This invention relates to an efficient process for shape-selective conversion of organic feedstock with a catalyst comprising a Clathrate Group tectosilicate such as ZSM-39 and a highly siliceous, shape selective zeolite such as ZSM-5. In one embodiment, a stabilized, dewaxed lube stock is prepared by catalytically dewaxing a hydrocrackate.
