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 synthetic porous crystalline material, MCM-56, is synthesized by a process comprising the steps of: a) preparing a reaction mixture containing sources of alkali or alkaline earth metal (M) cation, an oxide of an trivalent element X, an oxide of a tetravalent element Y containing at least 30 wt. % of solid YO.sub.2, a directing agent (R), and water, said reaction mixture having a composition, in terms of mole ratios of oxides, within the following ranges:

Process for preparing the synthetic porous crystalline material MCM-56

Relatively short chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively short chain alkylating agent under sufficient reaction conditions in the presence of a catalyst comprising zeolite MCM-56. The liquid phase syntheses of ethylbenzene and cumene are particular examples of such MCM-56 catalyzed reactions.

Process for preparing short chain alkyl aromatic compounds

This invention relates to use of synthetic layered material MCM-56 as a sorbent and as a catalyst component in catalytic conversion of organic compounds. Examples of sorbent use include rapid sorption of hydrocarbons and separating at least one hydrocarbon component from a mixture of hydrocarbon components having differential sorption characteristics with respect to MCM-56. Examples of catalytic use include acid catalyzed reactions, such as cracking, aromatic compound alkylation, and isoalkane alkylation.

MCM-56 as sorbent and catalyst component

Relatively short chain alkyl aromatic compounds are prepared by alkylating or transalkylating an alkylatable aromatic compound with a relatively short chain alkylating or transalkylating agent under sufficient reaction conditions in the presence of catalyst comprising zeolite MCM-49.

This invention relates to a new synthetic layered material, a method for its preparation and use thereof as a sorbent and as a catalyst component in catalytic conversion of organic compounds.

Synthetic layered MCM-56, its synthesis and use

This invention relates to a new synthetic porous crystalline material, a method for its preparation and use thereof in catalytic conversion of organic compounds. The new crystalline material exhibits a distinctive X-ray diffraction pattern.
