There is provided a process for using amphiphilic compounds in preparing new classes of crystalline oxide materials. These oxide materials may have uniformly large pores, e.g., having a size of about 40 Angstoms in diameter. This process involves combining sources of oxides with micellar solutions of organic amphiphilic compounds, such as quaternary ammonium cationic surfactants. Aggregates of these micelles in the form of liquid crystals are believed to function as templates for the formation of the present highly porous, crystalline materials.

This invention relates to a method for modifying a synthetic composition of ultra-large pore crystalline material, e.g., silicate, comprising an inorganic, porous, non-layered crystalline phase material exhibiting, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than 18 Angstrom Units and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 6.7 kPa (50 torr) and 25.degree. C., by contacting with a treatment composition comprising an inorganic oxide of a trivalent element X, e.g., sodium aluminate, or precursor of said inorganic oxide, under sufficient conditions so that the trivalent element X is incorporated in the crystalline phase material. The composition is suited to use for catalytic conversion of organic compounds or as a sorbent.

There is provided a sulfated layered titanium oxide catalyst. Relatively long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively long chain alkylating agent under alkylation reaction conditions in the presence of this sulfated layered material as alkylation catalyst. The layered material contains titanium oxide in the layers and oxide pillars separating the layers. The alkylation activity of the catalyst is increased by including sulfate ions in the layered material. This increased alkylation activity may be obtained by contacting the layered material with an aqueous solution of a sulfate compound such as sulfuric acid.
