Abstract: A catalyst is disclosed comprising a thin outer shell of catalytic material bonded to an inner core of catalytically inert material. The catalyst is made by coating a catalytically inert core such as alpha alumina, with a thin layer of finely divided catalytically active material in a slurry of colloidal boehmite/pseudo boehmite then calcining to convert the boehmite/pseudo boehmite into .gamma. alumina thereby bonding it to the inert core. Catalysts made by this technique containing an outer shell of platinum on fluorided alumina in an inert core of alpha alumina .gamma. are attractive isomerization catalysts.

Abstract: A process is disclosed for pillaring layered materials which do not swell appreciably in water. The process comprises first intercalating an amine or other neutral molecule such as an amide or dimethyl sulfoxide between the layers of the material to be pillared. This allows the subsequent incorporation of inorganic pillars which are more temperature stable than the intercalated amine. Also, disclosed are different pillared products produced by the process. The starting materials do not appreciably swell in water and the pillared composition final product is produced by swelling with an inorganic intercalate and then displacing the inorganic intercalate with an inorganic pillaring substance.

Abstract: Novel chromium-containing compounds, such as, for example, chromium pyrrolides, are prepared by forming a mixture of a chromium salt, a metal amide, and an electron pair donor solvent, such as, for example, an ether. These novel chromium-containing, or chromium pyrrolide, compounds can be used either unsupported or supported on an inorganic oxide support to trimerize and/or polymerize olefins.

Abstract: A seam cleaning paste, cream or liquid is disclosed, which comprises a hydrocarbon solvent and a finely divided inorganic powder. Treatment of the area near the seams of various types of floor coverings, especially highly stain resistant and soil resistant floor coverings, does not significantly change the appearance of the floor nor its resistance to soiling or staining. Yet it results in much improved adhesion of certain seam coaters subsequently applied to bridge the seam and prevent dirt from lodging therein. These creams do not exaggerate bubble formation in subsequently applied seam coaters and in fact, preferred embodiments help prevent such bubbles from forming.

The second component comprises a cation which will irreversibly react with at least one ligand on the Group IV-B metal complex and a non-coordinating anion. The combination of the two components produces an ionic catalyst composition comprising a cationic bis(cyclopentadienyl) Group IV-B metal complex which has a formal coordination number of 3 and a 4+ valence charge and the aforementioned non-coordinating anion.
