Abstract: Catalyzed vapor-phase processes are taught for the oxidative dehydrogenation of a lower-alkyl-monosubstituted ethylbenzene to a lower-alkyl-monosubstituted styrene. Barium pyrophosphate and the pyrophosphate-containing calcination product of KFe.sub.3 H.sub.14 (PO.sub.4).sub.8.nH.sub.2 O, n running between about 1 to about 4, are shown to effectively catalyze these dehydrogenations at a low enough temperature such that very little cracking of the lower alkyl group occurs which gives superior conversions and selectivities to the corresponding styrenes and lengthened catalyst lifetime. An improved method of preparation of KFe.sub.3 H.sub.14 (PO.sub.4).nH.sub.2 O is described as well as the new material which is essentially KFe.sub.3 H.sub.6 (P.sub.2 O.sub.7).sub.4.

Abstract: A catalyst or catalyst component for the polymerization of copolymerization of alpha-olefins, which is formed by a process comprising forming a solution of a magnesium-containing species in a liquid comprising at least one alcohol.

Abstract: Magnesium-aluminum, hydrotalcite-type clay compositions containing large, pillaring organic, inorganic, and mixed organic/inorganic anions have been made. Heating of the mixed large organic/inorganic anion hydrotalcite-type clays can lead to substantially complete removal of the organic anions and a route to making large, inorganic-anion, hydrotalcite-type clays with more open galleries. These materials are shown to catalyze hydrocarbon conversion reactions.
