The dehydrogenation of n-parrofins to n-olefins is catalyzed by novel synthetic manganese oxide octahedral molecular sieves such as OMS-1 and OMS-2.

Dehydrogenation of N-paraffin to N-olefin employing manganese oxide

Manganese oxide octahedral molecular sieve (OMS) is produced by the method comprising:

Method of preparing manganese oxide octahedral molecular sieve

Synthetic manganese oxide octahedral molecular sieves, e.g., OMS-1 and OMS-2, are employed as acid-base catalysts in a variety of acid-base organic conversion reactions.

Manganese oxide octahedral molecular sieve as acid-base catalyst

Normal olefins such as n-butenes and normal alkanes such as n-butane can be coverted to branched olefin species such as isobutylene by skeletal dehydroisomerization over catalysts preferably containing metals selected from Groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, VIII and the rear earth elements which are deposited upon borosilicate zeolites having pore sizes of at least about 5 Angstroms and containing boron in the framework structure thereof. The borosilicates have sufficient acidity to catalyze the skeletal isomerization of both normal alkanes and normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.

A lower alkanol, such as methanol is oxycarbonylated with carbon monoxide and oxygen to yield e.g. dimethyl carbonate at 50.degree. C.-125.degree. C. and 300-1500 psig in the presence of as catalyst, a functionalized inorganic oxide substrate (such as silica gel) typically bearing on the surface thereof a ligand of ethyl formate and 3-aminopropyl triethoxy silane--which has been reacted with a metal salt such as CuCl.sub.2.

A method for preparing a catalyst composition is disclosed. In particular, a support is vacuum impregnated with at least one catalytically active element and, thereafter, the vacuum impregnated support is calcined to provide the catalyst composition. Preferably, the vacuum impregnation of the support is performed in a two-step sequence by (a) vacuum impregnating said support with said at least one element and, thereafter, calcining said support, and (b) vacuum impregnating said support with at least one other element. The catalyst composition prepared by the prescribed method is preferably used in a process for producing a mixture of lower aliphatic alcohols.

A novel catalyst system useful in preparation of dimethyl carbonate is prepared by complexing a metal salt such as cupric chloride CuCl.sub.2 with a ligand formed by reacting a carbonyl-containing organic compound such as ethyl formate with an organosilicon compound containing alkoxy and amine fucntionality, such as 3-aminopropyltriethoxysilane.

A novel ligand system useful in preparation of dimethyl carbonate is prepared by complexing a metal salt such as cuprous chloride Cu.sub.2 Cl.sub.2 with a ligand formed by reacting a carbonyl-containing compound such as ethyl formate with an organosilicon compound such as ethyl formate with an organosilicon compound containing alkoxy and amine functionality, such as 3-aminopropyltriethoxysilane or [3-(2-aminoethyl)aminopropyl]trimethoxysilane.

Unsaturated cyclic keto acids bearing pendant alkyl groups may be prepared by rearranging substituted dicarboxylic acid anhydrides in the presence of a strong Bronsted acid catalyst. The products may be useful as corrosion inhibitors in alcohol fuels and as intermediates in chemical and additive manufacture.
