Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.

Disclosed is a process for the preparation of a 2,2,4,4-tetraalkylcyclobutane-1,3-diols by hydrogenation of a 2,2,4,4-tetraalkylcyclobutane-1,3-dione in the presence of a catalyst comprising ruthenium deposited on a carbon nanotube support. The process is useful for the preparation of 2,2,4,4-tetramethylcyclobutane-1,3-diol. The process may be carried out in the presence or absence of a solvent and in the liquid or vapor phase. Also disclosed is a process for modifying the cis:trans ratio of the 2,2,4,4-tetramethylcyclobutane-1,3-diol hydrogenation product by contacting the diol with hydrogen in the presence of a supported ruthenium catalyst.

A method of iodinating hydroxyaromatic and aminoaromatic compounds is disclosed, comprising reacting the hydroxyaromatic or aminoaromatic compound with an aqueous solution of a metal iodide and a metal hypochlorite at a temperature about -100.degree. to 100.degree. C. in the presence of an alcohol having 1-10 carbon atoms.

Disclosed is a process for the recovery of the iodine and alkyl value of an alkyl iodide by a process comprising (I) carbonylating an alkyl iodide by a process presence of a carbonylation catalyst, carbon monoxide and a hydrogen donor to obtain a mixture of hydrogen iodide and an acyl compound and (II) oxidizing the hydrogen iodide of step (I) to elemental iodine.

Process for the recovery of elemental iodine from alkyl iodides

Disclosed is a process for dehydrohalogenating an aromatic bromide or iodide by contacting the aromatic halide with hydrogen at elevated pressure in the presence of an alkyl halide-forming compound and a Group VIII metal catalyst. The presence of the alkyl halide-forming compound, such as an alkanol, diol, triol or derivative thereof, facilitates the dehydrohalogenation reaction and permits the recovery of the halogen ad alkyl halides from which the bromide and iodide values can be economically recovered.
