The invention relates to a process of producing a carbonyl compound by dehydrogenating a linear aliphatic alcohol of 1 to 6 carbon atoms in the gas phase in the presence of a solid catalyst comprising a ruthenium catalyst supported on a carrier such as zinc oxide or magnesium oxide.

Process for producing carbonyl compounds

1-Butene and isobutene are effectively separated without isomerization of 1-butene by contacting an isobutene-containing hydrocarbon mixture with a solid acid catalyst having a solid acid quantity of 0.05 to 0.25 mmol/g of solid acid catalyst, represented by the adsorption quantity of pyridine, thus low-polymerizing selectively isobutene and then separating the low polymers of isobutene from 1-butene.

Process for the low polymerization of isobutene

1-Butane and isobutene are effectively separated without isomerization of 1-butene by contacting an isobutene-containing hydrocarbon mixture with a solid acid catalyst having a solid acid quantity of 0.05 to 0.25 mmol/g of solid acid catalyst, represented by the adsorption quantity of pyridine, thus low-polymerizing selectively isobutene and then separating the low polymers of isobutene from 1-butene.
