Abstract

The invention relates to the field of catalysts and provides a catalyst for synthesizing methyl isobutyl ketone and methyl isobutyl alcohol from acetone, and a preparation method and an application ofthe catalyst. The catalyst includes, on the basis of total weight being 100 parts, a) 0.5 to 5 parts of at least one of nickel or nickel oxides; b) 0.5 to 10 parts of at least one of cobalt or cobaltoxides; c) 82 to 99 parts of a supporter selected from at least one of silicon oxide, aluminum oxide, and zirconium oxide after high-temperature roasting titanium modification. The catalyst works under a gentle reaction condition and is higher in yield of the methyl isobutyl ketone than a palladium / resin catalyst that is applied commonly in industrial devices in the prior art. The catalyst also can be used for co-producing methyl isobutyl alcohol. The cost of the double-metal catalyst is significantly lower than that of the palladium catalyst in the prior art, so that the catalyst has excellent economic benefit.

Description

technical field [0001] The invention relates to the field of catalysts, in particular to a catalyst for preparing methyl isobutyl ketone and methyl isobutyl alcohol from acetone, a preparation method and application thereof. Background technique [0002] Methyl isobutyl ketone (MIBK for short) is an important solvent and chemical intermediate. It has attracted much attention because of its excellent performance. It has an aromatic ketone smell, is colorless and transparent, has a medium boiling point, and has a very strong solvency. , miscible with many organic solvents such as alcohol, benzene, ether, etc., can be used as paint, ethyl cellulose, nitrocellulose, audio and video tapes, paraffin, various natural or synthetic resin solvents, dewaxing agents, rare earth metal extractants, The raw materials of polymerization initiators, surfactants, pharmaceuticals, pesticide extractants and rubber antioxidants are currently relatively in short supply fine petrochemical intermedi...
