Various methods have been proposed for producing a saturated higher ketone having a carbon skeleton, which is obtained by condensing two molecules of a lower ketone as a raw material. For example, the production method of methyl isobutyl ketone (hereinafter referred to as MIBK), which is a typical saturated higher ketone, is described by using acetone and hydrogen as raw materials,
A so-called three-step method via diacetone alcohol and mesityl oxide is used. However, this method has a long process and the raw material conversion rate is low because the first diacetone alcohol production process is an equilibrium reaction. Therefore, various studies have been made on a method for directly producing a saturated higher ketone from a lower ketone such as acetone and hydrogen in one step, and the following proposals have been made as catalysts.

Generally, a precipitation method as a method for preparing zirconium oxide,
Pyrolysis method, oxidation method and the like can be mentioned. For example, there is a method in which an alkali is allowed to act on an aqueous solution of a soluble salt such as chloride, oxychloride, or sulfate to cause precipitation, which is then baked and dehydrated at an appropriate temperature to obtain an oxide. However, the precipitate obtained by such a method contains Cl ~, S derived from the metal salt of the raw material,
In many cases, an anion such as O 4 2 or the like is contained, and according to the study by the present inventors, the presence or absence of these impurities is the surface acid-base strength of the obtained zirconium oxide, and sometimes the acid strength,
It was found that the activity of the catalyst for producing a saturated higher ketone from a lower ketone and the selectivity are decisively influenced. Therefore, in the present invention, when the precipitation method is used as the method for preparing the zirconium oxide, the obtained precipitate is sufficiently washed with water and, if necessary, treated with an acid or an alkali to remove impurities to obtain a surface acid-base strength. Must be substantially neutral.
Also, when other preparation methods are used, the surface acid-base strength of the resulting zirconium oxide must be made substantially neutral, for example, by using an extremely high-purity raw material.

Further, a catalyst component having a hydrogenation ability is required for producing a saturated higher ketone from a lower ketone according to the present invention. Generally, a platinum group element is used, but palladium is particularly effective and is used in the present invention. As a form of using palladium, there is a method of supporting it on the zirconium oxide, but a catalyst such as palladium-carbon or palladium-alumina may be mixed with the zirconium oxide and used. The amount of palladium used is usually 0.001 to 10% by weight, preferably 0.01 to 5% by weight, based on the zirconium oxide.

The reaction of the method of the present invention is carried out in the liquid phase. The reaction proceeds below the critical temperature of the lower ketone (235 ° C in the case of acetone), but at high temperatures, usually above 150 ° C, the selectivity for alcohols due to hydrogenation of the carbonyl group becomes high, and the desired saturated higher ketone There is a tendency that the yield of is slightly reduced. Further, since the catalytic activity cannot be obtained at a too low temperature, the reaction temperature is preferably in the range of 30 to 150 ° C. The reaction pressure is autogenous pressure or more lower ketones, usually 150 kg / cm 2 or less, preferably better between 1 to 50 kg / cm 2, is set in a hydrogen atmosphere. The catalyst may be used in the form of either a suspension bed or a fixed bed. It is preferable to control the conversion of the lower ketone to 50% or less.
