The present invention relates to a method for producing a cycloalkanol, and more particularly to a method for producing a cycloalkanol by catalytically hydrating a cycloalkene. Conventionally, methods for producing cycloalkanol by hydrating cycloalkenes include a method using sulfuric acid or phosphoric acid using a carrier, and a method using a cation exchange resin as a solid catalyst (Japanese Patent Publication No. 1973-
15619, Japanese Patent Publication No. 44-26656), or a method using heteropolyacids such as phosphotungstic acid and phosphomolybdic acid (Japanese Patent Publication No. 1089-1989)
etc. are known. However, these methods, such as the method of making ester using high concentration sulfuric acid and then hydrolyzing it, have problems such as recovery of sulfuric acid and removal of by-products, and problems with phosphoric acid and ion exchange resin have problems with catalyst life. be. Furthermore, in the case of heteropolyacids, the conversion rate is as low as several percent. By the way, there is an example of using an aromatic sulfonic acid for hydration of olefin. (Japanese Patent Publication No. 43-8104, Japanese Patent Publication No. 43-16125) However, with this method, the conversion rate is only a few percent.
It gave only a low result of 30%. Therefore, the present inventors conducted extensive studies to improve these problems, and as a result, they arrived at the present invention. That is, in the present invention, when catalytically hydrating a cycloalkene, aromatic sulfonic acid and silica gel or/
This is a method for producing a cycloalkanol, characterized by using a catalyst system comprising a metal compound of oxysulfuric acid and an oxysulfuric acid metal compound. According to the present invention, cycloalkanols are obtained at a higher conversion than using aromatic sulfonic acids alone,
The selectivity is also almost quantitative. Furthermore, even if a hydrocarbon compound such as benzene or cycloalkane is mixed, the reaction will not be adversely affected. In the present invention, as aromatic sulfonic acid,
p-toluenesulfonic acid, benzenesulfonic acid,
Aromatic monosulfonic acids such as anthraquinolsulfonic acid and polysulfonic acids are used. In the present invention, the silica gel used as a component of the catalyst may be any commercially available silica gel, and may be from a few meshes to several hundreds of meshes or granular ones. As for how to use it, you can use commercially available products as they are, but generally, for example, agate, etc.
It is better to use it after crushing it. Alternatively, it can also be used as a hydrogel produced from water glass. Further, as the metal oxysulfate compound, titanium oxysulfate, vanadium oxysulfate, etc. are used. These aromatic sulfonic acids and silica gel or/
and the metal oxysulfate compound can be mixed in any proportion. There is no particular restriction on the catalyst concentration in this reaction, but the higher the catalyst concentration in the aqueous solution, the more preferable it is, and the concentration used is usually at or above the saturation solubility of these catalysts at the reaction temperature. The amount of water used in the present invention is suitably in the range of 1 to 500 mol per 1 mol of cycloalkene. The reaction temperature ranges from 50 to 300℃, especially from 80 to
A range of 200°C is preferred. The reaction can be carried out under either normal pressure or increased pressure. Further, the reaction method can be carried out either in a batch method or a continuous method. EXAMPLES Next, Examples will be given to specifically explain the present invention, but the present invention is not limited to these Examples. Example 1

A reaction was carried out in the same manner as in Example 1 using only p-toluenesulfonic acid without using silica gel. The conversion rate of cyclohexene was 24.9%, and no products other than cyclohexanol were observed. Example 2 A reaction was carried out in the same manner as in Example 1, except that as the silica gel, commercially available water glass was treated with sulfuric acid to form a 20wt% hydrogel, which was used in the same amount as in Example 1 in terms of silica. The conversion rate of cyclohexene was teeth
Cyclohexene reacted at 31.5% to give cyclohexanol quantitatively. Examples 3 to 5 The catalyst was changed from silica gel to titanium oxysulfate, the amount of cyclohexene was changed, and the reaction was carried out at 110°C for 4 hours under the conditions shown in Table 2. The results are shown in Table 2.
