These second metal components may be supported alone or in combination of two or more.
次に当該触媒の調製方法の一例について説明する。
まず、イオン交換水などの媒体に、前記の多孔性酸化物などの担体を加えて懸濁させたのち、この懸濁液に、（A）’ルテニウム化合物及び（Ｂ）’第二金属成分源である金属化合物をイオン交換水などの媒体に溶解させた溶液を加え、攪拌しながら必要に応じて加熱し、２０〜９５℃程度、好ましくは４０〜８０℃の温度に調節する。
前記（A）’ルテニウム化合物としては、例えばルテニウムの塩化物、硝酸塩、蟻酸塩、アンモニウム塩等が挙げられ、（Ｂ）’第二金属成分源である金属化合物としては、例えば塩化物、硝酸塩、炭酸塩、硫酸塩、アンモニウム塩等が挙げられる。
Next, an example of a method for preparing the catalyst will be described.
First, a carrier such as the porous oxide is added and suspended in a medium such as ion-exchanged water, and then (A) 'ruthenium compound and (B)' second metal component source is added to this suspension. A solution in which a metal compound is dissolved in a medium such as ion-exchanged water is added, heated as necessary while stirring, and adjusted to a temperature of about 20 to 95 ° C, preferably 40 to 80 ° C.
Examples of the (A) ′ ruthenium compound include ruthenium chloride, nitrate, formate, and ammonium salt, and (B) ′ a metal compound as the second metal component source includes, for example, chloride, nitrate, Examples thereof include carbonates, sulfates and ammonium salts.
次いで、（A）’ルテニウム化合物及び（Ｂ）’第二金属成分源である金属化合物を含む懸濁液にアルカリを加えてｐＨを４〜１２、好ましくは６〜１１程度に調整して加水分解させ、熟成することによって、ルテニウム成分及び第二金属成分を多孔性酸化物などの担体に担持させる。前記アルカリについてはその種類は特に制限はないが、アンモニア水、ナトリウム、カリウムなどのアルカリ金属の炭酸塩、水酸化物等が使用できる。ｐＨを調整して熟成する時間については、（A）’ルテニウム化合物及び（Ｂ）’第二金属成分源である金属化合物が加水分解する時間を確保出来れば良く、特に制限されない。 Next, (A) 'ruthenium compound and (B)' hydrolyze by adding alkali to the suspension containing the metal compound as the second metal component source and adjusting the pH to about 4 to 12, preferably about 6 to 11. The ruthenium component and the second metal component are supported on a support such as a porous oxide by aging. The type of the alkali is not particularly limited, but alkali metal carbonates such as ammonia water, sodium and potassium, hydroxides, and the like can be used. The time for ripening by adjusting the pH is not particularly limited as long as the time for hydrolysis of the metal compound (A) ′ ruthenium compound and (B) ′ second metal component source can be secured.
次に、例えばホルムアルデヒド、ヒドラジン、水素化ホウ素ナトリウム等の還元剤を加え、必要に応じて加熱し、２０〜９５℃程度、好ましくは６０〜９５℃の温度で還元処理した後、ろ過などにより固液分離し、得られた固形物を、充分に水洗後、好ましくは１４０℃以下の温度で常圧又は減圧下で乾燥処理する。前記還元剤は１種を単独で用いてもよく、２種以上を組み合わせて用いてもよい。
この還元剤は、担持されたルテニウム成分及び第二金属成分を効果的に還元するために金属全量に対して、通常１〜５０倍モル程度、好ましくは１５〜４０倍モルの割合で用いられる。
Next, for example, a reducing agent such as formaldehyde, hydrazine, sodium borohydride and the like is added, heated as necessary, reduced at a temperature of about 20 to 95 ° C., preferably 60 to 95 ° C., and then solidified by filtration or the like. The solid obtained after liquid separation is sufficiently washed with water, and then dried at a temperature of 140 ° C. or lower under normal pressure or reduced pressure. The said reducing agent may be used individually by 1 type, and may be used in combination of 2 or more type.
In order to effectively reduce the supported ruthenium component and the second metal component, this reducing agent is usually used at a ratio of about 1 to 50 times mol, preferably 15 to 40 times mol for the total amount of metal.
上記還元処理の時間は、還元反応が所望する程度に進行する時間が確保出来れば良く、特に制限されない。
なお、前記還元処理の操作は、必ずしも必要ではなく、ルテニウム成分を加水分解で担持させた後、固液分離し、得られた固形物を充分に水洗して乾燥処理しても良い。
The time for the reduction treatment is not particularly limited as long as the time for the reduction reaction to proceed to a desired level can be secured.
The operation of the reduction treatment is not always necessary, and after the ruthenium component is supported by hydrolysis, it may be subjected to solid-liquid separation, and the obtained solid matter may be sufficiently washed with water and dried.
本発明においては、担体へのルテニウム成分及び第二金属成分の担持を、前記のように加水分解にて行うことから、通常含浸法等において行われる高温での焼成処理、不活性ガス雰囲気下での高温還元処理等の操作を必ずしも必要とせず、触媒の調製が簡易である。
このようにして得られたルテニウム系触媒は、十分な触媒活性や選択性及び経済性などの観点から、ルテニウム成分を、担体を含めた触媒全量に基づき、ルテニウム金属として好ましくは０．１〜２５質量％程度、更に好ましくは１〜１５質量％の割合で含有する。また、第二金属成分を、担体を含めた触媒全量に基づき、金属として好ましくは０．１〜２５質量％程度、更に好ましくは０．２〜１５質量％の割合で含有する。
In the present invention, since the loading of the ruthenium component and the second metal component on the support is performed by hydrolysis as described above, the firing process at a high temperature usually performed in an impregnation method or the like, under an inert gas atmosphere Thus, an operation such as a high-temperature reduction treatment is not necessarily required, and the preparation of the catalyst is simple.
The ruthenium-based catalyst thus obtained is preferably 0.1 to 25 as a ruthenium metal based on the total amount of the catalyst including the carrier, from the viewpoint of sufficient catalytic activity, selectivity and economy. About 1% by mass, more preferably 1 to 15% by mass. Further, the second metal component is contained as a metal in a proportion of preferably about 0.1 to 25% by mass, more preferably 0.2 to 15% by mass, based on the total amount of the catalyst including the carrier.
触媒中におけるルテニウム金属量は触媒を硫酸水素アンモニウムで融解処理後、ＩＣＰ発光分析で測定する。また、第二金属成分の金属量は、担体中に珪素を含まない場合は触媒を湿式分解（硫酸−過酸化水素）処理し、珪素を含む場合は触媒をアルカリ溶融処理して、ＩＣＰ発光分析で測定する。 The amount of ruthenium metal in the catalyst is measured by ICP emission analysis after melting the catalyst with ammonium hydrogen sulfate. The amount of metal of the second metal component can be determined by ICP emission analysis by treating the catalyst with wet decomposition (sulfuric acid-hydrogen peroxide) when silicon is not contained in the support, and by alkali-melting the catalyst when silicon is contained.

また、転化率及び１級アミンの選択性などの観点から、原料成分としてのアンモニア／脂肪族アルコールのモル比は、通常０．５〜１０程度、好ましくは２〜７である。アンモニアは、水素と別々に添加することもできるが、これらの混合ガスとして導入することもできる。
水素／脂肪族アルコールのモル比については、バッチタイプの密閉式の場合は、初期の仕込み時のモル比で０．０１〜３．０、特に０．０２〜２．０が好ましい。また、バッチタイプの流通式や固定床流通式の場合は、初期に流通させる水素は脂肪族アルコールに対してモル比で０．０１〜１．０、特に０．０２〜０．８が好ましい。但し、いずれの反応形式においても、反応進行中は必ずしも当該範囲内に限定されない。
Further, from the viewpoints of conversion rate and selectivity of primary amine, the molar ratio of ammonia / aliphatic alcohol as a raw material component is usually about 0.5 to 10, preferably 2 to 7. Ammonia can be added separately from hydrogen, but can also be introduced as a mixed gas thereof.
About the molar ratio of hydrogen / aliphatic alcohol, in the case of a batch-type closed type, the molar ratio at the initial charging is preferably 0.01 to 3.0, particularly preferably 0.02 to 2.0. Moreover, in the case of a batch type flow type or a fixed bed flow type, the hydrogen to be circulated in the initial stage is preferably 0.01 to 1.0, particularly 0.02 to 0.8 in terms of molar ratio with respect to the aliphatic alcohol. However, in any reaction format, the reaction is not necessarily limited to the range within the progress.
