。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for producing a ruthenium nitrate solution that is a raw material for a catalyst or a starting material for the synthesis of a ruthenium compound using the properties of ruthenium. be.
(従来技術とその問題点)
従来ルテニウムの持つ特性を利用した触媒の原料、ある
いはルテニウム化合物の合成のための出発原料とては塩
化ルテニウムや塩化ルテニウム酸塩を用いていた。(Prior art and its problems) Conventionally, ruthenium chloride and ruthenate chloride have been used as raw materials for catalysts that utilize the properties of ruthenium, or as starting materials for the synthesis of ruthenium compounds.
しかし、最近の技術開発に伴い塩素イオンを含有するこ
とが触媒性能の障害となることや各種のルテニウム化合

強く要望されていたが、該硝酸ルテニウム溶液の製造方
法がなくその開発が待たれていた。However, with recent technological developments, the inclusion of chlorine ions impedes catalyst performance, and a ruthenium nitrate solution has been strongly desired as a starting material for synthesizing various ruthenium compounds. There was no manufacturing method for this, so its development was awaited.

特徴とする硝酸ルテニウム溶液の製造方法である。(Means for Solving the Problems) The present invention provides a method for producing a ruthenium nitrate solution, in which ammonia is added to a ruthenium chloride solution to neutralize it to produce ruthenium hydroxide, and then the ruthenium hydroxide is processed by a decanting method. Separate and wash, add nitric acid to ruthenium hydroxide, heat and dissolve in a hot water bath, cool, measure the chlorine ion concentration in the solution, add an equivalent amount of silver ions to the amount of chlorine ions, and stir. The method of producing a ruthenium nitrate solution is characterized in that the compound added as the silver ion is silver nitrate or silver oxide.
以下、本発明の製造方法について詳細に説明する。Hereinafter, the manufacturing method of the present invention will be explained in detail.
塩化ルテニウム溶液にアンモニア水を加えて中和し水酸
化ルテニウムを生成し、濾過分離して水酸化ルテニウム
を水で十分に洗浄する。Aqueous ammonia is added to the ruthenium chloride solution to neutralize it to produce ruthenium hydroxide, which is separated by filtration and the ruthenium hydroxide is thoroughly washed with water.
塩化ルテニウム溶液の濃度は5〜100g/I2であれ

ア水を用いるのは他のアルカリ塩、例えば水酸化ナトリ
ウムや水酸化カリウムの水溶液を用いるとナトリウムや
カリウムのイオンが混入して分離が困難となるためで、
アンモニア水であれば加熱分離ができるためである。The concentration of the ruthenium chloride solution should be 5 to 100 g/I2, and to generate ruthenium hydroxide, aqueous ammonia is not suitable for other alkali salts, such as sodium hydroxide or potassium hydroxide. This is because ions such as potassium and potassium ions are mixed in, making separation difficult.
This is because ammonia water can be separated by heating.
また、生成させた水酸化ルテニウムの濾過分離、洗浄の
方法としては傾斜法により行うのが該水酸化ルテニウム
の洗浄に適し、洗浄は先ず、希アンモニア水(0,1%
程度)で2〜3回行い、次いで、純水で2〜3回洗浄す
ると塩素イオンの洗浄に効果があるものである。In addition, as a method for filtering, separating and washing the generated ruthenium hydroxide, a gradient method is suitable for washing the ruthenium hydroxide.
It is effective to wash chlorine ions by washing with pure water 2 to 3 times and then washing with pure water 2 to 3 times.
次いで、該水酸化ルテニウムに硝酸を加えて加熱溶解し

オン量を算出してその当量の銀イオンを加えて塩化銀を
生成させ一夜間室温で静置させたのち、塩化銀の沈澱と
硝酸に未溶解物を濾過分離して硝酸ルテニウム溶液を得
ることができる。Next, nitric acid was added to the ruthenium hydroxide and dissolved by heating, and after cooling, the chlorine ions in the solution were measured, the amount of chlorine ions was calculated, and the equivalent amount of silver ions was added to produce silver chloride, which was then dissolved overnight. After standing at room temperature, silver chloride precipitates and substances not dissolved in nitric acid are separated by filtration to obtain a ruthenium nitrate solution.
上記で用いる硝酸の濃度は特に限定されないが溶解速度
から6規定以上のものが良く、加熱溶解の方法としては
湯浴中で行うのが良い。The concentration of the nitric acid used above is not particularly limited, but it is preferably 6N or more in view of the dissolution rate, and the dissolution by heating is preferably carried out in a hot water bath.
その理由は、硝酸ルテニウムの収率を高めるためで、加
熱温度が高すぎると酸化物が生成しやすくなるからであ
る。The reason for this is to increase the yield of ruthenium nitrate, and if the heating temperature is too high, oxides are likely to be produced.
また、塩素イオンを測定するのは水酸化ルテニウムを洗
浄した際のバラツキが生ずるためと、該塩素イオンを除
くために加える銀イオンが過剰となることをさけるため
であり、測定方法は銀イオンによる比濁法でよい。In addition, the reason for measuring chlorine ions is to avoid variations that occur when ruthenium hydroxide is washed, and to avoid excessive silver ions being added to remove the chlorine ions.The measurement method is based on silver ions. Nephelometry is sufficient.
加える銀イオンはO0l規定前後の硝酸銀溶液を用いる
と良く、他に酸化銀を加えても硝酸銀と同様の結果を得
ることができるものである。It is preferable to use a silver nitrate solution with a concentration of around O0l as the silver ions to be added, and even if silver oxide is added, the same results as with silver nitrate can be obtained.
なお、−夜間静置させるのは塩化銀の沈澱を熟成させる
効果があり濾過分離しやすくするためである。The reason why the silver chloride is allowed to stand overnight is that it has the effect of ripening the silver chloride precipitate and makes it easier to separate it by filtration.
塩化銀の沈澱と硝酸に未溶解物を濾過分離する方法は特
に限定するものではないが、パルプノ々ウダや活性炭粉
末を加えて濾過分離することは微量の塩化銀の沈澱と硝
酸に未溶解物を濾過分離するのに効果的であることは言
うまでもない。The method of filtering and separating silver chloride precipitates and undissolved substances in nitric acid is not particularly limited, but adding pulp powder or activated carbon powder and separating by filtration is a method that can remove a trace amount of silver chloride precipitates and undissolved substances in nitric acid. Needless to say, it is effective for filtering and separating.
