【発明の詳細な説明】 発明の技術分野 本発明は、過レニウム酸の製造法に関する。[Detailed description of the invention] Technical field of invention The present invention relates to a method for producing perrhenic acid.
発明の従来技術
過レニウム酸は、石油精製における触媒等に広
く用いられる物質である。Prior Art of the Invention Perrhenic acid is a substance widely used as a catalyst in petroleum refining.
過レニウム酸は、一般には過レニウム酸カリウ
ムを水素気流中で還元し、K2Oを水で除き、
ReO2とReとから成る残留物を30％過酸化水素で
酸化し製造されている。 Perrhenic acid is generally produced by reducing potassium perrhenate in a hydrogen stream and removing K 2 O with water.
It is produced by oxidizing a residue consisting of ReO 2 and Re with 30% hydrogen peroxide.
上記方法においては、処理フローシートが長い
ことから工業上、製造コスト、処理装置を考慮し
た場合好ましい方法ではなかつた。 In the above method, since the treatment flow sheet is long, it is not a preferable method from an industrial standpoint, manufacturing cost, and processing equipment.
そこで、発明者等が、鋭意検討した結果以下の
発明をなした。 Therefore, the inventors made the following invention as a result of intensive study.
発明の構成
即ち、本発明は、
(1) 過レニウム酸カリウムを含む液中のカリウム
を除去するに際し、陽イオン交換樹脂と前記液
を接触し、カリウムを吸着除去する過レニウム
酸の製造法。Components of the Invention That is, the present invention provides: (1) A method for producing perrhenic acid in which, when removing potassium from a solution containing potassium perrhenate, the solution is brought into contact with a cation exchange resin and potassium is adsorbed and removed.
(2) 液温度が、30〜50℃である(1)記載の過レニウ
ム酸の製造法。(2) The method for producing perrhenic acid according to (1), wherein the liquid temperature is 30 to 50°C.
発明の具体的説明
過レニウム酸カリを水に溶解する。または、過
レニウム酸カリの溶液を処理対象液とする。DETAILED DESCRIPTION OF THE INVENTION Potassium perrhenate is dissolved in water. Alternatively, a solution of potassium perrhenate is used as the liquid to be treated.
該液と陽イオン交換樹脂と接触し、カリウムそ
の他の微量の不純物を液から除去する。 The liquid is brought into contact with a cation exchange resin to remove potassium and other trace impurities from the liquid.
このときの液のPHは、１以下であることが好ま
しい。溶解度が、充分あるからである。 The pH of the liquid at this time is preferably 1 or less. This is because it has sufficient solubility.
接触の容量比は、上該樹脂に対し、１〜３倍容
量／時間の上記処理液を接することが好ましい。 The volume ratio of the contact is preferably 1 to 3 times the volume/hour of the treatment liquid to the resin.
処理液温度は常温から50℃で良いが、好ましく
は、30〜50℃である。 The temperature of the treatment solution may range from room temperature to 50°C, but preferably from 30 to 50°C.
温度があまり低いとKReO4の溶解度が低くな
り、取扱い液量が多くなるためである。 This is because if the temperature is too low, the solubility of KReO 4 will be low and the amount of liquid to be handled will be large.
また、あまり温度が高いと、樹脂が劣化し好ま
しくないためである。 Moreover, if the temperature is too high, the resin will deteriorate, which is not preferable.
陽イオン交換樹脂としては、例えばスチレン系
強酸性陽イオン交換樹脂がある。 Examples of the cation exchange resin include styrene-based strongly acidic cation exchange resins.
例えば、下記の構造のものである。 For example, it has the following structure.
陽イオン交換樹脂と、過レニウム酸カリ溶液と
接する前は、過工程を経由し、不溶解残渣は予
め除去しておくことが望ましい。 Before contacting the cation exchange resin with the potassium perrhenate solution, it is desirable to remove undissolved residues in advance through a step.
また、使用する溶解水等は、純水を用いること
が好ましい。製品となる過レニウム酸が着色する
ことがあるためである。 Moreover, it is preferable to use pure water as the dissolution water and the like. This is because the perrhenic acid product may become colored.
陽イオン交換樹脂と接触した処理後液中には、
Ｋのほとんど含まない液となつている。例えば、
処理液中0.001ｇ／以下となるのである。 In the treated solution that came into contact with the cation exchange resin,
The liquid contains almost no K. for example,
The amount is 0.001g/or less in the processing solution.
陽イオン交換樹脂には、カリウムおよび他の不
純物が回収された。他の不純物としては、Fe，
Seがあつた。レニウムは、ほとんど吸着されず、
分布率としては0.1％以下であつた。 Potassium and other impurities were recovered in the cation exchange resin. Other impurities include Fe,
Se was hot. Rhenium is hardly adsorbed,
The distribution rate was less than 0.1%.
陽イオン交換樹脂は、吸着後、好ましくは純水
で洗浄される。過レニウム酸に着色が生じないよ
うにするためである。 After adsorption, the cation exchange resin is preferably washed with pure water. This is to prevent coloring of perrhenic acid.
発明の効果
以上のように本発明を実施することにより、以
下の効果を得ることができた。Effects of the Invention By implementing the present invention as described above, the following effects could be obtained.
(1) 高純度の過レニウム酸が、容易に得られる。(1) Highly purified perrhenic acid can be easily obtained.
(2) 取扱い液量を、極力減らした状態で処理が可
能である。(2) Processing is possible with the amount of liquid handled being reduced as much as possible.
(3) 活性炭を使用せずとも、過レニウム酸に着色
が生じないものを製造し得る。(3) It is possible to produce perrhenic acid that does not cause coloration without using activated carbon.
実施例
過レニウム酸カリを純水に溶解し、過し溶解
後液と陽イオン交換樹脂であり、スチレン系強酸
性陽イオン交換樹脂SK−IB（商品名；三菱化成
(株)製造）と接触させた。Example Potassium perrhenate was dissolved in pure water, and the solution after filtration and cation exchange resin was styrene-based strongly acidic cation exchange resin SK-IB (product name: Mitsubishi Kasei Co., Ltd.).
Manufacturing Co., Ltd.).
液温度40℃、液組成はRe5.4ｇ／、K1.16
ｇ／であつた液が、接触後、後液中にRe5.3
ｇ／，K0.001ｇ／以下の液が得られた。 Liquid temperature 40℃, liquid composition Re5.4g/, K1.16
After contact, the solution that was at
g/, K0.001 g/or less liquid was obtained.
上記樹脂は、接触後塩酸で、吸着したＫを除い
た。 After contacting the resin, adsorbed K was removed with hydrochloric acid.
上記の実施において用いた水は、純水を用いた
ため、活性炭を用いずとも過レニウム酸には着色
が生じなかつた。 Since the water used in the above implementation was pure water, perrhenic acid was not colored even if activated carbon was not used.
