1)例えば、図1(108)に例示されるような、ボレート:その場合、A+B-とボレート、例えば無機ボレート、すなわちNaBO2とは、同じである。ナトリウムボロヒドリド以外のボロヒドリドが用いられる場合、対応するボレート(例えばKBO2、LiBO2)が生じるであろう。
2)誘導されるボロヒドリド自体、例えば、NaBH4、KBH4、LiBH4、例えば、図1(101)又は(106)に例示されているNaBH4:その場合、このボロヒドリドは、1:1の化学量論に基づいて必要とされるボロヒドリドに対して過剰である。
3)配合の一部である任意の添加剤、例えば安定化添加剤、好ましくは、アルカリ金属水酸化物、アルカリ金属カーボネート、テトラアルキルアンモニウムヒドロキシド、テトラアルキルアンモニウムカーボネート、テトラアルキルホスホニウムヒドロキシド、テトラアルキルホスホニウムカーボネートのような塩基性の塩、及び任意の種類のアルキルカーボネート、特にイオン性液体水素貯蔵系のために選択されたカチオンと同じカチオンを有するものの群のもの。
カチオンと、ボレートを含むアニオンとを含む第2イオン性液体を、ボロヒドリドにより処理して、放出可能な水素を含む第1イオン性液体を得ることによる水素の貯蔵方法であって、上で記載された(i)、(ii)、(iii)によって特徴付けられ、さらに
(iv)第1イオン性液体が、第1イオン性液体が水混和性のままであり、水素の放出後に第2イオン性液体が水混和性のままである範囲で、無機ボロヒドリド、例えば、NaBH4、KBH4、及び/又はLiBH4をさらに含む
ことを特徴とする、方法を提供する。
アンモニウム塩−例えば、トリメチルアミンと2−ハロプロパンから製造されるハロゲン化物、又は好ましくは、いわゆるカーボネート経路によるメチルカーボネート(如何なる腐食性ハロゲン化物も含まないために好ましい、例えば、WO 2005/021484、WO 2008/052863、WO 2008/052860を参照)−が、ボロヒドリド、例えばナトリウムボロヒドリドと一緒に溶かされ、均質な水溶液(101)が生成される。Y-は、トリメチル−イソ−プロピルアンモニウムカチオンと水溶性の塩を生成できる任意のアニオンであり、好ましくは、CH3CO3、RCO3 -、Cl-、Br-、I-、RSO4 -、R2PO4 -であり(R=C1〜C4アルキルである)、最も好ましくは、CH3CO3 -、RCO3 -である。濃厚溶液が生成されるように、限定された量、例えば、全ての成分を溶かすのに丁度必要な量の水を用いることが好ましい。相分離誘導剤A+B-が添加される(102):A+は、カチオンであり、B-は、アニオンであり、A+B-は、水に強く配位し、ボロヒドリド又は第四級トリメチルイソプロピルアンモニウム塩と反応しない任意の有機又は無機塩である。水と水素結合を形成することによって、A+B-は、反応系から水の溶媒和力を奪って、イオン交換過程と、その後の相分離(塩析)を誘導し、その結果、比較的疎水性のボロヒドリドアニオンが、トリメチルイソプロピルアンモニウムカチオンと一緒になり、比較的親水性のアニオンY-が、ナトリムカチオンと一緒になる。相分離の後、A+B-及びNa+Y-の水溶液(104)は、所望のトリメチルイソプロピルアンモニウムボロヒドリドから分離でき、これは安定で均質な水溶液(103)を生成する(例えば、50重量%を超える濃度が、通常、安定であることが見出された)。
TMiPA+BH4 -+2H2O→TMiPrA+BO2 -+4H2
理論的には、6.8重量%に達する水素で、水素を放出し、これは、2当量の水の質量を含めれば、5.2重量%の水素に相当するが、実際には、系を液体に保つために必要とされる余分の水のせいで、いくらか小さい。WO 2010/081657の手順とは対照的に、本発明に従って調製される溶液は、均質であり、反応に必要な水をすでに含み、WO 2010/081657に記載されているエマルジョンによる場合のように2つの相ではなく、たった1つの相だけが、触媒の表面に接触しなければならないので、より大きな速度で反応する。
