    摘要: After a fluoroaryl borane derivative is precipitated from a solution containing the fluoroaryl borane derivative, a bis (fluoroaryl) borane derivative, and a hydrocarbon solvent and is subjected to first filtration so that the fluoroaryl borane derivative is isolated, a filtrate that has been obtained by the first filtration is cooled and the bis (fluoroaryl) borane derivative is separated and is subjected to second filtration so that the bis (fluoroaryl) borane derivative is isolated. In a case where the solution contains fluorobenzene, the solution is concentrated, so that the fluorobenzene is removed. Thus, it is possible to provide the high-purity fluoroaryl borane derivative and bis (fluoroaryl) borane derivative having no impurity with ease and at a low cost.

    摘要: The present invention relates to an improvement in the recovery of boron values from a mixture of alkali metal borate and alkali metal hydroxide representing discharged fuel from a hydrogen generator apparatus. The mixture is reacted with carbon dioxide and a lower alcohol to form trialkyl borate, alkali bicarbonate and water. A porous water-absorbing material is added to the reaction mixture to absorb water as it forms thereby improving the yield of trialkyl borate. The trialkyl borate is converted to alkali borohydride that is used in the fuel.
