Abstract
【解決手段】本発明の無機分離膜は、セラミックス多孔質支持体1上にシリカライトナノクリスタル層2を形成し、更にその上面に多孔質の無機保護層3を形成したものである。シリカライトナノクリスタル結晶径は、150nm以下とすることが好ましく、シリカライトナノクリスタル層の厚みは、1.0μm〜4.0μmとすることが好ましい。この分離膜は、セラミックス多孔質支持体1をシリカライトナノクリスタルの分散液中に浸漬し、その内部を減圧することによりシリカライトナノクリスタルを積層させ、これをさらにゼオライト合成溶液中に浸漬したうえ加熱して無機保護層3を水熱合成し,さらに液相酸化により有機成分を除去する方法で製造できる。

Description
T. Masuda et al., Separation and Purification Technology, 32,181(2003)
図1は本発明の無機分離膜の膜構造を模式的に示す断面図であり、1はセラミックス多孔質支持体、2はその上面に積層されたシリカライトナノクリスタル層、3は更にその上面に形成された多孔質の無機保護層である。セラミックス多孔質支持体1の材質は特に限定されるものではないが、ここでは耐酸性に優れるアルミナ質のろ過体(円筒形アルミナフィルター)を使用した。
先ず水酸化ナトリウムによりpHを10に調整した蒸留水中にシリカライトナノクリスタルを投入し、超音波により15分間分散させた。この液中に、外径11mm、長さ55mmのアルミナフィルターを浸漬し、その内部を吸引することによってアルミナフィルターの外周面に1.3〜4.0μmの厚さのシリカライトナノクリスタル層を形成した。
