Abstract
Description
疎水性コーティングが施され、30nm以下の平均孔サイズ(孔の平均直径)を有する膜に該溶液を通すことを特徴とする方法に関する。
純物質の流速を測定するために、対応する溶媒が受け器1(図1参照)に導入される。モジュール3には膜4が設けられている。溶液は、ポンプ2によって移送され、圧力が加えられて膜4上にクロス流れとなって移送される。透過液5および濃縮液6からのサンプルを定期的な間隔で採って、比流速(kg/(h・m2・bar))を測定した。
以下の装置を用いた:
受器1:容積5l、ステンレス鋼製、40000hPaまでの圧力に耐える耐圧特性
ポンプ2:ガーザー(Garther)から市販されているギアポンプ
実施例1の装置およびユニット(図1)を使用した。
実施例1の装置およびユニット(図1)を用いた。本実施例では、ユニットに膜Dを用いた。分離される混合物は、2.5lのトルエン、0.132g/lの濃度でトルエン中に溶解しているBINAP(2,2’−ビス(ジフェニルホスフィノ)−1,1’−ビナフチル)、および、0.0929g/lの濃度のPd2(dba)3(トリス(ジベンジリデンアセトン)ジパラジウム)から成る。少なくとも729g/molの分子量を有する錯体化合物Pd−BINAPは、かかる混合物中で形成され、触媒物質として保持される。表3に、正確な実験パラメーターを示す。
実施例1の装置およびユニット(図1)を用いた。本実施例において、Dタイプの膜(表2参照)をユニットに用いた。
