触媒が、非酸性酸化物層によって被覆された焼結金属繊維(SMF)をベースとした構造体触媒であって、非酸性酸化物層がMgO、ならびに任意選択によりAl2O3、TiO2、ZrO2、CeO2、La2O3(ランタニド系列から作られる他の酸化物もまた適している)およびGa2O3からなる群から選択される少なくとも1種の他の金属酸化物を含み、前記金属酸化物層にPdナノ粒子が含浸されている構造体触媒である
ことを特徴としている。
[実施例1:構造体触媒の調製(0.2%Pd/5%(MgO+Al2O3)/SMFss]
AISI316Lステンレス鋼焼結金属繊維パネル(SMFSS、Bekaert Fibre Technology)をアセトン(Fluka、≧99%)で洗浄し、トルエン(Fluka、≧99.7%)中で30分間煮沸し、室温で空気乾燥させた。酸化物層が金属繊維表面に接着しやすくなるように、このフィルタをさらに空気中、450℃で2時間酸化させた(傾斜−20°min−1)。
実施例1に記載のようにして清浄化したSMFFecralパネルに、Zn酸化物層をディップコーティングした。ZnO前駆体溶液は次のように調製した:18.3gのモノエタノールアミンおよび12.8gのアセトインを、0.75lのイソプロパノールに攪拌しながら溶解した。その後、この混合物に65.8gのZn(CH3COO)2・2H2Oを加え、攪拌しながら溶解した。
MgOをZnOに代えた以外は実施例1に記載したようにして、0.2%Pd/5%(ZnO+Al2O3)/SMFSS触媒を調製した。
溶媒中における水素化はすべて、図1に示した実験装置を用いて行った。SMFベースの触媒(0.8g、例1、2または3)を攪拌機に固定した。60cm3の有機溶液(溶媒+出発物質(約32%)を反応器に仕込んだ。反応器をN2で3回パージし、反応温度まで加熱し、H2で加圧した。反応中、圧力を一定に維持した。反応混合物を攪拌した(2000rpmで)。反応の進行は、試料(約0.5cm3)を抜き取り、分析することにより追跡した。
溶媒を使用しなかった以外は、実施例4に記載のようにして水素化を行った。この場合、60cm3の出発物質を反応器に仕込んだ。
SMFベースの構造体触媒を、商業的に入手可能な、粉末活性炭に担持させたPd、10%Pd/C(約0.04g、Fluka)に代えた以外は実施例4に記載のようにして水素化を行った。この場合、粉末触媒は液相に混合した。
プソイドイオノン(式(Ia)で示される化合物≡化合物A1)
の水素化を、実施例1の触媒を使用して、実施例5に記載のようにして行った。得られた濃度−時間プロファイルおよび反応条件を図2に示す。
の濃度が極大値を示す。A1が完全に転化した後、式(IIIa)で示される化合物(≡化合物A3)
の生成が始まる。A4
の生成は無視できるほどである。アルコール(A5)の生成
は認められなかった。
10%Pd/C触媒(Fluka)を使用し、実施例5に記載のようにして、プソイドイオノンの水素化を行った。得られた濃度−時間プロファイルおよび反応条件を図3に示す。この場合、A2の生成は認められず、A3とA4が反応の開始直後から生成する。
例1〜3に記載したようにして調製した触媒を使用し、実施例5に記載のようにして、プソイドイオノンの水素化を行った。測定した触媒の初期活性RPIと選択率SA2を表1に示す。
