本発明による触媒のパラメータを決定するために、以下の方法を使用する:
DIN 66131に準拠するBET法により決定する。BET法に関する出版物は、J. Am. Chem. Soc. 60、309(1938)にも見出される。測定は、Sorptomatic 1990装置を用いて、77Kにおいて行った。測定前に、試料を2h、523Kにおいて真空化した。BET法による、等温線の線形回帰は、p/p0=0.01〜0.3(p0=730トル)の圧力範囲で行った。
細孔サイズ分布は、窒素吸着測定により、Sorptomatic装置またはTriStar3000装置を用いて77Kにおいて行った。測定前に、試料を2h、523Kにおいて真空化した。吸着だけでなく脱着等温線も決定し、Barrett−Joyner−Halenda法(BJH)による評価に用いた。
X線回折図を、粉末X線回折法(XRD)およびシェラー式による評価により作成した。
例1:
100mLのPTFEビーカーに2回蒸留水75mLを入れて、モノエチレングリコール177.8mgを滴加してから、MoO35397.9mg、V2O51023.9mg、TeO2599.1mg、Nb2O5・xH2O(Nb=63.45重量%)549.5mg、クエン酸540.9mgおよびシュウ酸338.3mgを懸濁させた。テフロンビーカーに栓をして、特殊鋼製オートクレーブボンベ(Edelstahlautoklavenbombe)内に移した。このボンベを圧密に閉め、190℃へと予熱した炉の中の水平回転軸上に固定した。48時間後に、オートクレーブボンベを、炉から取り出し、直ちに流水下で急冷し、続いて氷浴で45分間冷却した。
