外径8mm、長さ6mmおよび壁厚1.6mmを有するステアタイト(珪酸マグネシウム)リング1400gを被覆ドラム中で160℃に加熱し、アクリル酸/マレイン酸コポリマー(質量比=75:25)からなる有機結合剤13.8gと一緒に、21m2/gのBET表面積を有するアナターゼ466g、バナジルオキサレート67.2g、三酸化アンチモン14.4g、リン酸水素アンモニウム3.15g、硫酸セシウム2.87g、水721gおよびホルムアミド149gからなる懸濁液を噴霧した。こうして被覆した触媒活性組成物は平均してリン(Pとして計算して)0.16質量%、バナジウム(V2O5として計算して)7.5質量%、アンチモン(Sb2O3として計算して)3.2質量%、セシウム(Csとして計算して)0.40質量%および二酸化チタン88.74質量%からなる。

B1.例A1およびA2からの本発明による触媒および例3からの比較触媒を使用する無水フタル酸の製造
内径16mmを有する長さ80cmの鉄管に触媒A1、A2またはA3(被覆したステアタイト球)を層長さ66cmに充填した。温度を調節するために、鉄管を電気加熱ジャケットにより包囲した。空気標準m3当たり98.5質量%o−キシレン60gを充填した空気360標準l/hを管に上から下に貫流した。得られた結果を以下の表に示す。
4.85(9.8)、3.50(14.8)、3.25(39.9)、2.93(100)、2.78(36.2)、2.55(35.3)、2.43(18.6)、1.97(15.2)、1.95(28.1)、1.86(16.5)、1.83(37.5)、1.52(23.5)。
触媒A5.0.80モル、触媒A4.1.40モルおよび引き続きプレ触媒A3(被覆したステアタイトリング)0.80モルを、内径25mmを有する長さ3.85mの鉄管に下から上に導入した。温度を調節するために、鉄管を塩溶融物により包囲した。空気標準m3当たり98.5質量%o−キシレン80gを充填した空気4.0標準m3/hを管に上から下に貫流した。353〜360℃の塩浴温度で115.5質量%の平均PA収率が達成された(この収率は100%純粋o−キシレンに対する無水フタル酸質量%の量である)。変換率は99.94%より高く、反応器出口での残留フタリド含量は0.35質量%未満であった。
触媒A5.0.80モル、触媒A4.1.40モルおよび引き続きプレ触媒A1.0.80モルを使用して例B2の工程を繰り返した。平均PA収率117.2質量%が達成された。
触媒A5.0.90モル、触媒A4.1.60モルおよび引き続きプレ触媒A1.0.50モルを使用して例B3の工程を繰り返した。平均PA収率116.7質量%が達成された。変換率は999.94%より高く、反応器出口での残留フタル酸含量は0.35質量%未満であった。この例は本発明の触媒を使用する場合に、銀−酸化バナジウム触媒の層の長さが例B1よりかなり短くても高いPA収率が達成できることを示す。
