再生含量を含む、フタレート、イソフタレートおよびテレフタレート、特にフタレートの本発明による水素化は、一般に50℃〜250℃、有利に70℃〜220℃の温度で行なわれる。圧力は、一般に10バールを上廻る。
上記の触媒が使用される水素化法の場合には、或る程度の触媒の可使時間後に不活性化を観察することができる。このように不活性化されたルテニウム触媒は、洗浄によって元来の活性の状態に戻すことができる。活性は、初期値の90%を上廻るまで、特に95%を上廻る、特に有利に98%を上廻る、殊に99%を上廻る、殊に有利に99,5%を上廻るまで再び形成させることができる。不活性化は、触媒上に吸着された水の痕跡または残分に帰因する。これは、意外なことに不活性ガスでの洗浄によって逆転させることができる。従って、本発明による再生法は、触媒の乾燥または触媒からの水の除去とも呼称することができる。
(a)フタレート、イソフタレートまたはテレフタレートの少なくとも1つならびにルテニウム触媒の準備;
(b)触媒が減少された水素化活性を有するまでの、ルテニウム触媒の存在下で水素との接触による、使用された芳香族化合物の水素化、
(c)不活性ガスでの洗浄による触媒の再生、
(d)場合による工程(a)〜(c)の繰り返しを有する触媒再生工程を有する、フタレート、イソフタレートおよびテレフタレート、および相応する酸、特にフタレートをルテニウム触媒の存在下で水素化するための統合された方法である。
0.44cm3/gの全体積、この場合50nm〜10000nmの範囲内の直径を有する細孔0.09cm3/g(全細孔体積の20%)および2nm〜50nmの範囲内の直径を有する細孔0.35cm3/gが形成されているものとし、11nmの範囲の平均細孔直径および286m2/gの表面積を有する3〜5mmの球の形のメソ多孔質/マクロ多孔質の酸化アルミニウム担体を、硝酸ルテニウム(III)水溶液で含浸した。この場合、含浸中に吸収された溶液の容量は、使用された担体の細孔容積にほぼ相当した。引続き、硝酸ルテニウム(III)水溶液で含浸した担体を120℃で乾燥し、水素流中で200℃で活性化した(還元した)。こうして得られた触媒は、触媒の質量に対してルテニウム0.5質量%を含有していた。ルテニウムの表面積は、0.72m2/gであり、ルテニウムと担体表面積との比は、0.0027であった。
上記のように製造された触媒(0.5%Ru/γ−Al2O3)上での水蒸気の吸着測定によって、水に対する触媒の親和力を測定した。
ジイソノニルフタレートをDINCHに水素化する場合には、3ヶ月の運転時間後に100ppm未満の残留フタレート含量が触媒負荷量の連続的な減少(=DINPの供給量の減少)によってなお達成されることが確認される。温度および圧力上昇は、全く改善を生じない。試験装置は、次に記載されている:
この装置は、2個の順次に接続された反応器1と2からなる(図1)。反応熱は、冷却によって反応器1の再循環回路から取り出される。2つの反応器1と2(図中には、1および2で略記した)を下降流モードで運転する。Aは、DINPの供給量であり、Bは、H2の供給量である。
