Description
実施例1〜4は、低シリカ含有量のアルミナ材料の、特にそのような材料をモリブデンと組み合わせて担体として使用するときの、汚染となる濃度のヒドロキシケトンを含むフェノール生成物の処理における有効性を測定するために使用した実験手順を記載する。これらの実施例は、低シリカ含有量のアルミナが、ベンゾフラン副生成物を過剰に生成せずにフェノール生成物中に含まれるヒドロキシケトンを転換するのに、有効に使用できることを示している。
純粋なフェノールからヒドロキシアセトン(HAまたはアセトール)を990ppmw、1−ヒドロキシ−2−ブタノン(1HB)を520ppmw、3−ヒドロキシ−2−ブタノン(3HBまたはアセトイン)を490ppmw含む供給原料を調製し、約8%のモリブデンを含むアルミナ触媒と145℃で2時間接触させた。触媒は、あらかじめ活性化し乾燥した。別々の3回の実験についてヒドロキシケトンの転換率は平均で、HA、1HB、および3HBについてそれぞれ98、98、および100%であった。およそ、HAの約6%が2−メチルベンゾフランに転換され、1HBの3%が2−エチルベンゾフランに転換され、3HBの3%が1,3−ジメチルベンゾフランに転換された。
純粋なフェノールからヒドロキシアセトン(HAまたはアセトール)を990ppmw、1−ヒドロキシ−2−ブタノン(1HB)を520ppmw、3−ヒドロキシ−2−ブタノン(3HBまたはアセトイン)を490ppmw含む供給原料を調製し、約4%のモリブデンを含むアルミナ触媒と145℃で2時間接触させた。触媒は、あらかじめ活性化し乾燥した。別々の3回の実験についてヒドロキシケトンの転換率は平均で、HA、1HB、および3HBについてそれぞれ84、87、および98%であった。対応するベンゾフランの選択性は、平均で約6、3、および2.5%であった。
純粋なフェノールからHAを990ppmw、1HBを520ppmw、3HBを490ppmw含む供給原料を調製し、あらかじめ活性化し乾燥した、モリブデンを含まないアルミナ触媒と145℃で2時間接触させた。ヒドロキシケトンの転換率は、HA、1HB、および3HBについてそれぞれ18、15、および8%であった。対応するベンゾフランの選択性は、約2、0.5、および2%であった。
純粋なフェノールからHAを990ppmw、1HBを520ppmw、3HBを490ppmw含む供給原料を調製し、触媒は添加せずに145℃で2時間加熱した。別々の3回の実験についてヒドロキシケトンの転換率は平均で、HA、1HB、および3HBについてそれぞれ5、5、および7%であった。対応するベンゾフランの選択性は、平均で約3、0.1、および3%であった。
