Description
R1及びR2は相互に無関係にもう1つのメチロール基又は1〜22個のC原子を有するアルキル基又は6〜33個のC原子を有するアリール基又は6〜33個のC原子を有するアラルキル基を表す]のメチロールアルカナールを液相中で水素化触媒上で接触水素化するための方法において、少なくとも1種の3級アミン、無機塩基又は無機酸又は有機酸を水素化フィードに添加することにより、水素化排出物においてpH値を7.0〜9.0に調節することを特徴とする方法により解決される。
実施例1
ヒドロキシピバリンアルデヒドからネオペンチルグリコールへの水素化
水素化フィード
イソブチルアルデヒド1.1モルを、40%溶液の形のホルムアルデヒド1モル、及び、イソブチルアルデヒドに対して4モル%のトリメチルアミンと、75℃で1時間にわたって撹拌した。常圧で易揮発性物質、例えばイソブチルアルデヒド及び水の一部を留去することによって反応溶液を濃縮した。得られた塔底生成物は、ヒドロキシピバリンアルデヒド75質量%、水20質量%及びその他の有機副成分約5質量%からなっていた。
この項目で以下に記載される全てのパーセント数値は、他に記載がない限り質量%を表す。記載されたパーセント数値の組成は、完成触媒の酸化物成分に関するものである。
出発溶液として、水素化フィードとして上記された混合物を利用した。この混合物に、トリメチルアミンの15質量%水溶液(水素化フィードに対して)0〜7質量%(ないし、比較例ではクエン酸の5質量%水溶液(水素化フィードに対して)2〜5質量%)を添加し、それぞれ第1表に示される水素化排出物のpH値に調節した。そのように得られた水素化供給物を、液体循環式(循環物:供給物=10:1)で触媒負荷0.4kgHPA/lkat×hでありかつトリクル方式である水素化反応器に、40バールで120℃で触媒を介してポンプ輸送した。
ジメチロールブタナール(DMB)からトリメチロールプロパン(TMP)への水素化
水素化フィード
水素化フィードをPCT/WO98/28253の実施例6により製造した。
Cu/TiO2触媒J PCT/WO99/44974 300mlを管状反応器中で190℃で、水素5体積%及び窒素95体積%(全体積150Nl/h)からなる混合物の導通により常圧で24時間活性化させた。
出発溶液として、水素化フィードとして上記された混合物を利用した。この混合物に、クエン酸の10%水溶液(水素化フィードに対して)0〜3質量%を添加し、第2表に示される水素化排出物のpH値に調節した。そのように得られた水素化供給物を、トリクル方式でH2圧80バールで120℃に加熱された反応器に導通させた。負荷はジメチロールブタナール(DMB)0.4kg/(lkat.*h)であった。水素化排出物の一部を供給物に再度混合した(循環方式)。循環物:供給物の割合は10:1であった。第2表に、種々のpH値での数日間にわたる平均転化率及び選択率を示す。反応器出口の試料から室温でpH値を測定した。
