Abstract
Description
特許文献1~3には、触媒存在下で、H2/CO混合ガスを用いてシアンノルボルネンをヒドロホルミル化させ、ホルミルシアンノルボルナンを製造する方法が開示されている。特許文献1および2には、触媒として金属化合物を用いた例が開示されている。なお、目的化合物を高選択的に得ることができ、反応圧力を低く抑制することができることから、触媒としてロジウム錯体が好ましく用いられている。
特許文献4には、遷移金属触媒と三価のリン化合物の存在下で、H2/CO混合ガスを用いてオレフィン系化合物をヒドロホルミル化する方法が開示されている。そして、金属触媒の含量は、触媒組成物の重さまたは体積を基準に、遊離金属含量が10~1000ppmであると記載されている。
特許文献6の実施例には、ロジウム触媒およびビスホスファイトの存在下で、7-オクテナールをヒドロホルミル化させた例が記載されている。7-オクテナール 1molに対しロジウムは3ppmmol程度で用いられており、ロジウム原子/リン原子はモル比で1/20であると記載されている。一方、特許文献6の0084段落には、金属1モルに対してリン原子換算で2~1000モルが好ましく、1000モルを超える場合は、反応速度が極めて小さくなる傾向があると記載されている。
また、特許文献7の実施例には、シクロヘキセンを、3ppmのロジウムの存在下でヒドロホルミル化させた例が記載されている。
なお、シアノノルボルネン化合物のヒドロホルミル化反応における従来の技術水準としては、特許文献1の実施例5に記載のように、基質に対する金属の量が55ppmである。しかしながら、選択率が87.2%と低く改善の余地があった。
すなわち、本発明の課題は、従来の使用量で金属を用いた場合と同等の生産性を維持しつつ、レアメタルである希少金属の使用量を低減し、有効活用する技術を確立することを課題とする。
