Abstract
Description
1)フルフラールを予備水素化してフルフリルアルコールを得る。その後、高温高圧条件下(175℃、10〜15MPa)で亜クロム酸銅を触媒としてフルフリルアルコールを水素化処理したところ、1,5−ペンタンジオールの収率は約30%と低かった(J. Am. Chem. Soc.,1931,53,1091)。Lu Guanzhongの研究グループは、フルフラールを原料とし、Pt/Co2AlO4を触媒とし、穏やかな条件(140℃、1.5MPa)での接触水素化によって1,5−ペンタンジオールを調製する手法の開発に成功し、24時間後に40%以下の収率の1,5−ペンタンジオールと錯体副産物(Chem. Comm.,2011,47,3924-3926、およびCN102134180)を得た。特許CN102872897 は、水素型超安定Yモレキュラーシーブ(H−USY)担持Pt触媒を使用し、反応の促進剤として塩酸を使用することによって1,5−ペンタンジオールを調製することを開示しており、反応は120℃および1.5MPaで実施される;24時間の反応後に82.6%までの収率で1,5−ペンタンジオールが得られるが、触媒の活性は依然として十分に高くなく、塩酸の存在は深刻な腐食問題を引き起こす。
テトラヒドロフルフリルアルコールの水素化分解によって1,5−ペンタンジオールを調製するために使用される触媒であって、当該触媒は、担体と、担体上に担持された活性成分と、担体上に担持された促進剤とを含み、担体は、窒素含有リガンドでグラフト(grafted)されたポリスチレン、または窒素含有リガンドでグラフトされたシリカゲルであり、当該活性成分は、金属元素Rh、Ir、Pt、Pd、Ru、Auなどのうちのいずれか1つ以上であり、前記促進剤は、金属元素Re、Mo、W、V、Nb、Ta、Mn、Snなどのうちのいずれか1つ以上である触媒。窒素含有リガンドでグラフトされた前記ポリスチレン中の窒素含有リガンドは、イミダゾール、ピリジン、ビピリジンおよび1,10−フェナントロリンのいずれか1つであり、窒素含有リガンドでグラフトされた前記シリカゲル中の窒素含有リガンドは、イミダゾール、ピリジン、ビピリジンおよび1,10−フェナントロリンのいずれか1つである。触媒の総重量に基づいて、前記活性成分は、0.05〜10重量%、好ましくは1〜5重量%の量で担持され、活性成分、促進剤および窒素含有リガンドのモル比は、1:(0.01〜2):(0.05〜4)、好ましくは1:(0.05〜1):(0.1〜2)である。
触媒をテトラヒドロフルフリルアルコールの水素化分解に使用して1,5−ペンタンジオールを調製する場合、良好な反応活性および高い選択性を達成することができる。促進剤は、担体中の窒素含有リガンドと配位することによって触媒に結合し、それによって促進剤の損失が著しく減少し、触媒の安定性が非常に良好である。多数回の再使用、または長期間連続的に使用された触媒の寿命の調査は、触媒が性能に明白な変化を有さず、従って、プロセス全体の製造コストを大幅に低減できることを示唆している。
調製は、段階的に等尺性含浸を用いて行った。先ず、貴金属M(Rh、Ir、Pt、Pd、Ru、Au)の水溶性塩(塩化ロジウム、クロロイリジン酸、クロロ白金酸、塩化パラジウム、塩化ルテニウム、クロロ金酸)を水溶液として別々に調製した。前記調製した水溶液に、表1の比率で粉末状の担体Sを添加し、混合物を均一に混合するまで撹拌した。担体Sに室温で12時間含浸させた後、120℃で12時間乾燥させた。次に、促進剤P(Re、Mo、W、V、Nb、Ta、Mn、Sn)の水溶性塩(レニウム酸アンモニウム、モリブデン酸アンモニウム、メタタングステン酸アンモニウム、バナジン酸アンモニウム、酒石酸ニオブ、酒石酸タンタル、酢酸マンガン、および塩化スズ)を水溶液として別々に調製し、表1の比率に従って、貴金属M構成要素を含浸させた前記含浸させた担体Sに加え、混合物を均一に混合するまで攪拌した。室温で12時間含浸させた後、含浸させた担体Sを120℃で12時間乾燥させ、活性成分の含有量が異なる触媒を得た。
本発明の触媒評価は、5000mLの反応器容積を有し、ステンレス鋼製の回分式反応器中で行った。一定量の触媒を反応器に添加し、還元温度150℃、水素圧0.3MPa、水素流量1.5L/分で、触媒をその場で4時間還元した。還元後、温度を反応温度まで下げ、一定濃度のテトラヒドロフルフリルアルコール水溶液3000gを加え、温度を反応温度に調整し、一定圧力の水素を反応器に入れて反応を行った。反応は、一定時間後に完了した。具体的な反応条件は、表2に示した。温度を下げ、圧力を解放した後、液体試料を採取した。液体試料を、前記のようにDB−5キャピラリーカラムおよび火炎イオン化検出器(FID)を備えたガスクロマトグラフを用いて分析した。
本発明の触媒評価は、外径40mm、内径20mm、長さ1000mmのステンレス鋼管である固定床反応器中で行った。50gの触媒を反応器に装填した。反応の前に、装填した触媒を、還元温度150℃、水素圧0.3MPa、水素流量1.5L/分で、その場で4時間還元した。還元後、温度を反応温度まで下げ、水素/触媒の体積空間速度を1000h−1に設定し、テトラヒドロフルフリルアルコール水溶液の流量をテトラヒドロフルフリルアルコール供給液/触媒の所望の質量空間速度に調整し、圧力を所望の反応圧力に調整した。具体的な反応条件は、表3に示した。液体試料をオンラインで採取し、前記のようにDB−5キャピラリーカラムおよび火炎イオン化検出器(FID)を備えたガスクロマトグラフを用いて分析した。
本出願における触媒の利点をより良く具体化するために、担体として、窒素含有リガンドでグラフトしないで、ポリスチレンおよびシリカゲルを直接、使用することによって10個の代表的な触媒を調製した。即ち、金属および促進剤の含有量、調製方法および実施例は、それぞれ、1#、2#、10#、11#、13#、19#、21#、23#、26#および27#の触媒について記載したものと同じであった。
本出願における触媒の利点をより良く具体化するために、比較例における触媒1−1#〜1−10#を回分式反応器で評価し、その評価条件は、実施例28〜54における触媒1#、2#、10#、11#、13#、19#、21#、23#、26#および27#について記載したものと同じであった。
