dc.description.abstract1,5-戊二醇為合成高價值聚合物之重要單體,一般經由石油來源合成。但石油來源中缺乏五碳化合物,因此1,5-戊二醇實為工業合成程序中之副產物,進而使得全球的年產量相當低 (3000噸/年)。然而,隨著新聚合物的開發,1,5-戊二醇的需求量逐年成長,造就了1,5-戊二醇的高單價。因此,自生物質轉換所得之糠醛生產1,5-戊二醇的反應開發逐漸受到重視。 近年來,許多固體觸媒被成功應用於轉換糠醛至1,5-戊二醇,但皆須使用高壓氫氣搭配高溫的反應條件,如此嚴苛之反應環境導致製程耗能與不易控制等問題。本研究成功開發能於溫和條件下,生產75%高產率之1,5-戊二醇反應,其觸媒為金屬有機框架衍生氧化鋁支撐式白金觸媒,並搭配硼氫化鈉於水相環境中轉換糠醛為1,5-戊二醇。此反應之路徑分為兩步驟,糠醛先被氫化為糠醇,糠醇之呋喃環直接行開環反應,開環後之反應中間體再緊接著被氫化成為1,5-戊二醇。其中,硼氫化鈉不僅僅只扮演氫源之角色,其水解產物之衍生產物硼酸能協助開環反應步驟之進行。zh_TW
dc.description.abstract1,5-Petanediol (1,5-PD) is an essential chemical for industrial production of polymer and is mainly derived from petroleum. Unfortunately, 1,5-pentanediol is a side product in petroleum process. Thus, the worldwide capacity is low, and with increasing demand, the price of 1,5-pentanediol rises. In order to enhance higher capacity, the synthesis of 1,5-pentanediol through biomass process. In the biomass process, 1,5-pentanediol is converted from furfural through the ring-opening hydrogenation process which requires severe conditions leading to large energy consumption and system-controlling difficulties. Therefore, we develop a metal organic framework derived alumina supported platinum catalyst which enhances an ability to convert furfural into 1,5-pentanediol with high yield (75%) under mild condition assisted by sodium borohydride. The reaction pathway is proved that the furan ring of the furfuryl alcohol, hydrogenation product of furfural, is firstly open and hydrogenated into 1,5-pentanediol. The role of sodium borohydride is not just a hydrogen source but also an origin of the boric acid, a helping reagent of ring-opening step.en
