Abstract
Description
本発明は、繊維状タンパク質への金属触媒の担持方法に関する。 The present invention relates to a method for supporting a metal catalyst on a fibrous protein.
従来より、パラジウム−炭素触媒に代表されるような、酸化又は還元反応に使用される不均一系の金属触媒が数多く知られている。従来の不均一系触媒は、容易に発火し易い、触媒の回収又は再利用等が煩雑になる等の問題点があった。このような問題点を解決するため、近年、不均一系の金属触媒を担体に担持させたものが開発されており、中でも不均一系の金属触媒を繊維状タンパク質に担持させたもの(例えば絹フィブロイン担持パラジウム[Pd/Fib]触媒等)が、従来の金属触媒と官能基選択性等の触媒活性が異なる点から注目を集めている(例えば非特許文献1、非特許文献2、非特許文献3)。 Conventionally, many heterogeneous metal catalysts used for oxidation or reduction reactions, such as palladium-carbon catalysts, are known. Conventional heterogeneous catalysts have problems such as being easy to ignite, and complicated recovery or reuse of the catalyst. In order to solve such problems, in recent years, a material in which a heterogeneous metal catalyst is supported on a carrier has been developed. Among them, a material in which a heterogeneous metal catalyst is supported on a fibrous protein (for example, silk Fibroin-supported palladium [Pd / Fib] catalysts, etc.) are attracting attention because they differ from conventional metal catalysts in catalytic activity such as functional group selectivity (for example, Non-Patent Document 1, Non-Patent Document 2, Non-Patent Documents). 3).
これら不均一系の金属触媒を繊維状タンパク質に担持させたものの製造方法としては、例えば〈1〉パラジウムを絹に吸着させた触媒を高温、高圧、強酸性条件下で調製する方法(例えば非特許文献1)、〈2〉絹フィブロインを酢酸パラジウムのメタノール溶液に室温下4日間静置する方法(例えば非特許文献2、非特許文献3)等が知られている。しかしながら、〈1〉の方法では、得られた触媒の一部を切り取って反応に使用した場合、切り取る箇所によって触媒活性に差が出てしまい反応の再現性に悪影響を及ぼしてしまう等の問題点があり、〈2〉の方法は、調製に4日間もの時間を要することから、工業的生産には有利なものではなかった。 For example, <1> a method of preparing a catalyst in which palladium is adsorbed on silk under high temperature, high pressure, and strong acidic conditions (for example, non-patented) Literature 1), <2> A method in which silk fibroin is allowed to stand in a methanol solution of palladium acetate for 4 days at room temperature (for example, Non-Patent Literature 2 and Non-Patent Literature 3) is known. However, in the method <1>, when a part of the obtained catalyst is cut out and used for the reaction, there is a problem in that the catalytic activity varies depending on the portion to be cut out and adversely affects the reproducibility of the reaction. The method <2> is not advantageous for industrial production because it takes 4 days to prepare.
そのため、繊維状タンパク質に担持させた金属触媒(以下、繊維状タンパク質担持金属触媒と略記する場合がある。)のどの部分を切り取って使用してもほぼ同等の触媒活性を有し、また、短時間で調製が可能で工業的生産に適した、繊維状タンパク質への金属触媒の担持方法の開発が望まれていた。 Therefore, any portion of a metal catalyst supported on a fibrous protein (hereinafter sometimes abbreviated as “fibrous protein-supported metal catalyst”) has almost the same catalytic activity even if it is cut out and used. It has been desired to develop a method for supporting a metal catalyst on a fibrous protein that can be prepared in time and is suitable for industrial production.
本発明は、工業的生産に適した繊維状タンパク質への金属触媒の担持方法を提供することにある。さらに詳しくは、得られる繊維状タンパク質担持金属触媒のどの部分を切り取って使用しても、その触媒活性がほぼ同等で、なおかつ、短時間で調製が可能な、繊維状タンパク質への金属触媒の担持方法を提供することにある。 It is an object of the present invention to provide a method for supporting a metal catalyst on a fibrous protein suitable for industrial production. More specifically, no matter what part of the resulting fibrous protein-supported metal catalyst is cut out, the catalytic activity is almost the same, and the metal catalyst can be supported on the fibrous protein that can be prepared in a short time. It is to provide a method.
本発明は、金属触媒化合物と繊維状タンパク質とを、水、金属触媒化合物を還元し得る有機溶媒、これらの混合液又は還元剤を含む溶媒中で、超音波照射下に接触させることを特徴とする、繊維状タンパク質への金属触媒の担持方法である。 The present invention is characterized in that the metal catalyst compound and the fibrous protein are brought into contact with each other under ultrasonic irradiation in water, an organic solvent capable of reducing the metal catalyst compound, a mixture thereof, or a solvent containing a reducing agent. This is a method for supporting a metal catalyst on a fibrous protein.
本発明の担持方法によれば、従来の担持方法で得られたものと同程度の活性を有する繊維状タンパク質担持金属触媒を、短時間で調製することが可能となる。 According to the supporting method of the present invention, it is possible to prepare a fibrous protein-supported metal catalyst having an activity comparable to that obtained by the conventional supporting method in a short time.
本発明に於ける繊維状タンパク質としては、具体的には、例えば絹糸、絹フィブロイン、羊毛等が挙げられ、中でも絹糸、絹フィブロインが好ましく、その中でも絹フィブロインがより好ましい。 Specific examples of the fibrous protein in the present invention include silk thread, silk fibroin and wool, among which silk thread and silk fibroin are preferable, and silk fibroin is more preferable.
尚、絹フィブロインとは、カイコ(Bombyx mori)に代表される絹糸虫から合成される繭の主要な繊維状タンパク質を意味する。当該絹フィブロインは、繊維業者から購入することも可能であるが、例えばカイコから得られた繭を炭酸ナトリウム、亜ジチオン酸ナトリウム及びエチレンジアミン四酢酸二カリウム塩(EDTA dipotassium salt dihydrate)を含む水溶液中で煮沸し、次いで水洗、乾燥することにより調製することができる。 Silk fibroin means the main fibrous protein of cocoons synthesized from silkworms represented by silkworm (Bombyx mori). The silk fibroin can be purchased from a textile company. For example, silkworms obtained from silkworms in an aqueous solution containing sodium carbonate, sodium dithionite and dipotassium salt of ethylenediaminetetraacetate (EDTA dipotassium salt dihydrate). It can be prepared by boiling, then washing with water and drying.
