- the reducing agent used at this time include a reducing agent selected from the group consisting of hydrogen, carbon monoxide, aldehydes, carboxylic acids, amines, metal hydrides, and hydrazine.
- the method of reducing the catalyst fine particles in advance using the reducing agent is insufficient from the viewpoint of aggregation of the catalyst fine particles.
- the catalyst fine particles are reduced not by a reducing agent but by a phenolic hydroxyl group, and a resin-supported catalyst having excellent repeatability and utilization efficiency can be manufactured.
- aggregation of catalyst fine particles can be prevented by reducing the catalyst fine particles using a phenolic hydroxyl group. That is, when the catalyst fine particles are reduced by the phenolic hydroxyl group, the catalyst fine particles can be uniformly supported on the surface of the cured body of the thermosetting resin that is the catalyst carrier. For this reason, it leads to the improvement of reaction efficiency, and the resin carrying catalyst excellent in the repetition characteristic and utilization efficiency can be manufactured.

- the catalyst fine particles can be reduced on the surface of the thermosetting resin having a phenolic hydroxyl group. Therefore, the catalyst fine particles can be uniformly and finely supported on the surface of the cured body of the thermosetting resin. Therefore, it is possible to obtain a resin-supported catalyst having excellent repeatability and utilization efficiency.
- the reducing agent is most preferably not contained in the catalyst-supported reaction solution. By doing so, aggregation of the supported catalyst fine particles is less likely to occur compared to the resin-supported catalyst obtained by the conventional method. For this reason, the resin-supported catalyst obtained by the method according to the present embodiment is remarkably superior in the repeatability and utilization efficiency of the resin-supported catalyst compared to the resin-supported catalyst obtained by the conventional method.
- the reducing agent molecules that inhibit the dispersion of the catalyst fine particles are contained in the catalyst-supported reaction solution when reducing the catalyst fine particles. Therefore, it is considered that the catalyst fine particles are uniformly and finely dispersed on the surface of the cured body of the thermosetting resin. For this reason, it is considered that the resin-supported catalyst according to the present embodiment supports the catalyst fine particles more firmly on the surface of the cured body of the thermosetting resin than the conventional resin-supported catalyst.
- the catalyst fine particles are reduced in advance using a reducing agent.
- reducing agent used herein include aldehydes such as hydrogen, carbon monoxide and formaldehyde, carboxylic acids such as formic acid and oxalic acid, amines such as triethylamine, sodium borohydride and lithium aluminum hydride. Metal hydrides and hydrazine are mentioned.
- the catalyst fine particles are reduced using a reducing agent as in the conventional method for producing a resin-supported catalyst
- the catalyst fine particles are supported on the catalyst carrier in the procedure described below.
- the catalyst fine particles are reduced in advance using a reducing agent.
- the catalyst fine particles reduced and precipitated by the reducing agent are supported on the catalyst carrier. That is, in the conventional method for producing a resin-supported catalyst, catalyst fine particles are reduced, and the precipitated catalyst fine particles are dispersed in a solution, and then the catalyst fine particles are supported on the catalyst carrier.
- catalyst fine particles are reduced by a phenolic hydroxyl group. Specifically, the catalyst fine particles are reduced on the surface of the thermosetting resin having a phenolic hydroxyl group. That is, in the method for producing a resin-supported catalyst according to the present embodiment, the catalyst fine particles are brought into contact with a cured body of a thermosetting resin that is a catalyst carrier, and then the catalyst fine particles are reduced and precipitated. According to this method for producing a resin-supported catalyst, the catalyst fine particles can be uniformly and finely supported on the catalyst carrier. By doing so, it is possible to produce a resin-supported catalyst having excellent repeatability and utilization efficiency.
- the reason for this is not necessarily clear, but it is thought that the precipitation of the reduced catalyst fine particles and the loading of the precipitated catalyst fine particles on the catalyst carrier occur almost simultaneously. That is, compared with the conventional method for producing a resin-supported catalyst, the catalyst fine particles can be supported on the catalyst carrier without dispersing the precipitated catalyst fine particles in the solvent, and therefore the aggregation of the catalyst fine particles can be highly suppressed. Conceivable.
- the catalyst fine particles are reduced with phenolic hydroxyl groups in the liquid phase and supported on a catalyst carrier having phenolic hydroxyl groups.
- a catalyst carrier having phenolic hydroxyl groups When reducing the catalyst fine particles with the phenolic hydroxyl group, it is preferable not to add the reducing agent. By doing so, the catalyst fine particles can be reduced on the surface of the thermosetting resin having a phenolic hydroxyl group. Therefore, the catalyst fine particles can be uniformly and finely supported on the surface of the cured body of the thermosetting resin.
- the first implementation is performed as a method for forming a cured body of a thermosetting resin, catalyst fine particles, a substrate-supported catalyst, a substrate, and a cured body of a thermosetting resin on the surface of the substrate.
- the first implementation is performed as a method for forming a cured body of a thermosetting resin. The same thing as what is described in a form can be used.

Abstract
Description
熱硬化性樹脂の硬化体と、
前記硬化体の表面に担持された触媒活性を有する微粒子と、
を含み、
前記熱硬化性樹脂がフェノール性水酸基を有する樹脂担持触媒が提供される。
前記硬化工程において得られた硬化体の表面に触媒活性を有する微粒子を担持させる担持工程と、
を含む樹脂担持触媒の製造方法が提供される。
本実施形態における樹脂担持触媒は、触媒微粒子が熱硬化性樹脂の硬化体の表面に担持されているため、反応物が触媒微粒子に到達しやすい。そのため、触媒の利用効率が優れている。
また、本実施形態における樹脂担持触媒は触媒の繰り返し特性に優れている。その理由は必ずしも明らかではないが、以下のように考えられる。本実施形態における樹脂担持触媒では、担体として表面にフェノール性水酸基を有する熱硬化性樹脂の硬化体が用いられている。そして、触媒担体に存在するフェノール性水酸基により担持されているものと考えられる。こうすることにより、触媒微粒子は、従来の担持触媒と比較して、強固に担持されているものと考えられる。したがって、触媒担体である熱硬化性樹脂の硬化体から、触媒微粒子が脱離しにくくなり、触媒の繰り返し特性と利用効率が向上したものと考えられる。
熱硬化性樹脂の硬化体は、本実施形態において触媒担体として用いられる。熱硬化性樹脂の硬化体は、例えば、粒子状、膜状、均一な層状に形成していてもよい。硬化処理前の熱硬化性樹脂としては、フェノール性水酸基を有する熱硬化性樹脂であればとくに限定されないが、フェノール樹脂またはその誘導体を含むことが好ましい。
例えば、フェノール樹脂、クレゾール樹脂、レゾルシン樹脂、キシレノール樹脂、ナフトール樹脂、ビスフェノールA樹脂、アラルキルフェノール樹脂、ビフェニルアラルキルフェノール樹脂、およびフェノール性水酸基を有するカシューナッツ油などによる変性フェノール樹脂などが挙げられる。また、フェノール性水酸基を有する物質を含む、キシレン変性フェノール樹脂、およびフェノール類とロジン、テルペン油などで変性した油変性フェノール樹脂、ゴムで変性したゴム変性フェノール樹脂などの各種変性フェノール樹脂なども使用することができる。
本実施形態における熱硬化性樹脂の硬化体の表面に担持される触媒微粒子としては、触媒活性を有するものであれば金属、金属酸化物および金属化合物のいずれであってもよく、とくに限定されるものではない。例えばチタン、クロム、コバルト、ニッケル、銅、ルテニウム、ロジウム、パラジウム、レニウム、オスミニウム、白金、鉄、亜鉛、マンガン、マグネシウム、カルシウム、銀、バナジウム、スズなどの金属ならびにその酸化物、その他の有機チタンなどの金属化合物および錯体などの中から選ばれる少なくとも1種からなるものが挙げられる。また、これらのうちの少なくとも二種類以上を含む複合体も使用することもできる。これらの中でも、とくにパラジウムまたは白金が好適に用いられる。
本実施形態における熱硬化性樹脂の硬化処理方法としてはとくに限定されないが、公知の方法を採用することができる。
本実施形態における熱硬化性樹脂の硬化体への上記触媒微粒子の担持方法について詳細に説明する。本実施形態においては、熱硬化性樹脂の硬化体を作製後、その硬化体の表面に触媒微粒子を担持させることが好ましい。こうすることで、触媒微粒子が硬化体の内部に取り込まれるのを抑制することができる。
本実施形態に係る基材担持触媒は、シート状あるいは板状であることで、反応装置の形状に合わせて、種々の形状に変形させることが可能である。触媒シートの形状は、例えば、折りたたまれた状態、丸めた状態など反応装置における反応管の形状に合わせて種々の形状に変形させることができる。シート状の樹脂担持触媒において連通孔が設けられている場合、触媒フィルターとして用いることも可能である。
次に、基材の形状は、特に限定されるものではないが、例えば、粒子状、シート状あるいは板状が用いられる。これらの中でも、シート状あるいは板状であることが好ましい。
本実施形態において熱硬化性樹脂の硬化体を基材の表面に形成する方法は、基材の形状によって、適宜方法を選択することができる。例えば、基材がメッシュ状である場合、固形や粉末の樹脂の溶液や液状樹脂を基材に含浸硬化する方法、固形や粉末の樹脂を加熱溶融して基材に含浸硬化する方法、等が用いられる。これに対し、基材が粒子状である場合、熱硬化性樹脂の硬化体をコーティングする方法、等が用いられる。こうすることで、基材に均一に熱硬化性樹脂の硬化体を形成することが可能である。
第1の実施形態において用いられている触媒微粒子の具体的な製造方法に関する。
しかしながら、還元剤を用いて事前に触媒微粒子を還元する方法は、触媒微粒子の凝集という観点では、不十分であった。
上述したように従来の樹脂担持触媒の製造方法では、還元剤を用いて事前に触媒微粒子を還元している。ここで用いている還元剤としては、例えば、水素、一酸化炭素、ホルムアルデヒドなどのアルデヒド類、ギ酸やシュウ酸などのカルボン酸類、トリエチルアミンなどのアミン類、水素化ホウ素ナトリウムや水素化アルミニウムリチウムなどの金属ヒドリド、およびヒドラジンが挙げられる。

酢酸パラジウム(和光純薬工業社製)10mgと、実施例B1と同様に作製したフェノール樹脂担体1gと、トリエチルアミン(和光純薬工業社製,酢酸パラジウムに対して50mol)0.3mLと、アセトニトリル(和光純薬工業社製)10mLを配合し、封管中、100℃で12時間加熱した。つづいて、フェノール樹脂担体をピンセットで取り出した後、洗浄し乾燥することで、パラジウム粒子が担持されたフェノール樹脂担持触媒を得た。フェノール樹脂担持触媒中におけるパラジウム触媒の担持量は1重量%であった。
担持触媒の触媒活性は、ヨードベンゼンと、アクリル酸メチルとのヘック反応で得られるトランス-桂皮酸メチルの反応収率により評価した。
ヨードベンゼン230μL(2.0mmol)、アクリル酸メチル230μL(2.5mmol)、トリエチルアミン350μL(2.5mmol)をアセトニトリル(20mL)に溶解した。得られた溶液に担持触媒を500mg加えた。混合物をオイルバスを用いて加熱し、120℃で12時間攪拌した。反応終了後、担持触媒をピンセットによって取り出すか、あるいは濾別することによって回収した。
反応終了後、反応液から担持触媒を回収し、洗浄した。その後、回収した担持触媒を用いて上記のヘック反応をおこなった。これらのヘック反応の一連の操作を、トランス-桂皮酸メチルの反応収率が80%を下回るまで繰り返した。その結果を下記表2に示す。
