Description
<1>本発明の二酸化炭素の酢酸への変換方法は、酸化マンガンの存在下、マンガンイオン、クロムイオンおよびコバルトイオンからなる群より選ばれる少なくとも一種の金属イオンを含む水溶液に二酸化炭素および酸素を接触させて二酸化炭素を酢酸に変換する。
<2>上記第1の発明において、酸化マンガンは、層状酸化マンガンまたはその酸処理物である。
<3>上記第1または第2の発明において、炭酸マンガンを酸水溶液に溶解して酸化マンガンと二酸化炭素を生成させ、得られたマンガンイオンを含む水溶液に酸素を接触させて二酸化炭素を酢酸に変換する。
<4>本発明の二酸化炭素から酢酸に変換するための触媒は、炭酸マンガンを酸水溶液で溶解してなる。
<5>上記第4の発明において、炭酸マンガンを酸水溶液に溶解することによって生成された酸化マンガンを含有し、該酸化マンガンが層状酸化マンガンである。
ビーカー中の0.5mol/L希塩酸(HCl)500mL(水温20℃)に、12.5gの炭酸マンガンMnCO3・nH2O(和光純薬製試薬特級)を加えて1時間、マグネチックスタラーで攪拌した。60分経過後にビーカー中の物質を0.2マイクロ・メッシュのガラスろ紙(アドバンテック(株)GS−25)と減圧ろ過器を使ってガラスろ紙上に回収した。ろし上に回収された物質を500mLの超純水に懸濁させて1時間、テフロン(登録商標)製のマグネチックスタラーで攪拌した後、再び同様にろ過回収し、粉末X線回折分析装置(リガク製RINT−2000、CuKα)でその結晶構造を分析した。分析結果を図1に示した。同パターンから同物質が層状酸化マンガンの結晶構造を有している事が同定できた。特に最も低角側の2θが12.1°にピークがあることが特徴的である。一般的に層状酸化マンガンは、酸化マンガン層の層間に入る物質によって、最低角ピークが移動する事が知られている。本材料に関する図1に示した結果では水素イオンH+や塩素イオンCl−などが酸化マンガン層の層間に入り込んで層状酸化マンガンが構成されているものと考えられた。
<実施例2>二酸化炭素の酢酸への変換反応
実施例1の実験において、炭酸マンガンを希塩酸に添加後5分、および60分経過時に、合成実験中の希塩酸水溶液のサンプルをガラスろ紙(アドバンテック(株)のテフロン(登録商標)樹脂製のDISMIC)を用いて15mLずつ採取した。採取した各サンプルを島津製作所製の有機酸分析装置を用いてサンプルに含まれる有機酸濃度を分析した。その結果、5分および60分のサンプルには酢酸が105ppmの濃度で含まれていることがわかった。これに対してギ酸の濃度は両サンプルとも0.2ppmと極めて低く、酢酸が優位に発生していることが分かった。通常、炭酸マンガンは、希塩酸水溶液中でマンガンイオンと塩素イオン、および二酸化炭素と水を発生しながら溶解するが、もともと酢酸は含まない。このため、実施例1で記載した合成実験の際に同希塩酸中で発生した層状酸化マンガンおよびマンガンイオンらが触媒として働くことで二酸化炭素を酢酸に変換したものと考えられた。変換効率は、炭酸マンガンから発生する二酸化炭素分子が約700個に1個の割合で酢酸分子に変換されていると計算できた。また、炭酸マンガンの希塩酸中での溶解反応は二酸化炭素が発泡しながら発生するため空気中から酸素を含んだ大気が同希塩酸中に混入するため、酢酸への変換反応に必要なアセトアルデヒトの空気酸化反応が一気に進んだものと考えられた。このため、添加後5分のサンプルと60分のサンプルには、ほぼ同濃度の酢酸濃度が検出されたものと考えられた。同様な酢酸発生の結果は、希塩酸の代わりに0.25mol/Lの希硫酸(H2SO4)を用いた場合にも確認された。
