Definitions
- the present invention relates to a method for producing a modified aluminosilicate, a method for producing a modified aluminosilicate, and an aromatic polyhydroxide compound using the same.
- Aromatic dihydroxide compounds are important as various organic synthesis intermediates or raw materials, and are used in fields such as reducing agents, rubber chemicals, dyes, pharmaceuticals, agricultural chemicals, polymerization inhibitors, and oxidation inhibitors.
- Aromatic dihydroxide compounds obtained by reacting phenols with hydrogen peroxide are, for example, hydroquinone and catechol, and the production ratio of hydroquinone and catechol varies depending on the manufacturing method. In recent years, from the balance of demand for hydroquinone and catechol, a method for producing hydroquinone with high selectivity has been desired.
- Patent Document 1 A method of using titanosilicate, which is one of crystalline porous silicates, as a catalyst for producing an aromatic dihydroxide compound by reacting a phenol with hydrogen peroxide has been disclosed (for example, Patent Document 1 , Patent Document 2). Further, Patent Document 3 discloses a titanosilicate obtained by treating acid-treated aluminosilicate with vapor phase titanium chloride or titanium alkoxide.
- a gel is prepared by mixing with an aluminosilicate mold raw material, an aluminum source, a titanium source, a silicon source, an iodide, and water, which is then heated to crystallize and then fired.

Crystalline porous aluminosilicates are preferred, and UZM-35, MCM-68, YNU-3 and the like are particularly preferred.
- the crystalline porous aluminosilicate having the MSE skeleton has a three-dimensional pore structure having a 10-membered ring structure consisting of 10 tetrahedral units and a 12-membered ring structure consisting of 12 tetrahedral units.
- the crystal (A) is produced by contacting a known silicon source such as known colloidal silica, an aluminum source such as zeolite, and preferably an organic structure directing agent such as dimethyldipropylammonium hydroxide or a known alkali source. and stirring and heating.

<アルミノシリケート(A-1’)を用いた変性アルミノシリケートの製造方法>
本発明の変性アルミノシリケートの製造方法は、ゲル状のシリカと、ゼオライトと
XRD測定で17.5~35°領域で、22.5~25.0°に最も高いピーク(α)を有するアルミノシリケートである結晶(A)(以下、単に「結晶(A)とも称す」とを接触させてアルミノシリケート(A-1’)を得る第1工程と、
前記第1工程で得られるアルミノシリケート(A-1’)を酸と接触させる第2工程と、
前記第2工程で得られた処理物を550℃~850℃で一次焼成する第3工程と、
前記第3工程で得られた焼成物と、周期表の4族元素及び5族元素からなる群より選ばれる1つ以上の元素を含む液体とを接触させた後、乾燥及び二次焼成を行う第4工程とを含む。
第1工程は、結晶(A)とケイ素源であるゲル状のシリカと、アルミニウム源であるゼオライトとを接触させてアルミノシリケート(A-1’)を製造する工程である。
前記、第1工程で得られたアルミノシリケート(A-1’)を酸で処理する工程、換言するとアルミノシリケート(A-1’)を酸と接触させる工程が第2工程である。
この工程で使用する酸としては、例えば、無機酸、有機酸及びこれらの混合物が挙げられ、これらの具体例としては、例えば、硝酸、塩酸、硫酸、クエン酸、シュウ酸及びこれらの混合物が挙げられる。これらの中でも、周期表の15族、16族元素から選ばれる元素を含む酸が好ましく、特には硝酸が好ましい。酸の濃度は特に制限されないが、5重量%~80重量%が好ましく、40重量%~80重量%がより好ましい。この酸を水溶液として用いる場合、その使用量は、アルミノシリケート(A-1’)1重量部に対して、1~100重量部であることが好ましい。より好ましい下限値は2重量部であり、さらに好ましくは3重量部であり、特に好ましくは5重量部である。その上に好ましい前記下限値は。10重量部であり、より好ましくは20重量部である。一方、より好ましい上限値は70重量部、さらに好ましくは50重量部である。
第3工程では、上記第2工程で得られた処理物、即ち酸と接触させたアルミノシリケート(A-1’)の一次焼成を行う。焼成する方法としては、特に制限はなく、例えば、電気炉、ガス炉等を使用して焼成する方法が挙げられる。焼成条件としては、大気雰囲気中で、0.1時間~20時間加熱することが好ましい。焼成温度は550℃~850℃であり、600℃~800℃がより好ましい。この比較的高温環境下での一次焼成によって、活性の高い状態で、チタン種を代表例とする周期表の4族元素、5族元素が含まれる、第4工程で得られる所謂変性アルミノシリケート形成に有利な環境が得られるものと推測される。
第4工程では、上記第3工程で得られた焼成物(以下、「一次焼成物」とも称す)と、周期表の4族元素及び5族元素から選ばれる1つ以上の元素を含む液体を、元素源として液相状態で接触させ、その後に乾燥及び二次焼成を行う。前記の周期表の4族元素及び5族元素としては、チタン、ジルコニウム、ハフニウム、バナジウム等を挙げることが出来る。好ましい元素は、チタン、ジルコニウム、バナジウムであり、特にチタンが好ましい。これらの元素を含む化合物としては、各元素のハロゲン化物、アルコキシドや無機酸の塩を好適な化合物として挙げることが出来る。より好ましくはハロゲン化物としては塩化物、アルコキシドとしては、炭素数1~6のアルコキシ基を含む態様である。さらに好ましいアルコキシドとしては、エトキシド、ブトキシド(n-ブトキシド、i-ブトキシド、s-ブトキシド、t-ブトキシド)、硫酸塩等を挙げることが出来る。これらの化合物は、2種以上を併用してももちろん構わない。
上記の製造条件は、チタン以外の元素を用いる場合についても準用することができる。
第4工程で得られる変性アルミノシリケートは、第1工程で得られるアルミノシリケート(A-1’)と同様、結晶性および多孔質性を有する結晶性多孔質アルミノシリケートが好ましく、MSE骨格を有する結晶性多孔質アルミノシリケートがより好ましく、UZM-35、MCM-68、YNU-3構造を有する結晶性多孔質アルミノシリケートがさらに好ましく、結晶性多孔質アルミノチタノシリケートが特に好ましい。結晶性とは、結晶(A)の説明と同様の態様と考えて差し支えない。
本発明の一実施形態は、XRD測定で17.5~35°の領域で、20°以上22.5°未満の領域に最も高いピーク(β)を有し、該ピーク(β)の25~27°の領域の最も高いピーク(γ)に対するピーク強度比が1.7~5.0の範囲であるアルミノシリケート(A-1)である。前記ピーク強度比の好ましい下限値は1.72であり、よりこのましくは1.8であり、特に好ましくは1.9である。一方、好ましい上限値は4.5であり、より好ましくは4.2であり、さらに好ましくは4.0であり、特に好ましくは3.5である、この中でも、さらに好ましくは3.0であり、特に好ましくは2.5である。
本発明の一実施形態は、アルミノシリケート(A-1)を酸で処理する第2工程と、前記第2工程で得られた処理物を550℃~850℃で一次焼成する第3工程と、前記第3工程で得られた焼成物と、周期表の4族元素及び5族元素からなる群より選ばれる1つ以上の元素を含む液体とを接触させた後、乾燥及び二次焼成を行う第4工程とを含む、変性アルミノシリケートの製造方法である。
