Description
[式中、Mは、ロジウム、白金、イリジウム又はパラジウムからなる群から選択される金属であり、
アルキルは、炭素原子を最大で6個有するアルキル基であり、
Yは、1、2、又は3であり、
Xは4又は6である]。
容量5Lの反応器に758gの脱塩水を入れ、白金1モルあたり約2モルに相当する濃度35重量%の1.47kgのテトラエチルアンモニウムヒドロキシド水溶液を加えた。
13.5gのロジウムヒドロキシド(RhOH3)を10gの水に懸濁し、濃度35重量%の61.594gのテトラエチルアンモニウムヒドロキシド水溶液を1ショット添加し、22℃の温度で1時間撹拌した。約30分後に褐色の溶液が得られた。これをG4のガラスフリットを通してろ過し、分析した。
水酸化物の製造
濃度35重量%のテトラエチルアンモニウムヒドロキシド水溶液866gを準備し、pH値が3.6〜3.7になるまで、30分かけて、パラジウム含有量130gの約540gの硝酸パラジウム溶液を滴下した。溶液の正確な量はパラジウムの含有量によって異なり、それに応じて変更することができる。添加中に反応熱が生じ、40℃にまで加熱された。
次に、濃度35重量%の1.0モル当量のテトラエチルアンモニウムヒドロキシド溶液を準備し、これに乾燥させておいた濾液を添加し、23℃の温度で1時間撹拌した。続いて、G4ガラスフリット上でろ過し、乾燥させた。
実施例1と同様の手順であるが、下記のとおりに変更を加えた。テトラプロピルアンモニウムヒドロキシド(40重量%)の水溶液を使用し31.92重量%のヘキサヒドロキシ白金酸の水溶液を準備し、20℃〜25℃にて180分間撹拌した後、50℃に加温した。更に5mLのテトラプロピルアンモニウムヒドロキシ℃溶液を加え、終夜放置し(約18時間)、G4のガラスフリットでろ過し、15分間遠心した。このようにして得られた清澄なテトラプロピルアンモニウムヘキサヒドロキシプラチネート溶液の白金含有量は9.08%であった。
手順は、実施例4と同様の手順としたが、下記のとおりに変更を加えた。凍結させたテトラブチルアンモニウムヒドロキシド*30H2Oを使用し、39.3重量%のヘキサヒドロキシ白金酸を含有する水溶液を準備し、20℃〜25℃で終夜(約18時間)撹拌した後、15分間遠心した。このようにして得られた清澄なテトラブチルアンモニウムヘキサヒドロキシプラチネート溶液は暗黄色を示した。
45gの酸化アルミニウムと、16gのゼオライト(TosohのZeolite−HSZ−0940NHA)を水に懸濁し、15分間攪拌した。次に、テトラエチルアンモニウムヒドロキシドを添加して、pH値を10に調整した後、可溶性白金化合物の形態で溶解させた白金0.81gを添加し、15分間撹拌した。次に、硝酸パラジウムの形態のパラジウム0.54gを水に添加し、再度15分間撹拌した。次に、pH値を酢酸で5に調整した後、5分間攪拌した。次に、水中に残存する貴金属含有量を測定した。
