Description
(1)含水湿潤ゲルの乾燥方法であって、まず該含水湿潤ゲルから水を除去して含水湿潤ゲルの水含有量を減少させ、次いで、残余の溶媒を除去することにより湿潤ゲルを乾燥することを特徴とする含水湿潤ゲルの乾燥方法。
前記したように、含水湿潤ゲルを乾燥する際に乾燥ゲルに亀裂が発生する原因の一つは、乾燥時に湿潤ゲル中の細孔が収縮することである。この原因となるのは、湿潤ゲルの細孔に働く溶媒の表面張力である。水は表面張力が他の汎用の溶媒に比べ大きく、また、沸点も高いため、乾燥が進行すると他の溶媒が蒸発した後細孔に水が残り、細孔に大きな表面張力が働いて、孔の収縮を引き起こす。したがって、本発明者らは、含水湿潤ゲルの乾燥時の収縮を抑制するためには、まず含水湿潤ゲルから表面張力の大きな溶媒である水をできるだけ取り除き、次いで、残りの溶媒を乾燥させればよいという従来考えられていなかった考えに至った。このような方法によれば、ゲルの種類を問うことなく、いずれのゲルであっても乾燥時に亀裂の発生なく含水ゲルの乾燥が行える。
テトラエトキシシラン5.21gに、エタノール4.61gおよび硝酸0.032gを含む水4.50gを添加して20℃で10分間攪拌して均一な透明溶液を得た。この溶液の入った容器1を密封し、80℃で2日間静置してゲル化とゲルの熟成を行った。300℃の乾燥空気中で3時間以上乾燥させたモレキュラーシーブ3A 約27gを容器2に詰め、湿潤ゲルの入った容器1と連結して80℃でさらに1日間静置し、湿潤ゲルに含まれる溶媒の脱水を行った。続いて、モレキュラーシーブ3Aの入った容器2を取り外して湿潤ゲルの入った容器を開封し、80℃で乾燥を行ったところ、3日間で乾燥が終了し、亀裂のない乾燥ゲルが得られた。得られた乾燥ゲルを空気中、300℃で熱処理して有機成分を除去した後、窒素吸着測定を行ったところ、全細孔容積、BET比表面積、および両者の値から円筒状細孔を仮定して計算した平均細孔直径は、それぞれ0.53cm3g-1、946m2g-1、2.3nmであった。
テトラエトキシシラン5.21gに、エタノール4.61gおよび硝酸0.032gを含む水4.50gを添加して20℃で10分間攪拌して均一な透明溶液を得た。この溶液の入った容器1を密封し、80℃で2日間静置してゲル化とゲルの熟成を行った。この容器を密封したまま、この湿潤ゲルに含まれる溶媒の脱水を行わずに80℃でさらに1日間静置し、続いて湿潤ゲルの入った容器を開封して80℃で乾燥を行ったところ、4日間で乾燥が終了し、亀裂が数本入った乾燥ゲルが得られた。得られた乾燥ゲルを空気中、300℃で熱処理して有機成分を除去した後、窒素吸着測定を行ったところ、全細孔容積、BET比表面積、および両者の値から円筒状細孔を仮定して計算した平均細孔直径は、それぞれ0.45cm3g-1、808m2g-1、2.2nmであり、実施例1で得られた乾燥ゲルと比較して大きな違いはなかった。
テトラエトキシシラン5.21gに、2−プロパノール4.51gおよびフッ化水素0.051g含む水4.51gを添加して20℃で5分間攪拌し、均一な透明溶液を得た。この溶液の入った容器1を密封して20℃で静置したところ、約25分でゲル化した。この湿潤ゲルの入った容器をモレキュラーシーブ3Aが約27gの入った容器2と連結して60℃で2日間静置し、湿潤ゲルに含まれる溶媒の脱水を行った。続いて、モレキュラーシーブ3Aの入った容器2を取り外して湿潤ゲルの入った容器1を開封し、60℃で乾燥を行ったところ、2日間で乾燥が終了し、亀裂のない乾燥ゲルが得られた。得られた乾燥ゲルを空気中、300℃で熱処理して有機成分を除去した後、窒素吸着測定を行ったところ、全細孔容積、BET比表面積、および両者の値から円筒状細孔を仮定して計算した平均細孔直径は、それぞれ1.52cm3g-1、506m2g-1、12nmであった。
