本発明の製造方法において、前記混合物、或いは、前記多価アルコール誘導体変性シリコーン又はその組成物(以下、単に「多価アルコール誘導体変性シリコーン又はその組成物」という)は、酸性物質によって処理され、当該酸性物質の処理によって発生した臭気物質及び低沸点成分が加熱又は減圧により取り除かることが好ましい。この場合は、より高品質の多価アルコール誘導体変性シリコーン又はその組成物を得ることができる。前記処理は非極性溶媒及び/又は極性溶媒及び/又は水の存在下で実施することが可能であるが、酸性物質は、水等の極性溶媒に溶解あるいは分散させて使用することが好ましく、酸性水溶液を含む形態で前記処理に供するのがより好ましい。また、既述のとおり、酸処理工程は本発明の高純度化処理の前に行うと、より優れた高純度化が達成されるため、好ましい。製造プロセスの合理性とコスト、得られる効果等を総合的に考慮すると、「多価アルコール誘導体変性シリコーンの合成」→「酸処理と臭気低減」→「高純度化処理」の順でステップを踏むのが最善である。但し、合成工程がヒドロシリル化反応以外の場合など酸処理の必要性が低い場合には、酸処理工程をスキップすることができる。そして、前述した「液状油剤添加工程」は、この3つの基本ステップの前後どのタイミングで実施してもよい。

次いで、前記実施例4と同様の手法でこの濾液からトルエンを留去することにより、平均組成式:MD43.4DR*11 5。3DR*22 2DR*32 0.1Mで表される、液状の高純度多価アルコール誘導体変性シリコーンNo.4を淡黄色ほぼ透明均一な粘稠液体として得た。(収量142g) 式中、R*11、R*22及びR*32は前記のとおりである。
<液状の高純度多価アルコール誘導体変性シリコーンNo.4の調製>
反応器に製造例4で得られた灰褐色不透明粘稠液体(多価アルコール誘導体変性シリコーンNo.4を主成分として含む組成物)150g、トルエン 150g、クエン酸3Na二水和物(無色粒状結晶)4.5gを仕込み、50-65℃に加温して40分間攪拌混合したのち、室温まで放冷した。
前記実施例4の場合と同様に、加圧濾過器、目皿、濾紙、受け器をセットし、同様の手法により主として中間粒度10.9μmの珪藻土微粉末5gからなる濾層を形成、及び前記処理で得られた濁液状混合物をこの濾層に通すことにより、淡褐色透明均一な濾液を得た。
次いで、前記実施例4と同様の手法でこの濾液からトルエンを留去することにより、平均組成式:MD43.4DR*11 5。3DR*22 2DR*32 0.1Mで表される、液状の高純度多価アルコール誘導体変性シリコーンNo.4を淡黄色ほぼ透明均一な粘稠液体として得た。(収量140g) 式中、R*11、R*22及びR*32は前記のとおりである。
この後、乾燥した珪藻土の濾層上を観察したところ、使用前にはおよそ0.5mm四方の結晶状であったクエン酸3Naが凝集して直径数mm程度の大きな塊状となり残っているのが分かった。このことから、濁り原因物質である親水性不純物(この場合は主としてジグリセリン)が、クエン酸3Naと一体化して分離されたものと思われる。
<液状の高純度多価アルコール誘導体変性シリコーンNo.5を含む組成物の調製>
製造例5で得られた白色の不透明液体{多価アルコール誘導体変性シリコーンNo.5を主成分として含む組成物と、カプリリルメチコン(希釈剤)とからなる組成物}を126g、中間粒度10.9μmの珪藻土微粉末1.23gをカップに仕込み、スパチュラでよくかき混ぜてスラリー状とした。
前記実施例1の場合と同様に(但し、ここでは加圧ろ過器と濾紙の内径あるいは直径が95mmの小型タイプに変更し)、加圧濾過器、目皿、濾紙、受け器をセットしたのち、前述のスラリー全量を加圧濾過器にセットした濾紙上に注ぎ、濾過器に蓋をして上部より窒素圧0.3MPaをかけることにより、主として中間粒度10.9μmの珪藻土微粉末からなる濾層を形成した。次いで、濾層形成時に回収した濾液を再度前記濾層上に注ぎ、同様にして通過させることにより、「以下の平均的構造式(模式図)に示される液状の高純度多価アルコール誘導体変性シリコーンNo.5と、カプリリルメチコン(希釈剤)とからなる組成物」{上記シリコーンNo.5:希釈剤の重量(質量)比は1:1}を、かなり透明~半透明な均一液体として得た。(収量112g)
<液状の高純度多価アルコール誘導体変性シリコーンNo.6を含む組成物の調製>
反応器に製造例6で得られた乳白色均一なガム状流体{多価アルコール誘導体変性シリコーンNo.6を主成分として含む組成物と、カプリリルメチコン(希釈剤)とからなる組成物} 130g、トルエン 142g、カルボキシビニルポリマー(別名:カルボマー、白色微粉末) 2.0gを仕込み、65-80℃に加温して40分間攪拌混合したのち、室温まで放冷した。
前記実施例5の場合と同様に、加圧濾過器、目皿、濾紙、受け器をセットした。
前述の処理で得られた濁り液100gをカップに取り、これに中間粒度10.9μmの珪藻土微粉末3gを加え、ヘラでよくかき混ぜてスラリー状とした。このスラリーを、加圧濾過器にセットした濾紙上に注いだ後、濾過器に蓋をして上部より窒素圧0.1~0.2MPaをかけることにより、主として中間粒度10.9μmの珪藻土微粉末からなる濾層を形成した。
次いで、前記濁り液の残部(白色沈殿も含む)と濾層形成時に回収した濾液とを再度前記濾層上に注ぎ、濾過器に蓋をして上部より窒素圧0.05~0.1MPaをかけたところ、驚いたことに、得られた濾液は全量が微黄色ほぼ透明均一液体であり、その重量は248gであった。
次いで、前記実施例1と同様の手法でこの濾液からトルエンを留去することにより、平均組成式MD330DR*11 45DR*32 30DR*24 5M で表される液状の高純度多価アルコール誘導体変性シリコーンNo.6とカプリリルメチコンとからなる組成物を、白黄色半透明均一の非常に粘稠な液体として得た。(収量123g) 式中、R*11、R*32及びR*24は下記のとおりである。
R*11= -C16H33
R*32=-C2H4Si(OSiMe3)3
R*24=-C3H6O-(C3H6O2)n-H, n=4.0
<液状の高純度多価アルコール誘導体変性シリコーンNo.7を含む組成物の調製>
反応器に製造例7で得られた乳白色粘稠液体(多価アルコール誘導体変性シリコーンNo.7を主成分として含む組成物) 150g、トルエン 120g、ポリビニルアルコール(PVA:重合度1500、白色粉粒状)4.5gを仕込み、70-80℃に加温して40分間攪拌混合したのち室温まで放冷した。
前記実施例6の場合と同様に、加圧濾過器、目皿、濾紙、受け器をセットし、同様の手法により主として中間粒度10.9μmの珪藻土微粉末3gからなる濾層を形成、及び前記処理で得られた濁液状混合物をこの濾層に通すことにより、淡黄色半透明均一な濾液を得た。従って、このものは、平均組成式:MD45DR*31 1DR*24 1Mで表される液状の高純度多価アルコール誘導体変性シリコーンNo.7とトルエン(希釈剤)とからなる組成物と考えられ、上記変性シリコーンNo.7:希釈剤の重量(質量)比は5:4であり、前記式中、R*31及びR*24は下記のとおりである。
<液状の高純度多価アルコール誘導体変性シリコーンNo.8の調製>
反応器に製造例8で得られた土灰褐色の不透明粘性液体(多価アルコール誘導体変性シリコーンNo.8を主成分として含む組成物)を180g、カルボキシビニルポリマー(別名:カルボマー、白色微粉末)5.4gを仕込み、60-85℃に加温して1時間攪拌混合した。その後、攪拌下に35℃まで放冷し、乳濁粘性液状物を得た。
タンク付きステンレスホルダーADVANTEC KST-90に、直径90mmのガラス繊維濾紙GC-90(保留粒子径0.5μm)をセットし、漏れの起こらないようタンク部とベースプレート(O-リング、濾紙、サポートスクリーンを置く部分)とを専用のボルト、ワッシャー、ナットにより締め付けて固定した。これにより、濾紙の縁部全体が上下から締め付けられ、漏れを防ぐ構造となる。
タンク上部の開口部より、前述の処理で得られた濁り液を投入したのち、開口部をタンクキャップで閉じ、窒素圧0.4MPaをかけて濾過を行なった。比較例8-2のケースとは異なり褐色ほぼ透明な濾液が得られたが、およそ5g出たところで目詰まりが生じ、濾液の落下が止まっていた。この現象は、濁り成分である液状の親水性不純物が、本発明おける親水性不純物を捕捉可能な固体粒子(ここではカルボマー粉体)に取り込まれ固体化された結果、これらがフィルター上に密に堆積して目詰まりを起こしたと理解できる。そして、分離された主成分の液は、当初の濁りが大幅に低減されほぼ透明な外観であった。したがって、本発明の動作原理が証明されたと考えられる。これに対して比較例8-2は、本発明における親水性不純物を捕捉可能な固体粒子による処理を行っていない点を除き、実施例8と全く同じ条件で濾過を行なったものであるが、濾過の前後で濁りは全く低減できていなかった。このことは、濁り成分がフィルターの細孔(0.5μm未満)を全く目詰まり無く通過したことを意味し、組成物中の濁り成分が液として存在していることを示している。
<液状の高純度多価アルコール誘導体変性シリコーンNo.8の調製>
反応器に製造例8で得られた土灰褐色の不透明粘性液体(多価アルコール誘導体変性シリコーンNo.8を主成分として含む組成物)を180g、カルボキシビニルポリマー(別名:カルボマー、白色微粉末)5.4gを仕込み、60-85℃に加温して1時間攪拌混合した。その後、攪拌下に35℃まで放冷し、乳濁粘性液状物を得た。
前記実施例8の場合と同様に、タンク付きステンレスホルダーADVANTEC KST-90に、直径90mmのガラス繊維濾紙GC-90(保留粒子径0.5μm)をセットし、漏れの起こらないようタンク部とベースプレート(O-リング、濾紙、サポートスクリーンを置く部分)とを専用のボルト、ワッシャー、ナットにより締め付けて固定した。
前記処理で得られた乳濁粘性液状物に、濾過時の目詰まりを抑制する目的で中間粒度46.5μmの珪藻土粉末5gを加え、ヘラでよくかき混ぜてスラリー状とした。
タンク上部の開口部より前記スラリーを投入したのち、開口部をタンクキャップで閉じ、窒素圧0.4MPaをかけて濾過を行った。この結果、平均組成式:MD44.7DR*22 2Mで表される液状の高純度多価アルコール誘導体変性シリコーンNo.8を、濃褐色ほぼ透明均一粘性液体として得た。(収量149g ) ここで、前記式中、R*22は下記のとおりである。
R*22= -C3H6O-{CH2-CH(OH)-CH2O}2-H

前記実施例8と同様にして、タンク付きステンレスホルダーに直径90mmのガラス繊維濾紙GC-90(保留粒子径0.5μm)をセットし、タンク部とベースプレートとを締め付けて固定した。タンク上部の開口部より前記スラリーを投入したのち、開口部をタンクキャップで閉じ、窒素圧0.4MPaをかけて濾過を行った。この結果、濃褐色でやや半透明感ある粘性液体139g が得られた。
<液状の高純度多価アルコール誘導体変性シリコーンNo.9の調製>
反応器に製造例9で得られた微黄色液体(多価アルコール誘導体変性シリコーンNo.9を主成分として含む組成物)を180g、アルギン酸(白黄色微粉末)5.4g を仕込み、60-80℃に加温して50分間攪拌混合した。その後、50℃以下まで攪拌下に放冷し、停止して室温に戻したところ黄白色の沈殿物と白黄色ヘイズ上澄み液とに分離していた。濾過時の目詰まりを防止する目的で、これに中間粒度30.6μmの珪藻土粉末5gを加え、ヘラでよくかき混ぜてスラリー状とした。
前記実施例8と同様にして、タンク付きステンレスホルダーに直径90mmのガラス繊維濾紙GC-90(保留粒子径0.5μm)をセットし、タンク部とベースプレートとを締め付けて固定した。タンク上部の開口部より前記スラリーを投入したのち、開口部をタンクキャップで閉じ、窒素圧0.4MPaをかけて濾過を行った。この結果、平均組成式:R*25MD187MR*25で表される多価アルコール誘導体変性シリコーンNo.9を、無色透明均一液体として得た。(収量161g) ここで、R*25は下記のとおりである。
R*25=-C3H6O-CH2(OH)-CH2-N{CH2CH(CH3)OH}2
<液状の高純度多価アルコール誘導体変性シリコーンNo.9の調製>
反応器に製造例9で得られた微黄色液体(多価アルコール誘導体変性シリコーンNo.9を主成分として含む組成物)を180g、カテキン水和物(茶白色粉末状)1.1g を仕込み、70-80℃に加温して55分間攪拌混合した。その後、40℃以下まで攪拌下に放冷し内容物を確認したところ、透明と思われる液中に朱色の粉末が分散した状況であった。濾過時の目詰まりを防止する目的で、これに中間粒度10.9μmの珪藻土微粉末3gを加え、ヘラでよくかき混ぜてスラリー状とした。
前記実施例8と同様にして、タンク付きステンレスホルダーに直径90mmのガラス繊維濾紙GC-90(保留粒子径0.5μm)をセットし、タンク部とベースプレートとを締め付けて固定した。タンク上部の開口部より前記スラリーを投入したのち、開口部をタンクキャップで閉じ、窒素圧0.4MPaをかけて濾過を行った。この結果、平均組成式:R*25MD187MR*25で表される多価アルコール誘導体変性シリコーンNo.9を、微黄色透明均一液体として得た。(収量166g) ここで、R*25は下記のとおりである。

実施例4-3及び比較例4の試料、実施例8-2及び比較例8-2の試料、実施例9、実施例9-2及び比較例9の試料について、前処理により水酸基をトリメチルシリル化(TMS)封鎖したのち、トルエンを溶離液としてGPC測定を行なうことにより、主成分の多価アルコール誘導体変性シリコーンに由来するピークと残存親水性不純物に由来するピークとの面積比を求めた。
但し、実施例9、実施例9-2及び比較例9の試料については活性アミノ基(GPCカラムに吸着する)を含有する可能性があるため、前記水酸基のTMS封鎖の後、更にアミノ基のエトキシカルボニル化封鎖を行なってから、GPC測定に供した。
また、このとき親水性不純物に由来するピーク位置決定の参考とするため、原料である高純度鎖状ジグリセリンモノアリルエーテル(グリセリン単位の繰り返し数=2)についても同様に水酸基を封鎖して、同様にGPC測定を行なった。以下に前処理及びGPC測定の条件を示す。また、結果を表4に示す。
試料約0.5g(高純度鎖状ジグリセリンモノアリルエーテルは約0.1g)を試験管に精秤し、試薬特級グレードのトルエン1mLで希釈した。
試料中に含まれる水酸基のモル数の3倍モルに相当する、N,O-ビス(トリメチルシリル)アセトアミドを添加し、軽く振り混ぜ混合した。この段階では、混合液は白濁ないしは不均質であった。
試験管に冷却管を取り付けてトルエン還流下で1時間処理を行った。この反応液の外観を確認した所、ほとんど透明均一な液体に変化していた。
試験管内の反応液を適量バイアル瓶に精秤し、試薬特級グレードのトルエンを添加し希釈することによって、計算上の試料濃度1重量%であるGPC測定用サンプル溶液を得た。
実施例9、実施例9-2及び比較例9に対応する前記GPC測定用サンプル溶液に対しては、試料中に含まれるアミノ基のモル数の6倍モルに相当する、ジエチルピロカルボナートを添加し、振り混ぜ混合均一化したものをGPC測定用サンプル溶液とした。

本発明に係る高純度化処理前後の試料(未処理:比較例4、比較例8-2、比較例9、処理後:実施例4-3、実施例8-2、実施例9及び実施例9-2)を前述のとおりGPC測定に供し、得られた分子量分布曲線の解析により、主成分たる多価アルコール誘導体変性シリコーン由来のピーク面積に対する残存親水性不純物由来のピーク面積の比率を求め、下表4にまとめた。
200mLガラス瓶に入れた実施例1、実施例1-2、実施例2、実施例2-2、実施例3、実施例3-2、実施例3-3、実施例4、実施例4-2、実施例4-3、及び、比較例1~4の試料を、室温(夏場は30℃付近~冬場は15℃付近まで変化)で1年間静置した後、各試料の外観変化を観察した。結果を表5に示す。
より極端な温度変化に対する外観の安定性(透明性への影響)を確認するため、実施例3-3、実施例4、実施例2-2、実施例6、実施例8-2、実施例9、実施例9-2、比較例9の試料を50℃恒温槽中に入れて1晩静置した。一方、実施例2-2、実施例4-3、実施例6、実施例8-2、実施例9、実施例9-2、比較例9の試料は0℃冷蔵庫中に入れて1晩静置した。結果を表6に示す。
