Description
有機ホスファイト及びポリ有機ホスファイトは、プラスチック材料用の保存剤(例えば、酸化防止剤)を含む様々な用途に、及び触媒用の配位子として使用されている。しかしながら、ホスファイト配位子の安定性の維持は、問題となる可能性がある。効果的となるには、配位子及び関連した触媒は、反応条件下で安定でなければならない。配位子の安定性は、不純物、特に保存中に配位子において蓄積するものによって悪影響を受ける可能性がある。
9000〜10,000ppmの亜リン酸を含有する固体配位子A(0.3g)を3つの20mLのガラスバイアルの各々に計量導入し、示されたように溶解させる。次いで各溶液を0.20ミクロンの多孔度のシリンジフィルターを通して濾過する。濾過液を水で抽出し、水層をICによって分析する。結果を表1に要約する。
2250ppmの亜リン酸を含有する固体配位子A(1.0g)を20mLのガラスバイアルに計量導入し、周囲温度で少量のピリジンを含有するトルエン(8.0g)に溶解させる。次いで溶液を0.45ミクロンの多孔度のシリンジフィルターを通して濾過し、濾過液を水で抽出し、水層をICによって分析する。各実験を二度実施し、それぞれの平均値を表2に要約する。
以下の手順を商業的規模で行う:2,2’−ビフェノール(250部)及びピリジン(3.75部)をトルエン(1730部)に溶解させ、0〜5℃に冷却する。三塩化リン(289部)を添加し、スラリーを34〜35℃までゆっくりと加温し、18時間撹拌する。蒸留(120℃、大気圧)によって過剰の三塩化リンを除去する。得られた溶液を0〜5℃に冷却し、ピリジン(314部)を添加する。トルエン(1550部)中の4,4,6,6−テトラ−tert−ブチル−2,2’−ビフェノール(274部)の溶液を、5℃未満の温度に維持しつつ、よく撹拌しながら第1の溶液にゆっくりと添加する。得られたスラリーを、反応が完了するまで、12時間〜18時間、35℃までゆっくりと加温する。次いで水(1370部)を添加して酸性塩を溶解させ、水層を排出する。得られたトルエン層を共沸的に乾燥させ、5ミクロンのフィルターを通して濾過し、真空下で濃縮して残渣とし、次いでこれを酢酸エチルまたはプロピルから再結晶させる。得られた固体をイソプロパノールで粉末化し、次いで真空下で乾燥させると、配位子Aが結晶性粉末として得られる。この手法で調製された3つの異なる商業ロットは、最終生成物中に平均で77ppmの亜リン酸を含有する。
1288ppmの亜リン酸を含有する固体配位子A(0.3g)を20mLのガラスバイアルに計量導入し、周囲温度及び70℃でトルエン(6.5g)に溶解させる。溶液を5.0μのシリンジフィルターを通して濾過する。濾過液を水で抽出し、水層をICによって分析する。結果を表3に要約する。
1289ppmの亜リン酸を含有する固体配位子A(0.3g)を20mLのガラスバイアルに計量導入し、周囲温度でトルエン(6.5g)に溶解させる。溶液を様々な多孔度のシリンジフィルターを通して濾過する。濾過液を水で抽出し、水層をICによって分析する。結果を表4に要約する。
濾過直前に溶液を70℃に加熱すること以外は実施例1〜3の手順を繰り返す。結果を表5に要約する。
8986ppmの亜リン酸を含有する固体配位子A(0.3g)を20mLのガラスバイアルに計量導入し、40℃で1:1のトルエン:ヘプタン(6.0g)に溶解させる。溶液を0.45μのシリンジフィルターを通して濾過する。濾過液を水で抽出し、水層をICによって分析する。濾過後の配位子Aの亜リン酸含有量は29.2ppmである。
594ppmの亜リン酸を含有する固体配位子A(0.2g)を20mLのガラスバイアルに計量導入し、周囲温度でベンゼンまたはp−キシレン(7.0g)に溶解させる。溶液を0.20μのシリンジフィルターを通して濾過する。濾過液を水で抽出し、水層をICによって分析する。結果を表6に要約する。
65.3ppmの亜リン酸を含有する固体配位子A(0.3g)を20mLのガラスバイアルに計量導入し、周囲温度でトルエン(6.5g)に溶解させる。セライト(0.5gのCelite545;酸洗浄していない)を示されたように添加し、得られたスラリーを約5分間撹拌した。次いでスラリーを示されているようにガラスウールプラグまたはフィルターが装着されたシリンジに入れる。濾過液を水で抽出し、水層をICによって分析する。結果を表7に要約する。
採用した配位子Aが8986ppmの亜リン酸を含有すること以外は実施例10〜13の手順を繰り返す。結果を表8に要約する。
6041ppmの亜リン酸を含有する固体配位子B(0.1g)を20mLのガラスバイアルに計量導入し、周囲温度でトルエン(8.8g)に溶解させる。セライト(1.0gのCelite Standard Super−Cel)を添加し、得られたスラリーを約5分間撹拌する。次いでスラリーを、0.2μフィルターが装着されたシリンジに入れる。濾過液を回収し、水で抽出し、水性層をICによって分析する。有機ホスファイトの酸含有量は3.4ppmであると決定される。
41.5ppmの亜リン酸を含有する酢酸エチルから再結晶化された固体配位子A(10.9g)を200mLの丸底フラスコに計量導入し、周囲温度でトルエン(34.4g)に溶解させる。得られた溶液を0.2ミクロンのシリンジフィルターを通して濾過し、次いで濾過液を9.0gの残留トルエンを含有するスラッシュが達成されるまでロータリーエバポレーターで濃縮する。イソプロパノール(100mL)をスラッシュに添加し、混合物を70℃で約1時間粉末化する。次いで固体を回収し、イソプロパノール(30mL)で洗浄し、真空中で乾燥させる。このようにして得られた配位子Aは、0.7ppmの亜リン酸を含有する(元の亜リン酸の98.3%の除去)。
実施例21で調製された低酸固体配位子A(6g)及び様々な量の亜リン酸を含有する固体配位子Aの2つの追加サンプルを小さなガラス瓶に入れ、キャップをせずに放置し、塩化ナトリウムで飽和した少量の水を含有するより大きなガラス瓶に入れた。次いで最も外側の瓶をキャップし、40℃のオーブンに入れる。瓶内の相対湿度は75%である(Journal of Research of the National Bureau of Standards−A.Physics and Chemistry Vol.81 A,No.1,January−February 1977)サンプルを定期的に取り出し、静かに混合し、IC分析のためにサンプリングする。結果を表9に要約する。
