Abstract
Description
前記溶媒は、炭素数1〜5のアルキレンの1つ以上の水素がクロリンで置換された溶媒を使用する、ポリアルキレンカーボネートの製造方法が提供される。
溶液重合による溶媒確認実験1
スケールアップ(Scale up)時、工程の安定性のために、バルク重合から溶液重合に転換が行われるようにし、ZnGA−AA触媒を用いたPEC重合に適した溶媒をスクリーニングした(実験例1a〜1fと称する)。この時、酢酸はZnGA100重量部あたり1重量部で混合して、ZnGA−AA触媒を製造した。
溶液重合による溶媒確認実験2
溶媒としてメチレンクロライド(以下、MC)を使用したことを除いては、実施例1と同様の手順に従って、表2の条件でエチレンオキシドと二酸化炭素との共重合体を製造した。ZnGA−AA触媒とMCを用いた溶液重合による結果は表2および表3に示した。この時、反応器に投入される二酸化炭素は連続的に供給されるようにした。
実験例2の手順と同様に、2Lの高圧反応器で機械的アジテータを用いて撹拌し、下記表4の組成で溶液重合を実施した。エチレンオキシドと二酸化炭素との二元共重合体であるポリエチレンカーボネートを製造し、この時、二酸化炭素は連続的に供給された。
前記実験例1〜3の結果から、高温で長時間重合を進行させる時、最終生成物の組成において副産物のポリエチレングリコールの量が増加する傾向があることを確認することができた。したがって、これを改善すべく、表6のように、触媒のエチレンオキシドに対する比率を1:224で使用して、6時間の反応時間の間に溶液重合を進行させた。また、反応器は、CO2が連続的に投入可能なセミバッチ型(semi−batch type)反応器を用いた。さらに、触媒は、実験例1で使用されたのと同一のZnGA−AA触媒を使用した。
下記表7の組成でエチレンオキシドの重量対比の触媒当量と二酸化炭素の投入量を増加させて、ポリエチレンカーボネートを製造した。この時、反応器は、二酸化炭素が連続的に投入可能なセミバッチ型(semi−batch type)反応器を用いた。
ZnGA−AA触媒を用いたポリエチレンカーボネート溶媒重合時、反応時間の変化による重合結果を比較した。また、反応器は、二酸化炭素が連続的に投入可能なセミバッチ型(semi−batch type)反応器を用いた。
ZnGA−AA触媒を用いたポリエチレンカーボネート溶媒重合時、表9のように、溶媒量を変化させながらポリエチレンカーボネートを製造した。また、反応器は、二酸化炭素が連続的に投入可能なセミバッチ型(semi−batch type)反応器を用いた。
溶媒としてヘキサンを用いたことを除いては、実施例6および7と同様に共重合体を製造した。また、反応器は、CO2が連続的に投入可能なセミバッチ型(semi−batch type)反応器を用いた。
溶媒としてキシレンを用いたことを除いては、実施例6および7と同様に共重合体を製造した。また、反応器は、CO2が連続的に投入可能なセミバッチ型(semi−batch type)反応器を用いた。
溶媒としてアセトニトリルを用いて、実施例1と同様の方法でポリエチレンカーボネート(PEC)を製造しようとした。しかし、アセトニトリル下では反応が進行せず、ポリエチレンカーボネートを製造することができなかった。このような結果から、前記溶媒は溶液重合に適しないことを確認することができた。
下記表12の条件に従って、通常の方法でバルク重合を進行させて、PECを製造した。
