600ml容量のParr反応器を準備して120で2時間の間真空を取った後、内部をアルゴンに置換して温度を60に下げた。それ以後、140gのメチルシクロヘキサン及びMMAO(8.6wt%、イソヘプタン溶液)1.6ml(Al/Cr=1200)を注入し、前記0.5mMの触媒溶液5ml(2.5umol)を反応器に注入した。60barに合わされたエチレンラインのバルブを開けて反応器内をエチレンで満たした後、500rpmで15分間撹拌した。
エチレンラインバルブを閉め、反応器をドライアイス/アセトンバスを用いて0に冷やした後、未反応エチレンを徐々にventし、ノナン(GC internal standard)を1ml入れた。それ以後、反応器の液体部分をサンプルとして少し取って水でquenchし、有機層をPTFEシリンジフィルタでフィルタしてGC分析を行った。
前記製造例のサンプルをアルゴンガスが満たされた反応器に入れ、撹拌及びベントを繰り返して残留エチレンを最大限除去した後、非活性化剤として、帯電防止剤(高分子添加剤)の1種であるビス(2-ヒドロキシエチル)ペンタデシルアミン(Atmer 163)を投与して10分間撹拌した。また、生成物分離工程(例.蒸留)環境を組成するため、3.5時間の間150℃で加熱して熱履歴を与えた後、温度を常温(約25℃)に下げてから、GC分析を行った。
非活性化剤としてAtmer 163の代わりに、デカノールとAtmer 163の混合溶液を投与したことを除いては、前記実施例1と同じ方法で熱履歴を与えた後、GC分析を行った。
非活性化剤としてAtmer 163の代わりに、トリイソプロパノールアミン(triisopropanolamine,TIPA)を投与したことを除いては、前記実施例1と同じ方法で熱履歴を与えた後、GC分析を行った。
非活性化剤としてAtmer 163の代わりに、クアドロール(N, N, N, N-テトラキス(2-ヒドロキシプロピル)-エチレンジアミン(quadrol(N, N, N, N-tetrakis(2-hydroxypropyl)-ethylenediamine)を投与したことを除いては、前記実施例1と同じ方法で熱履歴を与えた後、GC分析を行った。
非活性化剤を投与しないことを除いては、前記実施例1と同じ方法で熱履歴を与えた後、GC分析を行った。
