Description
ヘキサン50.0kgに相当する容積容量を有する反応器において、常温で脱ゲル化を行った。反応器内でニッケル触媒を用いてポリブタジエンを合成した後に容積の確認を行うと、ヘキサン48.2kgの自由容積及びヘキサン約1.8kgの溶剤膨潤したゲル体積を示した。乾燥へキサンを用いてほぼ収容能力いっぱいまで反応器を満たした。窒素でパージした乾燥シクロヘキサン200mLに溶解した二塩化ビス(トリシクロヘキシルホスフィン)ベンジリデンルテニウム(IV)0.5gの懸濁液を調製した。この溶剤/脱ゲル化剤懸濁液を注入口から反応器に添加し、既に含まれている溶剤と混合した。混合物を攪拌機を用いて攪拌しながら16時間65℃に加熱した。この期間の後で、反応器の内容物を空にし、反応器の新たな容積の確認を行うと、ヘキサン50.0kgを示した。容積の確認の後に、反応器の内容物を空にして、反応器を使えるように戻した。その後、反応器内でネオジム触媒を用いてポリブタジエンを重合することに成功した。
ネオジム触媒を用いたポリブタジエン合成反応を行った後で、重合反応器に通じる管が部分的に塞がれたことを確認した。その結果、物質を系に圧送するときの過剰な圧力に注目した。窒素でパージした乾燥シクロへキサンを用いて管路を満たした。窒素でパージした乾燥シクロヘキサン500mLに溶解した二塩化トリシクロヘキシルホスフィン[1,3-ビス(2,4,6-トリメチルフェニル)-4,5-ジヒドロイミダゾール-2-イリデン][ベンジリデン]ルテニウム(IV)2gの懸濁液を管供給路に添加した。この溶剤/脱ゲル化剤懸濁液を連続ループ系に常温で圧送した。三時間以内に、路圧は138kPaに下がり、溶剤ラインフィルタを重合体の残留物と重合触媒の粒子で満たした。該フィルタを洗浄し、再循環処理を続けた。90分以内に69kPaの圧力の降下が観察され、管の圧力を標準的な作業圧力にまで下げた。
ニッケル触媒を用いてポリブタジエンを合成した後、重合反応器の自由容積がヘキサン49.4kgから37.6kgに減少した。反応器をヘキサンで満たし、窒素でパージした乾燥トルエン400mLに溶解した二塩化トリシクロヘキシルホスフィン[1,3-ビス(2,4,6-トリメチルフェニル)-4,5-ジヒドロイミダゾール-2-イリデン][ベンジリデン]ルテニウム(IV)2gの溶液を注入口から添加した。反応器の内容物を57℃に加熱し、20時間攪拌した。脱ゲル化処理の間に、ヘキサンの固体含有率は0.5%から3.7%に上昇し、可溶化した残留重合体の存在を示した。反応器の内容物を排出した後、反応器を新しい純へキサンで満たした。新たな容積がヘキサン49.3kgであることを確認し、反応器を使えるように戻した。
容積がヘキサン16.4kgであると確認した重合反応器が、ネオジム触媒を用いたポリブタジエン合成処理の後でゲルを含んでいることを確認した。該反応器は、溶剤膨潤したゲルを17容積%含み、自由容積はヘキサン13.6kgに減少した。ヘキサンに溶解した懸濁液として二塩化ビス(トリシクロヘキシルホスフィン)ベンジリデンルテニウム(IV)1gを反応器に添加した。反応器の内容物を攪拌しながら18時間40℃に加熱した。この期間の後で反応器の内容物を排出し、新たな容積の確認を行うと、反応器が完全に脱ゲル化(ヘキサン16.4kg)したことを示した。その後、反応器を温かいヘキサンでフラッシュし、使えるように戻した。次にリチウム触媒を用いたスチレン−ブタジエンゴムを該容器中で合成することに成功した。
ネオジム触媒を用いてポリブタジエンを重合反応器6.5ガロン(ヘキサン16.4kg)内で合成した。処理を完了した後、容積確認(ヘキサン13.1kg)によって反応器が約20%の溶剤膨潤したゲルを含むことを測定した。ヘキサンに溶解した懸濁液として二塩化ビス(トリシクロヘキシルホスフィン)ベンジリデンルテニウム(IV)1gを反応器に添加した。反応器の内容物を攪拌しながら24時間40℃に加熱した。この期間の後で反応器の内容物を排出し、新たな容積の確認を行うと、反応器が完全に脱ゲル化(ヘキサン16.4kg)したことを示した。その後、反応器を温かいヘキサンでフラッシュし、使えるように戻した。次にネオジム触媒を用いてポリブタジエンを該容器中で合成することに成功した。
ヘキサン16.4kgに相当する内容積を持つ重合反応器を、リチウム触媒を用いたスチレン−ブタジエンゴムの調製に利用した。処理を完了した後、反応器の容積の確認を行った。自由容積がヘキサン12.3kgに相当し、残りの容積は溶媒膨潤したゲルによって占有されたことを確認した。ヘキサンに溶解した懸濁液として二塩化ビス(トリシクロヘキシルホスフィン)ベンジリデンルテニウム(IV)1gを反応器に添加した。反応器の内容物を攪拌しながら24時間45℃に加熱した。この期間の後で反応器の内容物を排出し、新たな容積の確認を行うと、反応器が完全に脱ゲル化(ヘキサン16.4kg)したことを示した。その後、反応器を温かいヘキサンでフラッシュし、使えるように戻した。次にリチウム触媒を用いてスチレン−ブタジエンゴムを該容器中で合成することに成功した。
ヘキサン49.0kgに相当する容積容量を有する反応器において、常温で脱ゲル化を行った。反応器内でニッケル触媒を用いてポリブタジエンを合成した後に容積の確認を行うと、ヘキサン40.8kgの自由容積とヘキサン約8.2kgの溶剤膨潤したゲル体積を示した。乾燥へキサンを用いてほぼ収容能力いっぱいまで反応器を満たした。窒素でパージした乾燥シクロヘキサン830mLに溶解した二塩化ビス(トリシクロヘキシルホスフィン)ベンジリデンルテニウム(IV)2gの懸濁液を調製した。この溶剤/脱ゲル化剤懸濁液を注入口を通して反応器に添加し、既に含まれている溶剤と混合した。混合物を攪拌機を用いて攪拌しながら約2時間31℃に加熱した。その後、反応器の温度を約2.5時間上昇させ、脱ゲル化剤を失活させた。この期間の後にトリイソブチルアルコール300mLを添加して、反応器の温度を下げた。反応器の内容物を空にし、反応器の新たな容積の確認を行うと、ヘキサン49.0kgを示した。
