Abstract

適用なし。
ここで、R1及びR2は、C4〜C18アルキル、C5〜C12シクロアルキル、フェニル、及びC7〜C15フェニルアルキルから独立して選択され;好ましくは、R1及びR2は、tert―ブチル、tert―アミル、tert―オクチル、シクロへキシル、α―メチルベンジル、又はα,α―ジメチルベンジルであり;最も好ましくは、tert―ブチル、tert―アミル、又はtert―オクチルである。R3はHである。
〈2,6―ジ―tert―ブチル―4―(3―フェニルプロプ―2―イニリデン)シクロヘキサ―2,5―ジエノン(7―フェニルアセチレンキノンメチド(7―Phace―QM))の合成〉
(a)2,6―ジ―tert―ブチル―4―(ピペリジン―1―イルメチレン)シクロヘキサ―2,5―ジエノン
ディーン―スタークトラップ、コンデンサ、マグネティックスターラーバー、及びストッパーを備える500mLの3口丸底フラスコの中に、以下の試剤、すなわち24.3g(100mmol)の3,5―ジ―tert―ブチル―4―ヒドロキシベンズアルデヒド、及び150mLのn―ヘプタンを加えた。次いで、フラスコに、21.7mL(200mmol)のピペリジンを入れた滴下漏斗を装着した。
ナトリウムフェニルアセチリドを、以下のように調製した。すなわち、コンデンサ、ストッパー、及びマグネティックスターラーを備えた1Lの三口フラスコに、13.5mL(120mmol)のフェニルアセチレン、及び100mLのトルエンを入れた。新たに切断した金属ナトリウムチップをフラスコに加え、内容物を還流の下、140℃に加熱した。加熱ブロックを使用した。全てのナトリウムが消費されると、淡褐色のスラリーが形成された。代替の方法において、臭化エチルマグネシウム、グリニャール試薬を、金属ナトリウムの代わりに用いた。更に他の方法において、水素化ナトリウムを使用した。スラリーを25℃まで冷却した。
マンニッヒ塩基2,6―ジ―tert―ブチル―4―(3―フェニル―1―(ピペリジン―1―イル)プロプ―2―イニル)フェノールを含む有機層を、ストッパー、マグネティックスターラーバー、滴下漏斗、及びコンデンサを備える1Lの三口フラスコの中に移した。フラスコを加熱ブロック上に置いた。20.2g(107mmol)のp―トルエンスルホン酸水溶液を滴状添加しつつ、内容物を120℃で還流した。1時間後に、p―トルエンスルホン酸の添加を完了した。反応混合物を室温に冷却した。
ディーン―スタークトラップ、コンデンサ、マグネティックスターラーバー、及びストッパーを備える1Lの三口丸底フラスコに、24.3g(100mmol)の3,5―ジ―tert―ブチル―4―ヒドロキシベンズアルデヒド、及び150mLのn―ヘプタンを加えた。フラスコに、21.7mL(200mmol)のピペリジンを含む滴下漏斗を装着した。
ピペリジンの代わりに、ピロリジンを、3,5―ジ―tert―ブチル―4―ヒドロキシベンズアルデヒドと共に使用して、例1(d)の手順に従い、その後の7―ピロリジニルキノンメチド中間体を合成した。7―Phace―QMへのワンポット手順の残りは、例1(d)において詳述したものとする。
従来技術の遅延剤である7―フェニル―キノンメチドのサンプルと、本発明の遅延剤である7―フェニルアセチレンキノンメチドのサンプルとの間の性能の比較を行った。それぞれの遅延剤のサンプルを、モノマーの質量に対して100ppmの用量で加えた。停止の間に重合の汚れを受けやすい、蒸留塔のリボイラーを模した、連続的に撹拌したタンク反応器の中に、それぞれの遅延剤のサンプルを入れた。それぞれのサンプルを120℃まで加熱し、0.5時間滞留させた。従来技術のサンプルは、結果として6429ppmの望ましくないポリマーとなり、本発明の遅延剤は、4236ppmだけの望ましくないポリマーを有した。これは、本発明の遅延剤が、従来技術の遅延剤と比較して、優れた性能を有することを実証している。
