Description
了まで進行しているのが非常に好ましい。
る。この反応は発熱を伴う。一般に、反応によって生成される熱の一部を除去するために反応混合物を冷却するのが好ましい。この反応は、ターフェニル形成ステップと同じ反応容器において行われてもよい。その場合、硫黄の添加に先立って反応混合物を約0から約5℃の範囲の温度に冷却するのが好ましい。硫黄は、すべて一度に添加されてもよく、または約1から約2時間の範囲の時間にわたってなど経時的に複数回で漸増的に添加されてもよい。一態様において、温度は、硫黄の添加の間、約0から約15℃の範囲内に維持される。別の態様において、温度は、硫黄の添加の間、約0から約15℃の範囲内に維持される。反応生成物は、硫黄添加中に勢いよく撹拌されるのが好ましい。
水(705ml)中の濃塩酸(145ml)を滴加した。
に移した。硫黄(16.4g、0.511モル)をそのフラスコに入れた。ショートパス蒸留ヘッドを取り付け、大気圧でジクロロメタンを蒸留除去した。3.5時間にわたって、その反応混合物を66℃から226℃に加熱した。変換に続いてGCを行って、4−フェニルジベンゾ[b,d]チオフェンへの約64%の変換が達成された。234℃で3時間さらに加熱した後、反応生成物は完全な変換に達した。
な変化、変換及び/または反応は本開示に従って必要とされる条件下において特定の構成成分を一緒にしたことの当然の結果であるからである。したがって、構成成分は、所望の操作を実施することに関連して、または所望の組成物を形成する際に一緒にされる成分と見なされる。また、添付の請求項が、現在時制(「comprises」、「is」など)で物質、構成成分及び/または成分を言及する場合もあるがそれでも、その物質、構成成分または成分が、本開示に従って1つ以上の他の物質、構成成分及び/または成分と最初に接触、ブレンドまたは混合された直前の時点で存在していたため、その言及はその物質、構成成分または成分に対するものである。物質、構成成分または成分が、本開示及び化学者の通常の技術により行われる場合、接触、ブレンドまたは混合操作の過程の間に化学反応または変換によりその元々の本質を失う場合もあるという事実は、したがって、実質的な問題ではない。
