Description
2lのジャーファーメンターに、p−プロピルフェノール100gおよびラッカーゼ(ダイワ化成社製)5gをリン酸緩衝液(pH=4.5)750mlおよびアセトン250mlに添加し、50℃で3時間通気攪拌を行った。反応終了後、分液により有機層を分離後、減圧蒸留して残存するp−プロピルフェノールを留去した。残渣をヘプタン、トルエンで再結晶を繰り返し、2,2’−ジヒドロキシ−5,5’−ジプロピルビフェニルを20g得た。(収率:20%)
反応終了後および再結晶後のサンプルについて下記の条件にてHPLC分析を行い精製後の2,2’−ジヒドロキシ−5,5’−ジプロピルビフェニルの純度が95%であることを確認した。反応終了後の反応物および精製後の2,2’−ジヒドロキシ−5,5’−ジプロピルビフェニルのHPLCチャートを図1および図2に示す。
