Description
本発明の高純度トリフルオロメチル基置換芳香族ケトンの製造方法は、下記一般式(1)で示されるハロゲン置換ベンゾトリフルオライド化合物を出発基質とする。
検出器 : FID
カラム :TC−17,0.32mmφ×60m,0.25μm(J&W社製)
カラム温度:50℃(3.0分保持)→(10℃/分)→250℃(3.0分保持)
注入口温度:250℃
検出器温度:250℃
全流量 :62.6mL/分 (He 141.9kPa)
スプリット比:1/20
サンプル注入量:1.0μL
2. サンプル
10mlメスフラスコにサンプル0.2gを、電子上皿天秤を使用し秤量する。これにアセトンを加え、メスアップした溶液をサンプル溶液とした。
テトラヒドロフラン75.0g(1.04mol;nacalai tesque社製)、マグネシウム粉末5.1g(0.208mol;中央工産社製)、LiCl 2.5g(0.08mol;nacalai tesque社製)を温度計付き四つ口フラスコ(容量200ml)に投入し、系内を窒素置換しながら、撹拌した。これに1mol/LエチルマグネシウムブロミドTHF溶液0.5g(東京化成社製)を添加し、系内の水分を除去した。続いて、臭化エチル 0.44g(0.004mol;和光純薬社製)を加えた。暫く撹拌し、発熱が起こることを確認した。次に反応液温度45〜50℃に保ちながら、o−クロロベンゾトリフルオライド36.1g(0.2mol;和光純薬社製)を徐々に滴下した。滴下終了後、45℃で5時間撹拌しながら、熟成した。熟成後、トルエン 10.8gを加えて、希釈し、グリニャール試薬溶液を得た。
実施例1において、無水酢酸19.8g(0.19mol)を無水プロピオン酸25.2g(0.19mol;和光純薬社製)に変更した以外は、実施例1と同様に反応を行った。塩基性条件下での加水分解処理を行った後、油相に含まれる不純物プロピオン酸クロロブチルエステルおよびプロピオン酸トリフルオロメチルフェニルエステルの含有量は、含まれる2’−トリフルオロメチルプロピオフェノンに対して、それぞれ0.2%、0.1%であった。
実施例1において、塩基性条件下での加水分解処理を行わず、油相を取得した。この油相に含まれる不純物 酢酸クロロブチルエステルおよび酢酸トリフルオロメチルフェニルエステルの含有量は、含まれる2’−トリフルオロメチルアセトフェノンに対して、それぞれ2.5%、1.2%であった。これを減圧蒸留(減圧度0.4〜1.3kPa、留出温度95〜100℃)した結果、トータル収率62.5%(原料o−クロロベンゾトリフルオライド基準)で、GC純度97.2%の2’-トリフルオロメチルアセトフェノンを得た。不純物として、酢酸クロロブチルエステル 1.2%および酢酸トリフルオロメチルフェニルエステルの含有量は、0.7%であった。
実施例2において、塩基性条件下での加水分解処理を行わず、油相を取得した。この油相に含まれる不純物 プロピオン酸クロロブチルエステルおよびプロピオン酸トリフルオロメチルフェニルエステルの含有量は、含まれる2’−トリフルオロメチルプロピオフェノンに対して、それぞれ3.1%、1.4%であった。これを減圧蒸留(減圧度0.4〜1.3kPa、留出温度105〜110℃)した結果、トータル収率68.2%(原料o−クロロベンゾトリフルオライド基準)で、GC純度96.8%の2’−トリフルオロメチルプロピオフェノンを得た。不純物として、プロピオン酸クロロブチルエステル 1.5%およびプロピオン酸トリフルオロメチルフェニルエステルの含有量は、0.9%であった。
実施例1において、テトラn−ブチルアンモニウムプロミドを入れずに加水分解処理を行った以外、実施例1と同様に反応を行った。油相に含まれる不純物 酢酸クロロブチルエステルおよび酢酸トリフルオロメチルフェニルエステルの含有量は、含まれる2’−トリフルオロメチルアセトフェノンに対して、それぞれ0.5%、0.3%であった。さらに加水分解処理時間を延長し、10時間行ったところ、それぞれ0.3%、0.2%となった。
実施例2において、テトラn−ブチルアンモニウムプロミドを入れずに加水分解処理を行った以外、実施例2と同様に反応を行った。油相に含まれる不純物 プロピオン酸クロロブチルエステルおよびプロピオン酸トリフルオロメチルフェニルエステルの含有量は、含まれる2’−トリフルオロメチルプロピオフェノンに対して、それぞれ0.4%、0.2%であった。さらに加水分解処理時間を延長し、10時間行ったところ、それぞれ0.3%、0.1%となった。
