が起こりにくくなり、100゜Cを越えると、副反応が起こりやすくなる。
モノテルペン誘導体のチオシアン酸エステルの異性化は、反応溶媒を使用することにより行うことができる。反応溶媒としては、N,N−ジメチルホルムアミドなどのアミド類を用いることができる。反応温度は、通常好ましくは30〜80゜C、より好ましくは50〜120゜Cである。30゜C未満では、異性化が起こりにくくなり、180゜Cを超えると、副反応が起こりやすくなる。
<モノテルペン誘導体のイソチオシアン酸エステルの製造>
冷却管、温度計および攪拌機を設置した三口フラスコにゲラニオール88mlおよびジエチルエーテル50mlを仕込み、そこに細かく切断したナトリウム10gを加えた。そこに、ヨウ化カリウム2gを添加した後、1,10−ジブロモデカン100mlを約1時間かけて滴下し、さらに、エタノール300mlを約3時間かけて滴下し、還流条件下にて10時間反応させた。反応物を、エーテル抽出した後、カラムクロマトグラフィーによって精製し、中間体(モノテルペン誘導体)(1)を60g得た。
同様の装置にモノテルペン誘導体のチオシアン酸エステル(1)を39gおよびN,N−ジメチルホルムアミド200mlを仕込み、100゜Cにて25時間反応させた。反応生成物をエーテル抽出した後、カラムクロマトグラフィーによって精製し、モノテルペン誘導体のイソチオシアン酸エステル(1)を26g得た。
イソチオシアン酸エステル(1)を用いて、表2に示す配合割合により本発明の水中生物付着防止塗料を調製した。
前記水中生物付着防止塗料をFRP(ガラス繊維強化ポリエステル)板(150x300mm)の両面に、乾燥膜厚が70μmになるように刷毛塗りして試験板を作製した。この試験板を、兵庫県赤穂市坂越沖に設置したテスト用の筏から深度1.0mの海中に浸漬し、試験板表面の生物の付着状況を定期的に調査した。4ヶ月後および6ヶ月後の調査結果を表3に示す。コントロールとして、水中生物付着防止塗料を使用しなかった場合の結果を示す。
実施例1と同様の装置に、表1に示す所定量の各モノテルペン(A)およびジエチルエーテル50mlを仕込み、そこに細かく切断したナトリウム10gを加えた。そこに、ヨウ化カリウム2gを添加した後、表1に示す所定量の各ジブロモアルカン(B)を約1時間かけて滴下し、さらに、エタノール300mlを約3時間かけて滴下し、還流条件下にて10時間反応させた。反応物を、エーテル抽出した後、カラムクロマトグラフィーによって精製し、中間体(モノテルペン誘導体)(2)〜(9)を得た。得られた各中間体の収量を表1に示す。
同様の装置にモノテルペン誘導体のチオシアン酸エステル(2)〜(9)の表1に示す収量分およびN,N−ジメチルホルムアミド200mlを仕込み、100゜Cにて25時間反応させた。反応生成物をエーテル抽出した後、カラムクロマトグラフィーによって精製し、モノテルペン誘導体のイソチオシアン酸エステル(2)〜(9)を得た。得られたモノテルペン誘導体のイソチオシアン酸エステル(2)〜(9)の収量を表1に示す。
実施例1におけるイソチオシアン酸エステルに代えて亜酸化銅を用いて、表2に示す配合割合にて塗料を調製し、実施例1と同様にして水中生物付着防災性能の評価を行った。
結果を表3に示す。
市販の水中生物付着防止剤(ピリジントリフェニルボラン)を用いて表2に示す配合割合にて塗料を調製し、実施例1と同様にして水中生物付着防止性能の評価を行った。
結果を表3に示す。
実施例1と同様の装置に、ゲラニオール88mlおよびジエチルエーテル50mlを仕込み、そこに細かく切断したナトリウム10gを加えた。そこに、ヨウ化カリウム2gを添加した後、1,2−ジブロモエタン50mlを約1時間かけて滴下し、さらに、エタノール300mlを約3時間かけて滴下し、還流条件下にて10時間反応させた。反応物を、エーテル抽出した後、カラムクロマトグラフィーによって精製し、中間体(モノテルペン誘導体)(10)を53g得た。
同様の装置にモノテルペン誘導体のチオシアン酸エステル(10)を41gおよびN,N−ジメチルホルムアミド200mlを仕込み、100゜Cにて25時間反応させた。反応生成物をエーテル抽出した後、カラムクロマトグラフィーによって精製し、モノテルペン誘導体のイソチオシアン酸エステル(10)を20g得た。
