反応混合物に水を加えて均一にした後に、メタノールとアセトニトリルを減圧留去した。残った水層にクロロホルム(50g)を加えて分液した後に、水層にクロロホルム(50g)を加えて抽出を行った。得られた有機層を合わせて、2%チオ硫酸ナトリウム水溶液(50g)、1規定リン酸水溶液(50g)、イオン交換水(50g)2回、で洗浄を行った後、真空ポンプで減圧乾燥した。結果、1,3,5-トリス-(2,3-エポキシプロピル)-イソシアヌレートが収量0.8g、収率28%、GC面積百分率純度は90%で得られた。
1,3,5-トリス-(4-ペンテニル)-イソシアヌレート(10.0g、30.0mmol)、アセトニトリル(11g、270.0mmol)、メタノール(30g)を混合し、温度を25℃とした後に、35質量%過酸化水素水溶液(23.2ml、270.0mmol)を15時間かけて滴下した。35質量%過酸化水素水溶液の滴下開始と同時に、8質量%水酸化ナトリウム水溶液を、反応溶液がpH=10.0乃至10.5に維持するように滴下し始めた。反応溶液をGCで分析したところ、オレフィンの転化率は99%であった。
得られた溶液をHPLCで分析したところ、1,3,5-トリス-(4,5-エポキシペンチル)-イソシアヌレートの収率は71%であることが確認された。
1,3,5-トリス-(4-ペンテニル)-イソシアヌレート(10.0g、30.0mmol)、リン酸三ナトリウム・12水和物(23.9g、63.0mmol)、アセトニトリル(11g、270.0mmol)、メタノール(30g)を混合し、温度を20℃とした後に、35質量%過酸化水素水溶液(7.74ml、90mmol)を1時間かけて滴下した後に4時間反応させた。更に、35質量%過酸化水素水溶液(7.74ml、90mmol)を1時間かけて滴下した後に4時間反応させることを2回繰り返した後に、追加で4時間反応させた。反応溶液をGCで分析したところ、オレフィンの転化率は99%であった。
反応混合物から無機塩を取り除くためにろ過を行い、得られた溶液をHPLCで分析したところ、1,3,5-トリス-(4,5-エポキシペンチル)-イソシアヌレートの収率は75%であることが確認された。
1,3,5-トリス-(10-ウンデセニル)-イソシアヌレート(5.3g、9.0mmol)、リン酸三ナトリウム・12水和物(7.2g、18.9mmol)、アセトニトリル(10g、243.0mmol)、メタノール(6g)、炭酸ナトリウム-炭酸水素ナトリウム緩衝溶液(ph=10.6)(10g)を混合し、温度を20℃とした後に、35質量%過酸化水素水溶液(2.32ml、27mmol)を1時間かけて滴下した後に2時間反応させた。更に、35質量%過酸化水素水溶液(2.32ml、27mmol)を1時間かけて滴下した後に2時間反応させることを3回繰り返した後に、追加で4時間反応させた。反応溶液をGCで分析したところ、オレフィンの転化率は0%であった。
