Abstract
Description
冷却管を備えた200mL4つ口フラスコにトルエン79.8g、2−メチルフラン16.5g及び4−ホルミルモルホリン24.5gを入れ、35℃で攪拌した。この中に、同温度を保ちながら、ホスゲン21.5gを4時間かけて供給した。供給終了後、35℃で1時間保持した。ここまでの操作で、固体の析出は見られなかった。
冷却管を備えた200mL4つ口フラスコにトルエン79.8g、2−メチルフラン16.5g及びN,N−ジメチルホルムアミド28.7gを入れ、35℃で攪拌した。この中に、同温度を保ちながら、ホスゲン21.5gを4時間かけて供給した。ホスゲンの供給を開始して30分で固体が析出し、撹拌ができなくなった。
