應(yīng)用
4-羥基-6-甲基-2-吡喃酮可作為fenridazon-k等化學(xué)雜交劑的關(guān)鍵中間體,用于實(shí)驗(yàn)室研發(fā)過(guò)程和化工生產(chǎn)研發(fā)中。制備
將14.4g(0.1mol)丙二酸亞異丙基酯,35ml二氯甲烷和15ml氯苯置于反應(yīng)瓶中,在攪拌下冷卻至<5℃,依次滴加10.1g(0.1mol)三乙胺和10.1g(0.12mol)雙乙烯酮。加畢緩慢升溫至室溫,繼續(xù)攪拌2小時(shí)。用冷卻的稀鹽酸充分洗滌反應(yīng)物,經(jīng)干燥、過(guò)濾后,在旋轉(zhuǎn)蒸發(fā)器中脫去大部份二氯甲烷。將殘余地反應(yīng)物加熱、回流2小時(shí),即有黃色結(jié)晶析出。冷卻使結(jié)晶、抽濾并用少量乙醚洗滌結(jié)晶。晾干后得4-羥基-6-甲基-2-吡喃酮10.1g,收率82%,m.p.186~189℃(文獻(xiàn)值188-189℃)。4-羥基-6-甲基-2-吡喃酮價(jià)格(試劑級(jí))
