Δ2-头孢呋辛酯性质、用途与生产工艺
δ2-头孢呋辛酯，即(6R，7R)-3-氨基甲酰氧基甲基-7-[(Z)-2-(呋喃-2-基)-2-甲氧基亚氨基乙酰氨基]-3-头孢烯-4-羧酸1-乙酰氧乙基酯是头孢呋辛的1-乙酰氧乙基酯。是第二代头孢菌素类广谱抗菌剂，对革兰氏阳性微生物和革兰氏阴性微生物均有良好的抗菌活性。
δ2-头孢呋辛酯乙酸乙酯溶液在真空-0.99MPa下浓缩到30％，得到δ2-头孢呋辛酯浓缩液。
在25ml异丙醚或者石油醚中，加入0.2gδ2-头孢呋辛酯晶种，快速搅拌，得到头孢呋辛酯异丙醚或者δ2-头孢呋辛酯石油醚混悬液。
在δ2-头孢呋辛酯异丙醚或者δ2-头孢呋辛酯石油醚混悬液中，用2.5h同时匀速加入上述δ2-头孢呋辛酯浓缩液和800ml异丙醚或者石油醚溶液，然后养晶1h后过滤。
将过滤得到的晶体，用40ml体积用量比为1：5的乙酸乙酯异丙醚或者乙酸乙酯石油醚溶液洗涤，再用40ml异丙醚或者石油醚洗涤，在40℃下真空干燥,得到白色产物。
将白色产物通过喷雾干燥制备成无定型δ2-头孢呋辛酯，进而可以制成胶囊、片剂、颗粒或者分散片等口服制剂。
