7-苯乙酰胺基-3-脱乙酰氧基头孢烷酸裂解工艺的改进

The Improvement of Cracked Technology of 7-Phenylacetamido-3- Desacetoxy Cephalosporanic Acid

青霉素氧化物扩环后，扩环酸母液直接裂解合成７－氨基脱乙酰氧头孢烷酸（７－ＡＤＣＡ），收率提高４１％。

After the ring enlargment of penicillin S-oxides,the liquor of 7-phenylacetamido-3-desacetoxy cephalosporanic acid is directly cracked to 7-ADCA,the yield is improved by about 4.1%,the quality can reach the professional standard.
