青霉素G间歇反萃取工艺的优越性

萃取与反萃取是青霉素G提纯的重要步骤，选择适合的反萃取工艺对提高收率、保证质量起着决定性作用。本文论证了青霉素G间歇反萃取工艺的优点，并与连续反萃取工艺进行了比较及反萃取液(RK)的质量对结晶阶段影响作了详细论述。结论间歇式反萃取工艺更适合现代的青霉素提炼生产。

The advantageof batch antiextraction of penicillin G

Extraction and antiextraction is a important step of the purification of penicillin G.It has critical effect on improving yield and insuring quality to select the right antiextraction technology with continuous antiextraction technology.This passage has also detailed demonstra- tion about the effect of the quality of antiextraction liquid(RK) on the stage of crystallization.So the author draw a conclusion that antiextraction is more suited to modern refine production of penicillin G.
