Ethyl acetate solvent extraction technological process to extract penicillin

by:Deyuan      2020-09-04
In chemical pharmaceutical industry, the production of penicillin is common unit operation, and in the process of extraction, the solvent extraction effect is remarkable. Solvent extraction is to choose a suitable extraction solvent for extraction and separation of penicillin material liquids, high extraction efficiency, large quantity.

in view of the penicillin extraction, extraction solvent ethyl acetate, technique selection solvent extraction, equipment selection of common centrifugal extraction machine, extraction, extraction tower, reaction kettle, etc. Different extraction equipment for penicillin extraction rate is not the same, the capacity is different also.

in the near future a customer consultation of penicillin extraction equipment, the company before extraction tower is adopted to penicillin extraction, appeared in the process of operating capacity is small, entrainment, the phenomenon such as flooding, according to this kind of phenomenon, customers want to replacement of the equipment. I hope the company to provide the corresponding equipment and technology.

according to customer's problem, my company for its chose centrifugal extraction machine equipment, the ethyl acetate extraction agent selection. Concrete process is: compared with the extracting agent according to certain material liquids through different inlet into the centrifugal extraction machine, centrifugal force with centrifugal extraction machine will material liquid and extraction agent for rapid mixing and mass transfer, and then through the centrifugal shear force will contain organic phase of extraction agent and the solid-liquid separation, and through different discharging mouth eduction body.



the working principle of centrifugal extraction machine has essential difference with other extraction equipment, the characteristics of the centrifugal extraction machine advantages as follows:

1, equipment simple structure, stable, structure of suspension single fulcrum, processing area at the bottom of the bearing and mechanical seal, no leakage risk, solved the centrifugal extraction machine failure frequently, the problem of short service life, save the costs for equipment maintenance.

2, equipment capacity bigger, more energy saving, Under the condition of same capacity, its power consumption is a traditional annular structure of centrifugal extraction machine 1/10 ~ 1/3) 。 Equipment is available in using perfluorinated polymer materials, resistant to strong acid, Hydrochloric acid and mixed acid, etc. ) The corrosion.

3, mixing, separation effect is good - — A variety of hybrid structure is optional, high separation efficiency, can be applied to easily emulsifying system.
