With effect of solvent extraction separation for pharmaceutical intermediates
Pharmaceutical intermediates of extraction separation, mainly using the solvent extraction method for liquid -
Liquid mixing and separation process, the use of this kind of operation process is to put the required material transfer from one phase to another phase, so as to achieve extraction separation, purification, to impurities such as purpose.
in the pharmaceutical intermediates extraction process, the former mainly adopts extraction tower or reaction kettle is more, with the progress of technology, people more and more is also high to the requirement of equipment.
The extraction effect of traditional equipment has amounted to less than ideal, in order to better meet customer demand, zhengzhou days extracting developed a new type of equipment -
Centrifugal extraction machine.
centrifugal extraction machine for pharmaceutical intermediates extraction separation, relies mainly on the centrifugal force will be rapid mixing and two phase fluid separation, mixing and mass transfer speed, mixing effect is comprehensive, extraction separation with high efficiency, no entrainment phenomenon, a greater quantity at the same time, more energy efficient.
in fact, is not only the pharmaceutical intermediates, centrifugal extraction machine in the field of fine chemical industry the application is very extensive, such as: raw material, extraction solvent, catalyst recovery section;
Acid recovery (
For example: acetic acid, phosphoric acid, etc. )
In the production of organic synthesis pickling, alkaline cleaning, such as reaction liquid extraction section.
centrifugal extraction machine can application in the field of pharmaceutical intermediates and other chemical so widespread, mainly due to its advantages.
Compared with the traditional extraction equipment, tianyi new centrifugal extraction machine has the following advantages:
1, the equipment enclosure with steel lining fluoride materials, drum made of fluorine material resistant to strong acid corrosion;
2, device, cover an area of an area small, low power consumption, more capacity, effectively reduce the comprehensive cost;
3, at the bottom of the bearing and mechanical seal, no leakage risk, reduce the maintenance cost of equipment and labor intensity;
4, high degree of automation, good operating environment;
5, which can realize continuous operation and intermittent operation, high extraction efficiency.
