Description
Technical field
The invention belongs to extraction kinetics research equipment technical field, particularly to a kind of split type laminar flow constant interfacial area cell and
Extracting process.
Background technology
Constant interfacial area cell is one of equipment of research extraction chemistry kinetics.By to extraction chemistry kinetics
Research can be that the structure of extraction equipment, size are submitted necessary information.
Since Lewis proposes the method for constant interfacial area cell method research extraction chemistry kinetics, occur in that two classes are permanent
Pond, interface:
First kind constant interfacial area cell be with document (chemistry circular, the 2nd phase in 1988, P32, etc.) be representative.Same
Two-layer stirring paddle is installed at the position up and down of root shaft.This shaft is inserted and is loaded with the container that immiscible weight is biphase
In, the stirring paddle on upper strata is used for stirring light phase, and the stirring paddle of lower floor is used for stirring heavy phase.During stirring, macroscopic view between weight is biphase
Separating surface keep stable, biphase mix homogeneously, the extraction chemistry between weight is biphase as much as possible in respective phase of weight
Reacting and occur at two interphase interfaces, the concentration change over time of the body phase internal object solute measuring light phase or heavy phase is closed
System, can speculate extractive reaction speed and judge the rate-determining steps of extraction rate.The original intention of constant interfacial area cell design is to eliminate phase
The internal diffusion impact on interfacial chemical reaction, the biphase separating surface simultaneously keeping macroscopic view is stable.But, in actual operation,
In order to eliminate phase internal diffusion, the boundary between stirring can cause weight biphase is difficult to keep stable.
Equations of The Second Kind constant interfacial area cell is, with CN 2197119Y as representative, teeter chamber biphase for weight is separately positioned on Heng Jie
The two ends in pond, face, are respectively adopted light phase stirring paddle and light phase and heavy phase are stirred by heavy phase stirring paddle, it is to avoid coaxial agitation
The problem that the two-phase interface brought is unstable.This kind of constant interfacial area cell is referred to as laminar flow constant interfacial area cell.In laminar flow constant interfacial area cell, light phase
The stirring paddle of room and heavy phase indoor must simultaneously work as the effect of two aspects: mixes and drain.The effect of mixing is by a certain
Concentration of component in mutually stirs as far as possible, eliminates the impact of interfacial reaction generation phase internal diffusion, and the acting on of drain
In, in the contact area that weight is biphase, the light phase upper and lower surface sequentially passing through light phase deflector, heavy phase sequentially passes through to be led through heavy phase
The upper and lower surface of stream plate, biphase is in Laminar Flow state when being contacted by interface plate.The advantage of this kind of laminar flow constant interfacial area cell
It is that of avoiding the disturbance stirring contact interface biphase to weight of stirring paddle, it is possible to obtain repeatability well extraction kinetics number
According to.But, the most fairly obvious in the shortcoming of this kind of laminar-type constant interfacial area cell, because the type selecting of stirring paddle, physical dimension, installation position
Flow field and the swabbing action of stirring paddle affecting teeter chamber in laminar flow constant interfacial area cell such as put, and the impact of the position of deflector is light phase
Or the flow field structure that heavy phase is in laminar flow constant interfacial area cell.If stirring paddle design selection or installation site are improper, its mixing and
Drainage just can not realize.And the type selecting of stirring paddle and installation site need rely on substantial amounts of verification experimental verification or need a large amount of
Simulation calculate checking, the suitability for different extractive reaction systems is bad.Meanwhile, this kind of laminar-type constant interfacial area cell, due to
The existence of light phase deflector, it has to the mode using side to insert changes interface plate, causes weight biphase easy in constant interfacial area cell
Leakage is occurred to cause that mutually altering contacts brings error.
