Definitions
- the invention relates to a device for mixing and reacting multiphase gaseous and liquid mixtures, homogeneous immiscible liquid homogeneous solutions with homogeneous solutions in which several solid or liquid substances or several gases are dissolved in intensive contact with one another, and the use thereof Device and diphenyl carbonate and polycarbonate made with the device.
- a disadvantage of using stirrers or other mechanical mixers is the introduction of shaft bearings into the stirred tank or reactor and the passage of shafts from the stirred tank or reactor, on the one hand with regard to the sealing and on the other hand with regard to the cleaning of the known mixers. Therefore, the design of the shaft bearing as a shaft bushing for large stirred tanks is very complex and associated with great expense.
- stirred kettles or mixers cannot be enlarged arbitrarily, since a chemical reaction often takes place during mixing, so that the mixing and / or reaction enthalpy is released or required during the mixing process in the reactor.
- additional heat exchangers are necessary to discharge the enthalpy to the outside or to feed it into the interior of the reactor, since the ratio of the heat exchange area to the reactor volume becomes smaller and smaller as the radius of the stirred tank increases.
- the stirring boiler volume can be reduced by expanding the number of stirred tanks or the heat transport can be intensified by installing additional heat exchangers in the bypass flow.
- the invention is therefore based on the object to improve the known and previously described device for mixing and reacting multi-phase gaseous and liquid mixtures so that a small mixer is provided with little design effort, which does not require shaft bearings and shaft bushings to the previously to avoid the disadvantages described. Furthermore, the quality of the mixture should be improved.
- a nozzle mixer as a reactor with a cylindrical space for the entry of the first solution, at least one cylindrical chamber tapered relative to the space, in which the mixing and reaction of at least two solutions takes place, a cylindrical space for the Inlet of the second solution and a space for the exit of the mixed and reacted solutions from the nozzle mixer.
- the outlet space is provided with a conically widening cross section in a further embodiment of the invention.
- the transition between the cylindrical space and the tapered cylindrical chamber has sharp edges.
- the first stream of liquid enters the nozzle mixer via the cylindrical chamber in the direction of the conical space, the second stream perpendicularly into the middle cylindrical chamber of the nozzle mixer.
- the vertical entry of the second solution into the nozzle mixer takes place via several openings which, according to a further teaching of the invention, are arranged in a line distributed uniformly over the circumference in the inner wall of the chamber.
- the openings preferably run perpendicularly or at any flat angle to the longitudinal axis of the chamber.
- Some of the homogeneous solutions from solid, liquid and / or gaseous substances can be produced in one or more jacket mixers attached in front of the nozzle mixer.
- Each jacket mixer has a cylindrical mixing chamber through which the homogeneous liquid is passed, and a plurality of inlet pipes arranged symmetrically around the mixing chamber are provided for introducing the second liquid or gas to be dissolved into the jacket mixer. Furthermore, means for pulse-like entry of the
- Liquid or gas can be provided in the jacket mixer to further improve the degree of mixing.
- the cylindrical mixing space has an outer annular space and that the inlet pipes are designed as bores in the reactor wall.
- the bores in the reactor wall preferably run at a flat angle to the flow direction of the reactor. An angle of 45 ° has proven to be particularly advantageous.
- a further embodiment of the invention provides that the bores in the mixer wall are arranged in a ring, the bores being expediently arranged uniformly distributed over the circumference of each ring.
- a particularly good mixing results when eight bores are arranged on each ring and the bores of adjacent rings are arranged offset from one another in the flow direction by an angle of 45 °.
- the device for mixing and reacting heat exchangers can be connected upstream and downstream in order to reliably ensure the necessary heat exchange with the mixing and reaction space in order to maintain the required mixing or reaction temperature during mixing processes and reactions with enthalpy changes.
- Another teaching of the invention is the use of the aforementioned device for mixing aqueous alkaline phenolate, bisphenolate solutions or other polyvalent phenolate solutions with solid, liquid and / or gaseous substances dissolved in the solvent.
- a further teaching of the invention also relates to diphenyl carbonate and polycarbonate, each produced by the interfacial process from a heterogeneous mixture produced by mixing in the device according to the invention from an aqueous alkaline phenolate or bisphenolate solution with gaseous or liquid phosgene dissolved in dichloromethane, the mixture being a very has small residual phenylpiperidyl urethane content of ⁇ 20 ppm.
- a cascade of four stirred tanks with a total volume of 23 m 3 is flowed through by an aqueous reaction mixture at 30 ° C with a throughput of 4,500 kg / h, phosgene and dichloromethane being fed continuously into the first reactor.
- the aqueous phenolate solution is also continuously produced in a mixing vessel connected upstream of the first stirred tank in the cascade.
- reaction mixture is after the fourth stirred tank in a cascade
- Separation vessel separated into two phases, the organic phase cleaned, then the solvent and finally the diphenyl carbonate distilled.
- reaction mixture has now been conveyed through the device according to the invention with the same throughput, the solution of phosgene in dichloromethane being produced continuously in the jacket mixer.
- the aqueous phenolate solution was continuously produced in a mixing tank.
- Phenylpiperidylurethane can be safely reduced to values below 20 ppm, whereby a better quality of the diphenyl carbonate could be achieved.
- FIG. 1 shows a nozzle mixer according to the invention, cut
- Fig. 2 shows a jacket mixer according to the invention, partially cut
- FIG 3 shows a preferred arrangement of the mixers from FIGS. 1 and 2 in a schematic illustration.
- nozzle mixer is shown, the cylindrical central space for
- the four-part nozzle mixer D preferred in the exemplary embodiment shown contains a cylindrical space 1 into which a first solution F enters.
- a second solution F 2 flows over the cylindrical space 2 into a central cylindrical one
- Chamber 3 A conical space 4 serves as an outlet.
- the middle chamber 3 has one smaller diameter than the cylindrical space 1 and the transition between space 1 and chamber 3 is provided with sharp edges. With the help of the conically widening space 4 of the nozzle mixer D, it is possible to keep the pressure loss in the system low.
- the liquid for example the solution of phosgene in dichloromethane F
- the second solution is introduced into the cylindrical chamber 3 via openings 5 and mixed with the solution flowing perpendicularly therefrom from the room 1 and subjected to the reaction.
- the openings 5 are in a line on the cylindrical casing of the central chamber.
- FIG. 2 shows a cylindrical jacket mixer M to be connected upstream of the nozzle mixer D and which has a cylindrical mixing chamber 6, the wall of which is provided with a large number of bores 7, of which only the annular bores 7 near the entry E are provided for a better overview. are provided with reference numerals.
- rows of bores, rings 7A, 7B and 7C which are uniformly distributed in a ring-like manner over the length of the jacket mixer M, are arranged, of which only the left three rings are again designated for the sake of clarity.
- Each ring 7A, 7B, 7C preferably has eight bores 7 and the openings of two adjacent rings 7A, 7B and 7B, 7C are each offset by 45 ° from one another. In this way, optimal mixing in the interior of the mixing space 6 of the jacket mixer M is achieved.
