The present invention relates to a parallel polymerization reactor for reaction screening according to various polymerization reactions.

By identifying and evaluating the reaction characteristics between various chemical substances (hereinafter, referred to as raw material sources), efforts have been made to achieve results such as development of new materials and improvement of processes through the reactions.

However, in order to achieve the above-mentioned results, a large number of trial and error experiments should be carried out under various reaction conditions. As described above, the above-described chemical experiment involves a lot of trial and error, so it takes a long time to set up the reaction apparatus for the reaction as well as the time required for the reaction, and it is very inefficient to perform various experiments with different reaction conditions in one reactor. There was a problem that required a long time.

Accordingly, a parallel reactor having a plurality of reactors installed in parallel has been proposed.

1 shows an example of a conventional parallel reaction apparatus.

As shown in the drawing, the conventional parallel reaction apparatus includes a plurality of source receiving tanks 11 in which a raw material source is accommodated, and a flow meter 15 connected to each of the source receiving tanks 11 through an outlet pipe 26. And a valve 17 connected in series with the flow meter 15. The valve 17 is installed in communication with the vertical common pipe 25 through the inclined pipe 23. The inclined tube 23 is a pipe inclined downward with respect to the horizontal plane so that the raw material source flows downward by gravity without remaining in the interior of the inclined tube.

An injection tube 27 is connected to the lower end of the common tube 25. The injection tube 27 is branched into a plurality and extended in the longitudinal direction and connected to each of the plurality of reaction vessels 13. The reaction vessel 13 is arranged in parallel with respect to the common pipe 25 and accepts the raw material source that has been moved from the source receiving tank 11 so that the reaction takes place therein.

An upper portion of the common pipe 25 is provided with an inert gas tank 19 and a steam generator 21. The inert gas tank 19 is for drying the residual raw material source in the pipe. In addition, the steam generator 21 serves to heat the inert gas passing through the heat exchanger (28).

However, the above conventional parallel reaction apparatus has a disadvantage in that it can hardly be used for the reaction of a raw material source having any viscosity. In the above-described conventional parallel reaction apparatus, the raw material source is characterized by flowing the inclined tube 23 inclined at a predetermined angle by gravity and passing the flow meter 15 during which the raw material source flows the inclined tube by gravity. Furthermore, there must be some fluidity to pass through the meter. This means that the conventional parallel reactor described above cannot be used for the reaction of high viscosity raw material sources (unless there is a separate pressurizing means for pushing the raw material source), and can be used only when a raw material source with a large capacity of 50 liters or more is used. it means.

The present invention has been made to solve the above problems, and provided with a pressurized flow means for pushing the raw material source to the reactor side, even if the raw material source has a high viscosity can induce a rapid polymerization reaction through the pressure control in the quantitative cylinder Since the flow rate of the raw material source can be measured and the diameter of the pipe through which the raw material source passes can be minimized, the amount of the raw material source can be reduced by reducing the capacity of the source tank or the reaction chamber, which is economical An object of the present invention is to provide a parallel polymerization apparatus having a low environmental load.

In order to achieve the above object, the present invention includes a plurality of source tanks for receiving a raw material source to be polymerized therein; One or more quantitative cylinders connected to the source tank through a source discharge pipe and provided with an amount of raw material source to react from the source tank and maintained at a predetermined pressure and measuring a flow rate of the raw material source supplied from the source tank; A plurality of reaction chambers connected to the quantitative cylinders through a quantitative source supply pipe and receiving at least two raw material sources passing through the quantitative cylinders and reacting therein; One or more solvent holding tanks installed separately from the source tank and accommodating a solvent to be supplied to the reaction product and connected to the reaction chamber through a solvent discharge pipe; A controller for controlling the flow of the raw material source and the solvent and adjusting the reaction rate inside the reaction chamber; It is characterized in that it comprises a pressurized flow means for applying pressure to the raw material source to move the raw material source from the source tank to the reaction chamber.

In addition, each of the reaction chamber is characterized in that the reaction product discharge means for discharging the reaction product to the outside of the reaction chamber.

In addition, the reaction chamber is characterized in that it is further provided with a heater for heating the reaction chamber if necessary.

In addition, between the solvent holding tank and the reaction chamber is characterized in that a quantitative cylinder for measuring the flow rate of the solvent to move from the solvent holding tank to the reaction chamber is further characterized.

In addition, the pressurized flow means, characterized in that it comprises a pressurized gas pipe to press the inert gas into each source tank to push the raw material source to the pressure of the gas through the source discharge pipe to the metering cylinder.

In addition, the pressurized flow means, characterized in that it further comprises a pressurized gas pipe to press the inert gas into the solvent tank to the solvent inside the solvent tank is pushed by the pressure of the gas to the quantitative cylinder through the solvent discharge pipe.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing the overall configuration of a parallel polymerization reactor according to an embodiment of the present invention. Basically, the parallel polymerization reactor according to the present embodiment is a system essential for the screening of reactions having a viscosity in the reaction product. However, it can be used even when the reaction product does not have a viscosity.

Referring to the drawings, a parallel polymerization reaction apparatus according to the present embodiment, a plurality of source tanks 41 are arranged in parallel and receives the raw material source from the outside through the source supply pipe 41a and the source tank 41 ) And a plurality of quantitative cylinders 47 connected to the source tank 41, and a plurality of quantitative cylinders 47 connected to the source tank 41, and a plurality of polymerization reactions are performed therein. The reaction chamber 61, the other quantitative cylinder 49 is connected to the solvent holding tank 43 and connected to the reaction chamber 61, and controls the polymerization reaction through the flow control of the solvent and the raw material source And a control unit 71 and pressurized flow means for promoting the flow of the raw material source and the solvent.

First, the pressurized flow means is, for example, a compressor 73 for compressing an inert gas such as nitrogen gas or argon gas to a predetermined pressure, and is connected to the compressor 73 and extends in the longitudinal direction, and is compressed by the compressor 73. It includes a main pressurized gas pipe 45 for moving the inert gas to the required place.

The source tank 41 is a tank sealed to the outside, the upper end is provided with a pressurized gas pipe 45a, a vent pipe 41c, and a source supply pipe 41a, and the lower end is connected to a source discharge pipe 41b. do.

The pressurized gas pipe 45a is a passage through which the inert gas (hereinafter, pressurized gas) flowing in the main pressurized gas pipe 45 into the source tank 41 is connected to the main pressurized gas pipe 45. . The pressurized gas increases the internal pressure of the source tank 41 and serves to push the raw material source (with viscosity) to be discharged more quickly into the source discharge pipe 41b.

The source supply pipe 41a is connected to an external source source supply source (not shown) to guide the source source to the source tank 41. In particular, the source supply pipe (41a) is provided with a solenoid valve can control the introduction amount of the raw material source through the control unit 71.

The vent pipe 41c is located at the side of the pressurized gas pipe 45a, and if necessary, vents the gas inside the source tank 41 to reduce the pressure. The vent pipe 41c is provided with a pressure gauge 41d for indicating the pressure inside the source tank 41.

The lower portion of each of the source tanks 41 is provided with a fixed amount cylinder 47. The metering cylinder 47 is connected to the source tank 41 through the source discharge pipe 41b and measures the amount of the raw material source discharged from the source tank. The metering cylinder 47 is made of a transparent or translucent container so that the raw material source can be seen from the outside. In addition, it is preferable to form a scale on the quantitative cylinder 47 as if it is a measuring cylinder so as to visually check the amount of the raw material source. In addition, the internal pressure of the metering cylinder 47 is maintained at atmospheric pressure.

In particular, in this embodiment, one metering cylinder is installed in one source tank in a one-to-one correspondence, but the number of source tanks may vary depending on the case. For example, only one metering cylinder can be installed so that one metering cylinder can cover multiple source tanks.

The upper portion of the metering cylinder 47 is provided with a vacuum pipe 53a and a metering source supply pipe 47a at the lower side. The vacuum pipe 53a extends in the longitudinal direction and is connected to the vacuum pump 51. The plurality of metering cylinders 47 with respect to the vacuum pump 51 has a parallel connection structure. The vacuum pump 51 serves to extract the pressurized gas introduced into the metering cylinder 47 to the outside of the metering cylinder 47. Even if the pressurized gas is inert, it may affect the chemical reaction of the raw material source. Thus, the pressurized gas is discharged by using the vacuum pump 51.

In order to precisely control the amount of the raw material source supplied from the source tank 41 to the metering cylinder 47, a solenoid valve is installed in the source discharge pipe 41b. The solenoid valve can also be controlled to open and close by the control unit 71 to send the required amount of raw material source to the metering cylinder 47. In particular, when the raw material source moves from the source tank 41 to the fixed-quantity cylinder 47, the pressure of the pressurized gas acts so that the raw material source can move quickly. At this time, the force that the pressurized gas pushes the raw material source, that is, the internal pressure of each source tank 41 depends on the viscosity of the raw material source to be used.

According to the basic theory of hydrodynamics, in order to flow a fluid of different viscosity inside a tube of a predetermined diameter at a constant speed, the fluid must be pushed at different pressures according to the viscosity of the fluid. For example, high viscosity fluids have to be pushed to higher pressures and relatively low viscosity fluids have to be pushed to lower pressures. Therefore, the pressure of the pressurized gas passing through each of the pressurized gas pipes 45a depends on the viscosity of the raw material source supplied to each of the source tanks 41. The pressure provided to the source tank 41 is adjusted through a valve provided in the pressurized gas pipe 45a.

A main pressurized gas pipe 45 is also connected to each of the source discharge pipes 41b. Therefore, the raw material source supplied to the metering cylinder 47 can also be press-fitted into the metering source supply pipe 47a by the action of pressurized gas and quickly move to the corresponding reaction chamber 61. Of course, when the pressure is applied to the metering cylinder 47, the valve of the source tank 41 should be shut off so that the pressure is not applied to the source tank 41.

A lower portion of each of the metering cylinders 47 is provided with a metering source supply pipe 47a. The quantitative source supply pipe 47a is a pipeline for sending the raw material source passed through each quantitative cylinder 47 to the desired reaction chamber 61. The quantitative source supply pipe 47a is once combined into one pipe and branched to each reaction chamber 61. In particular, a plurality of solenoid valves are properly installed in the fixed-quantity source supply pipe 47a to control the opening and closing of the solenoid valve so that the raw material source can be selectively supplied to the desired reaction chamber.

On the other hand, the solvent receiving tank 43 provided separately from the source tank 41 is a closed tank for receiving the solvent. The solvent serves to dilute the polymerization reaction product remaining in the reaction chamber 61 after the completion of the polymerization reaction when the solvent has a large viscosity. The type of solvent therefore depends on the nature of the reaction product.

The upper portion of the solvent holding tank 43 is provided with a pressurized gas pipe 45a, a solvent supply pipe 43a, and a vent pipe 43c connected to the main pressurized gas pipe 45. The pressurized gas pipe 45a is a supply pipe which induces pressurized gas for pushing the solvent to the outside by raising the internal pressure of the solvent holding tank. In addition, the solvent supply pipe 43a is a pipe for supplying the solvent to the solvent holding tank 43, and the vent pipe 43c is an exhaust pipe for lowering the internal pressure of the solvent holding tank if necessary. The vent pipe 43c is provided with a pressure gauge 43d. The pressure gauge 43d measures the pressure inside the solvent holding tank 43.

A metering cylinder 49 is provided below the solvent holding tank 43. The quantitative cylinder 49 and the solvent holding tank 43 are connected to the solvent discharge pipe 43b. The solvent discharge pipe 43b is a passage for moving the solvent in the solvent holding tank 43 to the quantitative cylinder 49, and includes a plurality of solenoid valves for controlling the flow of the solvent. Of course, the solenoid valve is also controlled by the control unit 71.

The metering cylinder 49 has the same configuration as the metering cylinder 47 connected to the source tank 41 and has a vacuum pipe 53a thereon. The vacuum pipe 53a is for discharging the pressurized gas inside the metering cylinder 49 and is connected to the vacuum pump 51.

In addition, the lower portion of the metering cylinder 49 is provided with a metering solvent supply pipe (49a). The quantitative solvent supply pipe 49a is branched and connected to each reaction chamber 61. In addition, the branched solvent supply pipe 49a is provided with a solenoid valve 49c. Accordingly, the solvent may be supplied to the desired reaction chamber by appropriately adjusting the opening and closing of the solenoid valve 49c.

The reaction chamber 61 is arranged in parallel with each other to provide a sealed space for receiving at least two or more raw material sources to chemically react the raw material sources therein. In addition, the inside of the reaction chamber 61 is provided with a stirring blade 65 for promoting the reaction, the upper portion is provided with a motor 63 to rotate the stirring blade (65).

In addition, as described above, the reaction chamber 61 is connected to the end portions of the quantitative source supply pipe 47a, the quantitative solvent supply pipe 49a, and the vacuum pipe 53b.

The quantitative source supply pipe 47a is a pipe for guiding the raw material source supplied from the source tank 41 to the reaction chamber 61 and has a plurality of solenoid valves 47c for determining the flow path of the raw material source. Therefore, by controlling the solenoid valve 47c through the control unit 71, the raw material source contained in the desired source tank can be supplied to the desired reaction chamber 61. In addition, as described above, the solvent stored in the solvent accommodating tank 43 may also be supplied to the desired reaction chamber 61.

In addition, the vacuum pipe 53b is connected to the vacuum pump 51 as a passage for lowering the pressure inside the reaction chamber 61 or discharging the gas generated during the reaction. In addition, the vent pipe 61a is provided at the side of the motor 63. The vent pipe 61a is a passage through which the gas inside the reaction chamber 61 is discharged.

In addition, a reactant discharge tube 69 is provided below the reaction chamber 61. The reactant discharge pipe 69 is a passage for discharging the reaction product from the reaction chamber 61 after the polymerization reaction is completed. By installing the reactant discharge pipe 69, there is no need to open the reaction chamber 61 after the completion of the reaction, which is convenient. The diameter of the reactant discharge pipe 69 may be small as long as the solvent of the solvent receiving tank 43 can dilute the reaction product thinly.

Reference numeral 67 is a heater. The heater 67 is installed to surround the reaction chamber 61 and operates when heat is required for the polymerization reaction to heat the reaction chamber 61. The heating method of the heater 67 may vary depending on the case.

As a result, by appropriately controlling the solenoid valve and the gas pressurization means by the control unit 71, the desired amount of the raw material source can be provided to the (selected or all) reaction chamber to cause the polymerization reaction. In particular, since the polymerization reactions performed in each reaction chamber 61 are performed independently of each other, various information related to the reaction such as the reactivity and the reaction rate of the polymerization reactions in each reaction chamber can be obtained almost simultaneously.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.

Parallel polymerization reaction apparatus of the present invention made as described above is provided with a pressurized flow means for pushing the raw material source to the reactor side, even if the raw material source has a high viscosity can induce rapid polymerization reaction and pressure control in the quantitative cylinder Through this, the flow rate of the raw material source can be measured, and the diameter of the pipe through which the raw material source passes can be minimized. Therefore, the amount of the raw material source can be reduced by reducing the capacity of the source tank or the reaction chamber. Low environmental load due to
