Claim 6:
7. A microreactor system comprising:
a microreactor in a first stage that has two inflow ports into which fluids are introduced and a flow path configured to merge the fluids, and that is configured to mix a first-stage first fluid introduced from one of the inflow ports and a first-stage second fluid introduced from another one of the inflow ports in the flow path;
a plurality of microreactors in a second and subsequent stages disposed in series downstream of the microreactor in a first stage, each of the microreactors having two inflow ports into which fluids are introduced and a flow path configured to merge the fluids, and being configured to mix, in the flow path, a mixed fluid produced in the microreactor in a first stage and introduced from one of the inflow ports and fluids to be mixed introduced from another one of the inflow ports, respectively;
a first-stage first fluid container in which the first-stage first fluid is prepared;
a first-stage second fluid container in which the first-stage second fluid is prepared;
a plurality of containers for the fluids to be mixed that are provided for each of the microreactors in a second and subsequent stages and in which the fluids to be mixed are prepared;
a first-stage first fluid pump configured to feed the first-stage first fluid toward one of the inflow ports of the microreactor in a first stage;
a first-stage second fluid pump configured to feed the first-stage second fluid toward the other of the inflow ports of the microreactor in a first stage;
a plurality of pumps for the fluids to be mixed that are provided for each of the microreactors in a second and subsequent stages, and that are configured to feed the fluids to be mixed toward the other of the inflow ports of the microreactors in a second and subsequent stages;
a measurement unit for the first-stage first fluid that is configured to measure an amount of the first-stage first fluid in a first-stage first fluid container;
a measurement unit for the first-stage second fluid that is configured to measure an amount of the first-stage second fluid in a first-stage second fluid container;
a plurality of measurement units for the fluids to be mixed that are provided for each of the microreactors in a second and subsequent stages and that are configured to measure amounts of the fluids to be mixed in the containers for the fluids to be mixed;
a switching unit for the first-stage first fluid that is configured to switch the first-stage first fluid to be fed to the microreactor in a first stage to a fluid different from the first-stage first fluid, the first-stage second fluid, and the fluids to be mixed;
a switching unit for the first-stage second fluid that is configured to switch the first-stage second fluid to be fed to the microreactor in a first stage to a fluid different from the first-stage first fluid, the first-stage second fluid, and the fluids to be mixed; and
a plurality of switching units for the fluids to be mixed that are provided for each of the microreactors in a second and subsequent stages and that are configured to switch the fluids to be mixed to be fed to the microreactors in a second and subsequent stages to fluids different from the first-stage first fluid, the first-stage second fluid, and the fluids to be mixed.
