摘要

PPROBLEM TO BE SOLVED: To obtain a reaction rate constant that does not include the influence of the mass diffusion time by using a microchannel, even when the time-series data of the reaction cannot be obtained. PSOLUTION: Two kinds of raw materials are adjusted by the concentration adjusting devices 3A and 3B to a predetermined concentration, and sent to raw material storage containers 5A and 5B by pumps 4A and 4B, and then they are sent through liquid feed pumps 6A and 6B and switching valves 7A and 7B to a plurality of microreactors 1A, 1B, 1C and 1D, in sequence which are adjusted to a predetermined temperature in a thermostatic chamber 13 and have different diffusion lengths. Reactant liquids that have been reacted in the respective microreactors are sent to product storage containers 9A, 9B, 9C and 9D and then are sent sequentially to a concentration measuring instrument 12, through the switching valve 10 and the pump 11, wherein the concentrations of the respective products are measured. The concentration data of the products is sent to an analysis device 14 and is compared with flow reaction analysis results for analyzing the reaction in the microreactors, and reaction rate constant is obtained.

要解决的问题：即使不能获得反应的时间序列数据，通过使用微通道来获得不包括质量扩散时间影响的反应速率常数。

解决方案：两种原料通过浓度调节装置3A和3B调节到预定浓度，然后通过泵4A和4B输送到原料存储容器5A和5B，然后通过送液泵输送图6A和6B中所示的阀和依次切换到多个微反应器1A，1B，1C和1D的切换阀7A和7B在恒温室13中被调节到预定温度并且具有不同的扩散长度。在各个微反应器中反应的反应液被送至产品存储容器9A，9B，9C和9D，然后通过切换阀10和泵11顺序地送至浓度测量仪器12，其中测量各个产品。将产物的浓度数据发送至分析装置14，并将其与流动反应分析结果进行比较以分析微反应器中的反应，并且获得反应速率常数。
