Abstract
A reaction analysis device specifies a reaction state of a reaction fluid flowing through a flow reactor. The reaction analysis device includes a processor configured to specify the reaction state of the reaction fluid based on a reaction parameter indicating the reaction state of the reaction fluid which is obtained from a temperature distribution of the reaction fluid immediately after a reaction starts in a flow direction of the reaction fluid.
