  • Patent number: 9869595
    Abstract: A device which can be used as a flow reactor for synthesis and for discerning the reaction kinetics as well as a flow calorimeter is a need in the art. To fulfill this need, the invention discloses a simple calorimeter that functions as a device to measure reaction kinetics, preferably heat of reaction in a continuous manner, in adiabatic as well as in isothermal conditions. The distinct advantages of the device include online determination of thermokinetic properties, continuous determination of thermokinetic properties and applicable for determination in adiabatic as well as isothermal modes. The device may function independently or may be used in combination with reactors, micro reactors or tubular reactors.
