Material or material mixture's thermodynamic condition e.g. reaction enthalpy, determining method for use in chemical industry, involves determining energy balance and thermodynamic conditions from measured values and energy contributions

摘要

The method involves maintaining isothermal conditions in a reactor inner area (4) by reactor wall and cover thermostats (A, B). Temperatures in a reactor wall (8) and a reactor cover (9) are detected independent of each other by a wall sensor (6) and a cover sensor (7). The isothermal conditions and a required temperature in a reactor (2) are produced and maintained by a control and evaluation device (10). Energy balance and thermodynamic conditions of a material or a material mixture are determined in a temporal process from measured values and energy contributions. Independent claims are also included for the following: (1) a calorimeter for determining thermodynamic conditions of a material or a material mixture (2) a device for retrofitting a calorimeter.
