  • Accelerating rate calorimeter and method of operation
    Patent number: 4439048
    Abstract: The accelerating rate calorimeter disclosed herein is an instrument designed for accurately determining the adiabatic thermal runaway characteristics of reactive chemicals. The mode of operation involves measuring the adiabatic self-heat rate of exothermic chemical reactions to determine the acceleration of the reaction rate as a function of temperature. The basic instrument includes a sample vessel which is positioned inside a reaction chamber. The environment surrounding the sample vessel is a gas, such as air, or an inert gas, or it can be a vacuum environment. Separate heater means are provided for heating the reaction chamber and the sample vessel.During the exothermic reaction of the chemical in the sample vessel, the temperature of the reaction chamber and the sample vessel are continuously monitored by separate temperature sensing means.
    Type: Grant
    Filed: December 10, 1979
    Date of Patent: March 27, 1984
    Assignee: The Dow Chemical Company
    Inventors: Donald I. Townsend, Richard H. Solem, Edward E. Timm, Victor J. Caldecourt
