APPLICATION OF A NEW-TYPE OF SAFETY CALORIMETER

Safety production in chemical plants is a high-priority task, especial ly as concerns reactions which can change mechanism suddenly under def ined conditions, e.g. from a simple well-defined to an undesired autoc atalytic reaction. An example of this kind, the reaction of chloronitr obenzene with alkaline alcohol, was investigated with the new adiabati c precision calorimeter ACTRON 5, designed with a safety concept. It i s shown that the reaction can be interrupted safely under predicted co nditions.
