Ein 'Reagenzglas' für Hochdruck-Reaktionen in Wasser kritischen Zustandes, Konstruktion und Eigenschaften

Abstract

The construction principles and the thermal behavior of a laboratory-scale tubular batch reactor is described which is used for quick screening tests of reactions in fluid water near its critical state. Due to the direct high current electric heating of the tube, the reactor has a very low thermal inertia. Furthermore, this heating mode allows a rapid and homogeneous temperature control. These features bring down the time per experiment to two hours or less. However, the simple discontinuous mode has important consequences on the physical state of the charge: the initial charging degree of the reactor is a state parameter of decisive importance.
