Over the past years, superheated, close‐to‐critical and supercritical water (hot compressed water) have met with an increasing interest as reaction medium. In this work, a method for determining the residence time distribution of reactors with hot compressed water has been developed. In experiments performed in a testing plant residence time distribution was measured directly downstream of the reactor at high pressure and high temperature and by using a view cell together with an UV‐active tracer substance.
