Abstract

In order to measure UV/VIS spectra and run small scale reactions under supercritical conditions an autoclave was built using the technique of an immersion-cell UV/VIS spectrophotometer which allows the use of just one optical window and a reflection unit inside the pressure chamber. The discussed system is easily installed into any existing autoclave and offers maximum security due to complete separation of measuring and pressure unit. The system was constructed to observe solvatochromic dyes in the supercritical phase in dependence of pressure and temperature.
