High-Pressure, High-Temperature Spectrophotometer Cell for in Situ Catalyst Identification

Part of the Developments in Applied Spectroscopy book series (DAIS, volume 10)


A high-pressure, high-temperature spectrophotometer cell has been designed and constructed in order to examine reacting solutions at conditions which are above ambient temperature and pressure. Large windows, a variable-path length, and a relatively compact design provide considerable versatility and permit the use of the cell interchangeably among a variety of commercially available IR and UV-Visible spectrophotometers without the need for special instrument modification. The cell has been used to study solutions at a variety of reaction conditions up to 100 atmospheres of pressure at 200°C without any suggestion of window or cell failure. The design and fabrication of the cell are reported. In addition, specific applications of the cell to studies of the rhodium-catalyzed hydroformylation of olefins are described.

    Thermistor Temperature Controller, Model 7115, purchased from Yellow Spring Instrument Company, Inc., Yellow Spring, Ohio, and modified by installing a 100 0 resistor in parallel with the probe in order to expand the temperature-range. Four 50 watt heaters were sufficient to maintain 200°C.Google Scholar
