Interpretive Summary:

Technical Abstract: Studies of extraction and reactions of chemical compounds in sub- and supercritical water require fabrication of specialized equipment that are compatible with these experimental conditions. Such equipment has been constructed in our laboratory for conducting "green" chemistry using both CO2 and water as solvents. Included in this presentation are descriptions and utilization of a batch and dynamic flow system for studying the hydrolysis of vegetable oils at temperatures and pressures ranging from 250-375 deg C and 100-400 atm. In addition, modification of a commercial view cell to study the density and phase behavior of water/oil systems is described, along with reconfiguration of a commercially available SC-CO2 based extractor for operation under subcritical water conditions up to 300 deg C and 425 atm). Examples will be given of utilizing the above equipment in process development studies, reaction chemistry, and chemical analysis.
