Chromatographic and Related Reactors.
Abstract
Several variations of gas and liquid column Chromatographic reactors were investigated. In connection with this, new information on the kinetics and course fo the base catalyzed esterification reaction of tetrachloroterephthaloyl chloride and its derivatives was obtained with Carbon-13 Nuclear Magnetic Resonance. The operation and conversion in a reverse phase liquid chromatographic reactor could be analyzed on a quantitative basis when consideration was given to the associative interaction between the stationary phase and elements of the mobile phase. Furthermore, the composition and models for the stationary phase could be examined on the basis of the kinetics of reaction of the tetrachloroterephthaloyl derivatives. A related procedure for determining the phase ratio was developed. Mass transfer limitations for chromatographic reactions were also analyzed. Incorporation of a void column between two packed liquid chromatographic columns made it possible to decouple esterification rate constants for both the mobile and stationary phase. The stopped flow liquid chromatographic reactor was found to be viable for conversions and operation but not amenable to quantitive analysis because of ionic strength effects with our systems. Operation of a version of the stopped flow gas chromatographic reactor was successful and applications to studies of catalytic reactions were demonstrated. The rate of the CO methanation reaction even could be measured at room temperature on supported nickel, ruthenium and cobalt catalysts.
