“…Accordingly, the void zones can be identified as a small peak in the chromatogram. The dissociation of endo-dicyclopentadiene can be used to determine heterogeneities in the column packing [121].…”

Chromatographic reactors integrate chemical reaction and chromatographic separation in one apparatus. This offers potential for process intensification, especially in the case of equilibrium reactions. Different types of discontinuous and continuous processes as well as modeling of chromatographic reactors are described. Synthesis and design of this processes is very much influenced and often restricted by the type of reaction and the operating window which is set by the individual operating conditions for chemical reaction, mass separation, and equipment design. Integrated chromatographic reactors should be considered if chromatography is the favored separation process for a conventional sequential process design. Preparative chromatographic reactors are known for liquid‐ and gas‐phase processes. Laboratory‐scale applications are described. Analytical chromatographic reactors are used to determine reaction rate constants and kinetics, and to screen chromatographic systems and operating conditions for preparative applications. 1.

“…The effect of other molecular species on the permeation of organic molecules through a dimethyl polysiloxane membrane is the subject of another interesting report (679). Sheehan and Langer (842) used a new reaction kinetics approach to the detection of void zones in column packings permitting the estimation of void zone volumes as small as 0.5 cc (736).…”

review surveys developments in the field of gas chromatography since publication of the last review in this series (496) and covers the years 1970-71. Gas chromatography continues to be one of the most active areas in analytical chemistry. A recent report by the American Chemical Society ( 791) is based on the employment specialty choices of 84,925 chemists and chemical engineers who reported to the 1970 National Register of Scientific and Technical Personnel, an activity of
