Development of a Microrectification Apparatus for Analytical and Preparative Applications

Abstract The realization of efficient microrectification equipment that can be operated intermittently or continuously is reported. The equipment can be used for both analytical and preparative separations of mixtures of liquid substances. Different binary systems were separated. A theoretical separation stage number of 12 was obtained, together with a height equivalent to one theoretical plate of 1.08 cm. Compared to the state of microtechnology, this can be regarded as excellent progress.
