The structure and torsional properties of oxalyl chloride fluoride in the gas phase have been measured by electron diffraction at temperatures of 22, 81, 158, and 310 °C. The molecule may be regarded as a hybrid of oxalyl chloride and oxalyl fluorid

The molecular structure and composition of gaseous oxalyl fluoride (OXF) has been investigated by electron diffraction (GED) at nozzle-tip temperatures of −10, 149, and 219 °C. The GED data were augmented by molecular orbital calculations, and the

A membrane-based extraction process is described for the fractionation of citrus oils to produce an oil stream enriched in oxygenated components. The process relies on the high selectivity of cyclodextrins (CDs) to preferentially bind the desirable o

A design concept is described for a synergistic hybrid process for separating process streams into two component streams: a solute-rich stream and a solvent-rich stream. This hybrid design concept, which is particularly well-suited for membrane-based

The use of a supported-liquid membrane to separate citric acid from the beer produced by fermentation was studied. The liquid membrane consisted of an organic solution composed of trilaurylamine and a long-chain alcohol dissolved in an inert hydrocar

One of the key challenges facing NASA engineers is the development of systems for separating liquids and gases in microgravity environments. In this paper, a novel membrane-based phase separator is described. This device, known as a water recovery he
