New apparatus for liquid-liquid extraction, "emulsion flow" extractor.
A simple and low-cost apparatus for continuous and efficient liquid-liquid extraction, which does not need continual mechanical forces (stirring, shaking, etc.) other than solution sending, has newly been developed. This apparatus, named "emulsion flow" extractor, is composed of a column part where an emulsified state fluid flow (emulsion flow) is generated by spraying micrometer-sized droplets...
متن کاملCountercurrent chromatography: a worthy technique for the direct measurement of liquid-liquid partition coefficients
Countercurrent chromatography (CCC) is a liquid chromatography technique in which the stationary phase is also a liquid. The solute separation is based on partitioning between the two immiscible liquid phases: the mobile phase and the support-free liquid stationary phase. Octanol-water partition coefficients (Po/w) of 17 βblockers and 17 sulphonamides were determined by CCC. Some of the Po/w co...
متن کاملThe Liquid Density of Complex Liquid Mixtures
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...
متن کاملPurification of specific restriction fragments of human deoxyribonucleic acid by using liquid countercurrent chromatography [proceedings].
Recent developments in cloning fragments of the eukaryotic genome larger than complimentary DNA copies of mRNA have led to interest in fractionation methods for restriction-enzyme digests of genomic DNA. Electrophoretic methods using agarose gels (Tonegawa et al., 1977) and column chromatography using RPC-5 (Hardies & Wells, 1976) are well known. The procedure described here exploits the differ...
متن کاملSolid-liquid separation after liquid-liquid extraction.
A low-melting solid is used as organic solvent for liquid-liquid extraction at elevated temperatures followed by solidification and decantation of the aqueous phase.
