In liquid-liquid extraction using wetted-wall columns, analysis is possible only by dimensionless groups (75) for the core fluid, flowing up inside the tube, k varies as approximately D and for the fluid falling down the inner walls, varies as Systems studied include phenol-kerosene-water, acetic acid-methylisobutylketone-water, and uranyl nitrate between water and organic solvents (7S, 80-82) interfacial resistances of the order 100 sec.cm." are observed in the last system. These resistances are interpreted as being caused by a rather slow third-order interfacial exchange of of solvent molecules (S) coordinated about each UOa" ion ... 

With the system n-butylamine-kerosene-water (a difficult system) in a 16-in.-diameter tower, 10-in. disk diameter, 4-in. compartment height, 12-in. baffle opening, total flow was 91.2 cu. ft./(hr.)(sq. ft.), and HETS was 2 ft., corresponding to a throughput/volume of a theoretical stage = 45.6 hr.-1. 

T = 7 . above which the liquid and gas phase are no longer distinguishable. Since the liquid can he continuously converted into Ihe gas phase without discontinuous change of properties by any path in the P — T diagram passing above the critical point, there is no definite boundary between liquid and gas. Two liquids ol similar molecules are usually. soluble in all proportions, but very low solubility is sufficiently common to permit the demonstration of as many as seven separate liquid phases in equilibrium at one temperature and pressure (mercury, gallium, phosphorus. perHuoro-kerosene, water, aniline, and heptane at 50 C. I atmosphere). 

It was not recommended to open the unexploded criminal bombs unless they were previously kept for a while in liquids, such as chloroform or kerosene. Water could not be used because some bombs contained metallic K or Na as primers. Contact with w caused these metals to inflame.(A brief description of criminal bombs will be given under Explosives and Weapons Used by Anarchists and Revolutionists)...

Relations between slip velocity, holdup, and drop diameter, from the data of Letan and Kehat (L5) for a 3-in. column (kerosene-water system), are illustrated in Fig. 13. The increase in drop diameter with increasing holdup and decreasing slip velocity has some effect on the transfer area per unit volume, which nevertheless increases with decreasing Volumetric transfer coefficients increase correspondingly. 

From die above it can be concluded that for exfraction widi SC CO2 or Kerosene, water is not a necessary atfribute. With SFE, however, an expected extraction as fest as for leaching at pH=3 was not observed. This might be explained either ly formation and/or precipitation of (bi-)carbonates or by decrease of humidity. In contrast with aqueous leaching of Pb at p, where unexpectedly the EE decreased with time, die extraction of Pb during the continuous SFE kept rising in time. With SE, the initial exfraction of Zn from dry...
