and doughnuts. A steady-state concentration profile measurement was used to evaluate the mass transfer and axial mixing coefficients for the nitric acid/water/30%TRPO (in kerosene) system in the pulsed extraction column with the diameter of 38 mm on the condition of the TRPO-kerosene solution as the continuous phase and the flow ratio of 1∶1. Experimental results indicate that Ey evaluated......
: Extraction of V(V) and Cr(III) from acidic sulfate leach liquors of ilmenite using 0.4 mol/L Aliquat 336 chloride in kerosene was carried out. Different parameters affecting the extraction process... of V(V) and Cr(III) from ilmenite leach sulfate solutions by 0.4 mol/L Aliquat 336 in kerosene was studied as a function of equilibrium time, sulfate concentration, Aliquat 336 concentration, equilibrium......
experiment under the condition of the organic phase composition 20% N235+10% isooctanol+70% sulfonated kerosene (volume fraction), assisting extraction agent concentration 0.1 mol/L, sulfuric acid......
NH4+, the optimal solvent extraction condition of copper was obtained in one-stage solvent extraction at phase ratio of 5:4 with 40% HR in sulphonated kerosene for 5 min. The copper concentration... sodium sulfate, vacuum distillation (1.45 kPa) yielded the product in the heart cut (95% purity; 38% yield; bp: 210-228 °C). (1) The diluent for the extractant was a type of sulphonated kerosene......
separation of cobalt from nickel by extraction using 30% trialkyl amine+50% kerosene (volume fraction) and tri-n-butylphosphate (TBP) as a phase modifier with the O/A ratio of 2?1, and stripping of cobalt..., commercially as N235 in China). The chemical structure is shown as follows: In experiment, the TBP and low odour kerosene were used as phase modifier and diluent, respectively. 2.2 Procedure In each......
+ phosphor particles with a narrow size distribution(2~4 μm) was obtained by firing the Y-Gd-Eu-BO3 precursor prepared in a W/O style emulsion system. In the W/O emulsion system, kerosene, used as oil phase......
. Kerosene with silicone oil as a foaming agent was used to evaluate the impact of bubble diameter (test series I). Frother solutions (MIBC, Dowfroth 250, Hexanol and F-150) were used for the solid type......
investigated. The products were characterized by NMR and MS. By using DHPA, DTMPPA and DDPA (10% in kerosene) as extractants, the extraction of Co2+ and Ni2+ in sulphate medium at different equilibrium pH values... of the extractants (60% neutralised) were prepared by adding stoichiometric amount of concentrated NaOH solution to the extractants in kerosene and stirring the phases to form a single phase. These solutions......
