NaCl-KCl

KCl —NaCl —MgS04) and in many brines. Separated by fractional crystallization, soluble water and lower alcohols. Used in fertilizer production and to produce other potassium salts. 

A series of samples consisting of any possible combination of KCl, NaCl, and NH4CI is to be analyzed by adding AgN03 to precipitate AgCl. What is the minimum volume of 5% w/v AgN03 necessary to completely precipitate the chloride in any 0.5-g sample ... 

When magnesium oxide is chlorinated in the presence of powdered coke or coal (qv), anhydrous magnesium chloride is formed. In the production of magnesium metal, briquettes containing CaCl2, KCl, NaCl, MgO, and carbon are chlorinated at a temperature such that the electrolyte or cell melt collects at the bottom of the chlorinator, enabling the Hquid to be transferred directly to the electrolytic cells. 

KCl—NaCl—H2O, within this range is presented in Table 10. 

Beryllium. Beryllium [7440-41-7], Be, metal is produced by electrolysis of KCl—NaCl—BeCl2 melts. Temperatures up to 900°C are required. CeU voltages are 6 to 9 V (115). Electrolysis of mixtures of beryUium oxide [1304-56-9], BeO, ia lithium fluoride [7789-24-4], LiF, and beryUium fluoride [7787-49-7], BeF2, has produced beryUium metal at about 700°C and 2.6 V (116). DetaUs of fused salt metal winning processes are given ia Table 7.

The feasibility of strategies B and C has been demonstrated particularly for the synthesis of the so-called pericyclinosilanes (previously also named cyclo-silethynes [20]) 70-72 (Fig. 3). Historically, an approach of type C was the first one ever, in that [4]pericyclinosilane 70 was prepared by simple pyrolysis of a mixture of calcium carbide and dichlorodimethylsilane in a molten salt mixture of KCl/NaCl at 400°C, albeit in low yield (actual yield not reported) [21]. A... 

Vakarelski et al. [88] also investigated the adhesive forces between a colloid particle and a flat surface in solution. In their case they investigated a sihca sphere and a mica surface in chloride solutions of monovalent cations CsCl, KCl, NaCl, and LiCl. The pH was kept at 5.6 for all the experiments. To obtain the adhesive force in the presence of an electrostatic interaction, they summed the repulsive force and the pull-off force (coined foe by the authors ) to obtain a value for the adhesive force that is independent of the electrostatic component.

The importance of the virial-coefficient equations is especially great for mixed electrolytes. Of the needed virial coefficients for a complex mixture such as sea water, most are determined by the pure electrolyte measurements and all the others of any significance are determined from data on simple mixtures such as NaCl-KCl, NaCl-MgC, NaCl-Na.SO, etc., which have been measured. The effect of the terms obtained from mixtures is very small in any case and these terms can be ignored for all but the most abundant species.

Water with dissolved salt was more likely to lead to explosions, and the water temperature was less significant. (Related tests with molten KCl-NaCl mixtures poured into water led to explosions even for deep water pools or when soluble oils were present.)... 

Moreover, the adhesion depends strongly on the nature of the salt [105]. A pronounced difference is noted in Fig. 2.37, where the energy of adhesion with KCl, NaCl and LiCl are compared [110]. The system is much more adhesive with KCl. This is the contrary with a carboxylate surfactant [106,110]. This behavior is important because it suggests that the adhesion is linked to the solubility of the...
