White Crystal Powder Cesium Chloride CAS 7647-17-8 On Sale

Cesium chloride is a potassium channel blocker. Cesium chloride prevents a reduction in sodium ion transport produced by alloxan. Cesium chloride has induced arrhythmias, including pointy torsion ventricular tachycardia in animal models.

1. Dissolve cesium carbonate in a small amount of water. Add hydrochloric acid with relative density of 1.18 slowly under constant stirring and heat reaction:

Cs2CO3+ 2 HCl → 2 CsCl + 2 H2O + CO2

When pH=3, add cesium hydroxide to the solution after a boil for half an hour to bring the pH to neutral. Filtrate shall be filtered, evaporated and concentrated to precipitation of a large amount of crystal , cooled to room temperature, mother liquor shall be separated, cleaned and dried at 100 C, and the product shall be finished.

2. Cesium chloride can be obtained by dissolving cesium carbonate in hydrochloric acid and then concentrating the solution. Cesium chloride with purity of 99.5% is usually obtained and can be used directly. Caesium chloride which is not pure enough may be refined by the following methods.

Dissolve 15g cesium chloride in 100mL water after heating. The 24.2g mercury chloride was stoichiometric dissolved in 25mL 4mol hydrochloric acid. Add the HgCl2/HCl solution to the above solution while it is hot, stir and mix it, and cool it to precipitate CsHgCl3 crystallization. After suction and filtration, collect crystallization, discard mother liquor. Dissolve the crystals in 120mL hot water and cool them out again. For this reason, the recrystallization is repeated for 2-3 times, and the alkali metal can be reduced to less than 0.01%. Finally, the crystallization is dissolved in hot water, and H2S gas is injected to saturate the solution. Then HgS precipitation occurs, HgS are filtered out, filtrate is collected, and the filtrate is evaporated to dry to obtain pure cesium chloride.
