Barium hexafluorosilicate

Disodium and barium hexafluorosilicate can also be used as fluorinating agents. High purity disodium hexafluorosilicate can be obtained from high purity diammonium hexafluorosilicate and sodium chloride. Diammonium hexafluorosilicate for this process is purified by sublimation.14... [Pg.642]

Disodium hexafluorosilicate converts phthaloyl chloride into phthaloyl fluoride in 51.5 % yield.15 Disodium and barium hexafluorosilicate can be used for the preparation of chloro-fluoromethanes. Thus, heating carbon tetrachloride with disodium hexafluorosilicate or barium hexafluorosilicate in an autolave under high pressure gives a mixture where dichlorodi-... [Pg.642]

Preparation of Barium Hexafluorosilicate, BaSiF 6. Twenty-five grams of barium chloride 2-hydrate (0.10 mol) is dissolved in 70 ml. of water. Aqueous fluorosilicic acid (30%) is added until precipitation is complete this requires about 40 ml. of the solution. The freshly precipitated barium hexafluorosilicate is filtered and washed until free from chloride. The product is dried in an oven at 110 to 120° and then dried further in a desiccator over phosphorus ) oxide or porous barium oxide. The yield is nearly quantitative. [Pg.145]
