Abstract: Finely-divided masses consisting mainly of calcium silicate or a mixture of calcium silicate and silicic acid are obtained by reacting a silicic acid sol or a suspension of a silicic acid hydrogel, having a maximum particle size of 0.3 m , with calcium hydroxide under atmospheric pressure, and then drying and grinding the product.  The reaction is preferably carried out at a temperature of 70-100 DEG  C. in a proportion of 1 mol. of calcium hydroxide to 2-4 mols. of silica.  The reaction product is in the form of lamell  about 5 m thick and with length and breadth between 50m  and 200m .  In an example a silicic acid sol is flowed into a suspension of calcium hydroxide with continuous stirring.  The pH falls from above 12 to between 9 and 10, and the product is recovered by centrifuging or filtration.  In another example a silicic acid hydrogel suspension is kneaded with calcium hydroxide, and the product dried and ground. Bulk densities down to 100 grams/litre are obtained.

Title: Improvements in and relating to the production of boron hydride compounds

IPC: C01B6/10
Filed: 1956-12-27
Abstract: Diborane is prepared by reacting calcium borohydride with a boron halide in the presence of an inert solvent for calcium borohydride. This reaction may be combined with the reaction of calcium hydride with B2H6 in two-step cyclic processes for the production of further quantities of B2H6 or Ca(BH4)2.  The boron halide may be boron trifluoride used as vapour, or in the solvent, and 0.5-1.5 mols. Ca(BH4)2 is dissolved in the solvent.  Solvents may be ethers of dipole moment, greater than 1.2, e.g. tetrahydrofuran or dimethyl ethers of glycols, and the reaction is preferably effected at above 40 DEG  C. with the solvent boiling under reflux. The product is distilled, and the distillate of B2H6 and solvent is condensed and fractionated.  An inert atmosphere of, say, nitrogen, should be used during the reaction.  To produce further quantities of B2H6 the reactions are: (1) 3B2H6+3CaH2=3Ca(BH4)2; (2) 3Ca(BH4)2+8BF3=3Ca(BF4)2 +4B2H6 and this cycle may be repeated, both steps being effected in the inert solvent.  Alternatively to produce further quantities of Ca(BH4)2, the distillate of B2H6 is contacted with a suspension of 0.8-2 mols. CaH2 in the solvent at above 40 DEG C. with the solvent boiling under reflux, the product is filtered, or centrifuged, and the solvent distilled off to leave a residue of Ca(BH4)2.2C4H8O in the case of tetrahydrofuran.
