Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ...+ 2NH4Br + 4Br if the salt has not been dried over P,05. When thus dried, 60% of it decomposes according to the equation 3(NH4)2PtBr, --3Pt + i6HBr + 2NH4Br + 2N2. E. S. Hall. Recent Advances in Our Knowledge of Silicon and of Its Relations to Organized Structures. J. E. Reynolds. Chem. News, 100, 245-8.--A discourse delivered before the Royal Institution. It contains no new matter. The author advances a speculative theory as to the probability of a "high temperature protoplasm," containing Si in place of C and P instead of N, and points out that Si found in certain animal and plant cells may actually be a constituent of the protoplasm of such cells. W. C. Moork. The Action of Some Oxidizing Agents on Silicochloroform. A. Besson And L. Fournier. Compt. rend., 148, 1192-4.---SiHCl3 saturated with pure, dry O at about--800 and exposed, in a sealed tube, to sun-light for several days, shows a marked disengagement of HC1 and disappearance of free O. The residue, on distilling off the excess of SiHCl, consists of oxychlorides of Si, of which Si, Cl,0 was isolated. The change is similar to that undergone under like circumstances by CHCI3. Action of ozone at low temps, also produces Si, ClsO and a viscous liquid containing higher oxychlorides. NO, acts with great violence. When modified by use of CC14 as solvent, nitrosyl chloride is evolved. In the cold, SOs acts mildly on SiHCl, . Distillation of the residual liquid yields disulphuryl chloride, S2OsCl2. On carrying the distillation farther, evidence is given of formation of the oxide S, Os. The action of CrO, on SiHCl, is moderate at ordinary temp. The residue from distillation of the product gave rise to a brown powder of comp. Cr, OCl, . This is unstable in the air and dissolves in water with...show more
