6- Chlor-2- - -iodid

Platinum Chlor iodide, PtCl2I2, is described 6 as yielding brick-red, deliquescent prisms when platinum is dissolved in aqua regia in the presence of iodine. 

Ramie fibers consist of a very high proportion of pure cellulose. Therefore, treatment with iodine and sulfuric acid turns the fiber pure blue, but treating it with aniline sulfate gives no color. Treatment with zinc chlor-iodide reagent gives the fiber a blue color, while the fiber color is rose red when treated with calcium chlor-iodide [108]. 

Sodium was made from amalgam ia Germany duriag World War II (68). The only other commercial appHcation appears to be the Tekkosha process (74—76). In this method, preheated amalgam from a chlor—alkali cell is suppHed as anode to a second cell operating at 220—240°C. This cell has an electrolyte of fused sodium hydroxide, sodium iodide, and sodium cyanide and an iron cathode. Operating conditions are given ia Table 6.

Tekkosha An electrolytic process for obtaining sodium from the sodium amalgam formed in the chlor-alkali process. The electrolyte is a fused mixture of sodium hydroxide, sodium iodide, and sodium cyanide. The sodium deposits at the iron cathode. Developed by Tekkosha Company, Japan, in the 1960s and commercialized in 1971. 

Combustion, Flames and Explosion in Gases , 2nd Editn, Academic Press, NY (1961), 322—23 (Dust quenching occurs at a critical value of the surface area of the dust per unit vol of the suspension, and depends on the nature of the salt. Better results are obtained with salts having a mp under 200°. Alkali halides are better than carbonates, potassium better than sodium, fluoride better than iodide and better than chlor-ide. If the dust concentration is high enough, even detonation waves can be extinguished)... 

Methylamine occure in herring brine in crude methyl alcohol from wood distillation, and in the products obtained by the dry distillation of beet molasses residues. It has been prepared synthetically by the action of alkali on methyl cyanate or iso-cyanurate by the action of ammonia on methyl iodide, methyl chloride, methyl nitrate, or dimethyl sulfate by the action of methyl alcohol on ammonium chloride, on the addition compound between zinc chloride and ammonia, or on phos-pham by the action of bromine and alkali on acetamide by the action of sodamide on methyl iodide by the reduction of chloropicrin, of hydrocyanic or of ferrocyanic acid, of hexamethylenetetramine, of nitromethane, or of methyl nitrite by the action of formaldehyde on ammonium chlor-ide.2 ...

Chlor-5-oxy-8-chinoline (18 kg) was mixed with potassium hydroxide (6.0 kg), water (400 kg) and heated. To this solution 50 L saturated aqueous solution of potassium iodide (16.6 kg) was added, mixed and continued to heat. Solution was filtered at room temperature. Then to this yellow solution the solution of chloride of lime and 50 kg 5% solution of were added then all this was mixed and allowed to stand for 24 h. 

Platinic Iodide, Platinum Tetra-iodide, Ptl4, is readily prepared in a variety of ways. It is deposited on addition of hydriodic acid,2 or of sodium (or potassium) iodide 3 to a warm solution of chlor-platinic acid, and allowing to stand at the ordinary temperature. The solution becomes turbid and finally deposits crystals of iodide. 

The iodo-platinates may be prepared by dissolving either platinum tetra-iodide or chlor-platinic acid in aqueous solutions of the iodides of the metals and by neutralisation of the hydroxides of the metals with iodo-platinie acid.

Isomerism of Di-chlor Ethanes.—When, however, we study the constitution of the poly-halogen ethanes we find that isomerism occurs just as in the case of the propyl iodides and of the hydrocarbons above propane. In the case of ethane it is a fact that only one mono-substitution product of any type is known, thereby proving the symmetry of the ethane molecule and the like character of all six of the hydrogen atoms. When two hydrogen atoms are substituted by two chlorine atoms two dif event compounds are produced both having the composition C2H4CI2. From the constitution of the ethane molecule, that has been established by its synthesis from methane (p. 16), we can readily see how this may be explained as we may have two hydrogen atoms replaced by two chlorine atoms in two different ways, as follows ... 

The ethylidene, or unsymmetrical di-halogen substitution products of ethane, are not of much importance, because they do not easily undergo reaction. They are prepared by the reactions just described, viz., from aldehyde by the action of phosphorus penta-chloride, -bromide, or -iodide. Also by the action of phosphorus chlor-bromide, PCl3Br2, or of carbonyl chloride (phosgene), COCI2. They may also be made by the further halogenation of the mono-halogen ethanes ... 

From Ethylene.—The reverse of this reaction takes place when hydracrylic acid is treated with hydrogen iodide, HI, as discussed above in (8). The third synthesis of hydracrylic acid shows its relation to eth dene. Ethylene takes up, by addition, hypochlorous acid, HO—Cl, in just the same way as it does bromine or hydrobromic acid. The compound obtained is glycol chlor hydrine. This chlor hydrine, by treatment with potassium cyanide, is converted into the glycol cyan hydrine. The cyan hydrine, being an acid nitrile, yields an acid on hydrolysis. The acid obtained is hydracrylic acid. 

When malic acid is warmed with phosphorus penta-chloride it yields chlor succinic acid, and when reduced by means of hydrogen iodide, hydrogen is added and succinic acid results. 

Halogen substitution products of the hydrocarbons containing unsaturated side chains are also known, e.g. chlor styrene, CeHs-CH = CHCl, phenyl ethylenyl chloride and iodo phenyl acetylene, CeHs— C = Cl, phenyl acetylenyl iodide.
