Chloroplantinic acid Chemical Properties,Usage,Production

Description Chloroplatinic acid is a reddish-brown deliquescent solid. Molecular weight =409.8; Freezing/Meltingpoint =60℃. Hazard Identification (based on NFPA-704 MRating System): Health 2, Flammability 0, Reactivity 0.Soluble in water.
Chemical Properties Chloroplatinic acid is a reddish-brown deliquescent solid
Chemical Properties Orange/Red Crystals
Uses Chloroplatinic acid is used in preparing most platinum salts and complexes. It also is used as an electroplating bath for plating and coating of platinum. Other applications are in catalysis. Catalyst precursor for the reaction of silyl hydrides with olefins, hydrosilylation.Also used for the determination of potassium.
Uses In platinum plating, photography, platinum mirrors, platinum luster on glass and porcelain, platinized carbon for acetic acid manufacture; platinizing pumice stone or asbestos, as catalyst in manufacture of SO3; indelible ink; relief etching of zinc for artistic and commercial purposes; fixing microscopic Preparations, etc.
Uses Chloroplantinic acid (H2PtCl6) is one of the most commercially important compounds of platinum. Its many uses include etching on zinc, making indelible ink, plating, and coloring in fine porcelains and use in photography, in mirrors, and as a catalyst.
Definition chloroplatinic acid: A reddish crystallinecompound, H₂PtCl₆, made bydissolving platinum in aqua regia.
General Description Chloroplatinic acid, is a reddish-brown solid. Chloroplatinic acid is soluble in water and will yield a mildly acidic solution. Chloroplatinic acid may cause illness from inhalation of the dust and Chloroplatinic acid is irritating to skin and eyes. When heated to high temperatures Chloroplatinic acid may decompose to toxic chloride fumes. Chloroplatinic acid may burn, but may be difficult to ignite. Chloroplatinic acid is used for manufacturing indelible ink and in electroplating processes.
Air & Water Reactions Soluble in water.
Reactivity Profile Oxidizing acids are generally soluble in water with the release of hydrogen ions. The resulting solutions have pH's of less than 7.0. Materials in this group react with chemical bases (for example: amines and inorganic hydroxides) to form salts. These neutralization reactions occur as the base accepts hydrogen ions that the acid donates. Neutralizations can generate dangerously large amounts of heat in small spaces. The dissolution of acids in water or the dilution of their concentrated solutions with water may generate significant heat. The addition of water acids often generates sufficient heat in the small region of mixing to boil some of the water explosively. The resulting "bumping" spatters acid widely. These materials have significant ability as oxidizing agents. but that ability varies (for example, from high for nitric acid to low for sulfuric acid and most sulfonic acids). They can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Like other acids, materials in this group can initiate polymerization in certain classes of organic compounds. Their reactions with cyanide salts and compounds release gaseous hydrogen cyanide. Flammable and/or toxic gases are also often generated by their reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Acids often catalyze (increase the rate) of chemical reactions.
Health Hazard TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Flammability and Explosibility Non flammable
reaction suitability core: platinum
reagent type: catalyst
Safety Profile Poison by intravenous and intraperitoneal routes. Mutation data reported. See PLATINUM COMPOUNDS and CHLORIDES. Incompatible with BrF3. When heated to decomposition it emits toxic fumes of Cl-.
Potential Exposure Chloroplatinic acid has many uses, among them are platinum plating, photography, and catalysis.
First aid If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water ormilk. Do not induce vomiting.
storage Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Store intightly closed containers in a cool, well-ventilated area
Shipping UN2507 Chloroplatinic acid, solid, Hazard class: 8; Labels: 8-Corrosive material.
Purification Methods If it is to be purified, or regenerated from Pt recovered from catalytic hydrogenations, it should be dissolved in aqua regia followed by evaporation to dryness and dissolution in the minimum volume of H2O. Then the aqueous solution is treated with saturated ammonium chloride until all the ammonium hexachloroplatinate separates. The (NH4)2PtCl6 is filtered off and dried at 100o. Igniting this salt gives Pt sponge; dissolve the Pt sponge in aqua regia, boil to dryness, dissolve the residue in concentrated HCl, boil to dryness again and repeat the process. Protect it from light. [Hickers J Am Chem Soc 43 1268 1921, Adams et al. Org Synth Coll Vol I 463, 466 1941, Bruce J Am Chem Soc 58 687 1936.]
