| Diantimony trioxide Usage And Synthesis |
| Antimony oxides |
Antimony trioxide, together antimony tetroxide and antimony pentoxide, are the current three compounds forming between antimony and oxygen with industrial application. Antimony can form a series of oxide with oxygen such as Sb2O3, Sb2O4, Sb2O5, Sb6O13, and Sb2O as well as gaseous SbO. However, only the first three compounds have significance in industrial production with other oxides mostly being the transition product of various kinds of antimony production process. Antimony trioxide (Sb2O3, Mr291.50) is a dual-type substance including cubic crystal and monoclinic crystal type. For different crystal form, the density and refractive index also slightly differ. The density and refractive index of cubic crystal is 5.2 and 2.087, respectively while is 5.67 and 2.18 for the monoclinic crystal, respectively. The Sb2O3 commonly derived from hydrolysis of SbCl3 is rhombic crystal can burn to red heat in an inert gas or in vacuum and can generate square crystal upon sublimation. Antimony trioxide is a kind of white powder with the density being 5.67g / cm3. It becomes yellow when being heated and turn back to white upon being cooled. Upon 656 ℃, it can be molten into yellow or gray liquid with becoming white asbestos-like mercerizing substance. Antimony trioxide is slightly soluble in water, ethanol and dilute acid, easily soluble in concentrated hydrochloric acid, oxalic acid and tartaric acid, and is also soluble in fuming nitric acid and fuming sulfuric acid; it form antimonite upon be dissolved in alkali. Antimony trioxide has a low toxicity but has irritation effect on nose, eyes, throat and respiratory tract. Skin contact may induce dermatitis. Antimony trioxide mainly has two preparation methods including dry and wet. Dry method is through reducing the crude sulfur trioxide generated from the calcined sulfantimonide ore into metallic antimony in the presence of coke with soda as the melting promoting agent. The wet method is through leaching sulfur antimony ore with hydrochloric acid to generate antimony trichloride and further hydrolysis with caustic soda to obtain it. Figure 1 the two crystal types of antimony trioxide |
| Flame retardant |
Antimony trioxide is a widely used flame retardant suitable to being used for polyethylene, polystyrene, polyvinyl chloride, polyester, epoxy resin, polyurethane and other plastics. However, it has low flame retardant effect when being used alone. Instead it has good synergistic effect when being used in combination with phosphates, chlorine-containing compounds (such as chlorinated paraffins, PCBs, perchloro-glutar-cyclodecane etc.), bromine-containing compounds (such as Hexabromobiphenyl, Hexabromobenzene) with the flame retardant performance being improved significantly. Combining of antimony trioxide with chloride or bromide can result in antimony trichloride or antimony bromide which is reactive and volatile substances which can promote the halogen movement and generation of carbides in its solid form as well as capturing free radicals in its gas form. These reactions can all contribute to flame retardancy. It is always combined with zinc oxide, sodium hydroxide, etc. to be used as brominated synergist flame retardant synergist for being applied to plastic fire prevention system. Antimony trioxide can also be used in the manufacture of antimony potassium tartrate, pigments, porcelain enamels, dyes and other media. It can also be used as a catalyst for polyester poly-condensation. Figure 2 the reference quality standard of superior grade of antimony trioxide |
| Preparation of antimony trioxide from antimony potassium tartrate |
Add the ammonia into the boiling liquid of antimony potassium (one part of antimony potassium tartrate K (SbO) C4H4O6 is dissolved in 10 parts of water); boil for a period of time, filtered, wash to give antimony trioxide. Among them, only trace amounts of silicon, magnesium has been detected from the antimony trioxide generated from the hydrolysis method through spectroscopy qualitative analysis. It is suitable as spectral analysis standard. Add 15 g of analytic purity grade antimony trioxide to the 500 mL beaker, further add 30ml of high purity hydrochloric acid (1 + 1), and dissolve it under stirring. Filter the solution with washed sand glass funnel to remove insoluble impurities. Further dilute it to 400 mL with high purity water when white chlorine oxide antimony is precipitated. Once the solution becomes clear, decant the supernatant liquid and wash the precipitate through decantation for several times. To the washed precipitate, add 200 mL of high-purity ammonia (1 + 25) and boil for 5 ~ 10min, when the antimony oxychloride all becomes antimony trioxide. The generated antimony trioxide particle is much smaller than the antimony oxychloride. Pour out the clearing solution and boil again for several times using the same method in dilute ammonia. Check the washed solution with silver nitrate; when the poured liquid no longer contains chlorine ions, all the antimony oxychloride has been completely converted to antimony trioxide. Then use high-purity water decantation for wash the precipitate for several times. Use Buchner funnel for filtration and then wash the precipitate with high purity water until the washed liquid becomes neutral again. The washed precipitate is dried in an oven at 150 ℃ to constant weight; take it out after cooling to get the final product of antimony trioxide.

| Toxicity |
Acute poisoning manifested as stimulation of the respiratory tract, gastrointestinal tract and skin. Chronic poisoning can affect metabolism, cause dry skin, chapped fingers and perinasal and can also cause allergic diseases (eczema, urticaria). Upon poisoning through the respiratory tract, we can give a lot of sweet tea or coffee drinks, aspirin, amino-pyrazole morpholino for treatment. Upon poisoning caused by swallowing dust, you can tannic acid solution, protein water for repeatedly washing stomach, taking warm milk and mucus drinks (pearl barley soup). Maximal allowable concentration in air is 1 mg/m3. Use protective equipment during operation. Prevent dust formation and release into the air of workplace.
