Diantimony pentoxide Usage And Synthesis
| Chemical Properties | yellow powder |
| Physical properties | Yellow powdery solid; density 3.80 g/ cm3; very slightly soluble in water; hydrated pentoxide is insoluble in nitric acid; dissolves in an aqueous solution of caustic potash. |
| Uses | It is used as flame retardants in acrylonitrile-butadiene-styrene (ABS) polymer, plastics, rubbers, paper and textiles. It finds use as a flocculant in the production of titanium dioxide. It also finds use in ion-exchange resin. It is also employed as catalyst in certain polymerization and oxidation reactions. |
| Uses | Fire retardant in clothing. |
| Uses | Antimony pentoxide (Sb2O3) is used as a flame retardant for textile materials and as a sourceto prepare other antimony compounds. |
| Definition | A yellow solid. It is usuallyformed by the action of concentrated nitricacid on antimony or by the hydrolysis ofantimony(V) chloride. Although an acidicoxide, it is only slightly soluble in water. |
| Preparation | The hydrated oxide is prepared by hydrolysis of antimony pentachloride; or by acidification of potassium hexahydroxoantimonate(V), KSb(OH)6 [12208- 13-8]. The product, filtered and air dried at ambient temperature has approximate composition Sb2O5 ? 3.5H2O. It may be also prepared by oxidation of antimony trioxide with nitric acid. |
| Flammability and Explosibility | Non flammable |
| reaction suitability | core: antimony
reagent type: catalyst |
| Safety Profile | Moderately toxic byintraperitoneal route. See also ANTIMONYCOMPOUNDS. |
