| introduction | stannous oxide chemical formula SnO, soluble in acid and alkali, slightly soluble in NH4Cl, insoluble in dilute alkali, ammonia and water. Reduced to metal by heating in hydrogen. It is heated and oxidized to tin oxide (Ⅳ) in air. It reacts with Cl2 to produce tin chloride (Ⅳ). Oxidation with nitric acid produces H2SnO3. |
| Application | Tin oxide has reducibility and can be used as a reducing agent to prepare stannous salt. Stannous hydroxide Sn(OH)2 is generated by the reaction of stannous salt solution with sodium hydroxide solution, and then thermally decomposed to generate stannous oxide. |
| preparation method | add ammonia or alkali solution to stannous chloride aqueous solution until phenolphthalein changes color, heat and boil to obtain precipitation, which is obtained by drying under isolated air. |
| synthesis method | 360g of crystalline stannous chloride and 300ml of water are added to dissolve, the reaction bottle is added to 2L four-port reaction bottle, the reaction bottle is placed on an electric heating sleeve, and 20% sodium carbonate solution is added to neutralize under stirring conditions. when the pH value reaches 6, the sodium carbonate solution is stopped, the material is heated, and 12% sodium hydroxide solution is added under stirring, adjust the pH value to 12, the material is heated to boiling, converted, kept slightly boiling for 1h, washed the material, removed Cr, added 1.5ml of antioxidant cresol sulfonic acid, filtered and dried to obtain 213g of stannous oxide product with the main content of 99.18%, Cr:0.016%. When the product is dissolved in 30% methyl sulfonate solution, the solution is colorless and transparent, NTU is 21. |
| Use | Used for the preparation of catalysts, reducing agents, stannous salts Used as a reducing agent, also used for the preparation of stannous salts Used for catalysts, reducing agents. It is also used in electroplating and glass industry. |
| production method | 1. dissolve stannous chloride dihydrate with as little hot concentrated hydrochloric acid as possible. Slowly add sodium carbonate aqueous solution under stirring. Because CO2 gas is generated, attention must be paid to the addition speed. When the mixed solution is shown to be alkaline by phenolphthalein test, the addition is stopped. After heating for 2~3h, the colorless hydrated oxide is quantitatively converted into blue-black SnO with metallic luster. The product was washed several times with water and dried at 110 ℃. The yield is about 80%. 2. Dissolve 30g of high purity tin in hydrochloric acid solution of 120mL 6mol · L-1, and add 200mL of concentrated ammonia water under stirring to generate white precipitate. At this time, the pH value of the solution rises to 9. The precipitate was washed three times with 2mol/L ammonia water by pouring method. Add 50mL 2mol/L ammonia water to the precipitate to maintain the temperature of 60~70 ℃ overnight. The white precipitate is transformed into a black crystalline product, filtered, washed 10 times with deionized water, and dried at 90°C. About 30g of pure black SnO can be obtained. Using the same reagent, changing certain conditions such as pH value can also make red SnO[407]. |
