|---|---|
| 颜色 / 形态 : | White or brown orthorhombic crystals；Orthorhombic crystals or white granules；Brownish gray to white crystals according to degree of purity |
| 气味 : | Odorless |
| 熔点 : | 280 °C (decomposes) |
| 溶解性 : | Freely soluble in water, insoluble in ethanol；In water, 76.4 g/100 g water at 25 °C；In water: g ammonium sulfate/100 g saturated solution: 41.22 at 0 °C; 43.47 at 25 °C; 50.42 at 100 °C；In water (g/100 g H2O): 70.6 at 0 °C; 76.7 at 25 °C; 103.8 at 100 °C；Insoluble in acetone, ethanol；Solubility decreases with addition of ammonia: at 10 °C, from 73 g in 100 g of water, to 18 g in 100 g of 24.5% aqueous ammonia |
| 密度 : | 1.78 at 59 °F (USCG, 1999) - Denser than water; will sink；1.77 g/cu cm；1.77 @25 °C |
| 蒸气压 : | Vapor pressure of saturated solution: 0.901 kPa at 10 °C; 1.319 kPa at 15 °C; 1.871 kPa at 20 °C; 2.573 kPa at 25 °C; 3.439 kPa at 30 °C; 4.474 kPa at 35 °C |
