实验性质
| 外观 / 形态 : | COLOURLESS HYGROSCOPIC DELIQUESCENT CRYSTALS.；Crystalline solid.；Cyanamide appears as colorless deliquescent crystals. Mp: 45 °C; bp: 260 °C. Density: 1.282 g cm-3. Quite soluble in water (77 g / 100 g solution at 15 °C). Soluble in butanol, methyl ethyl ketone, ethyl acetate, alcohols, phenols, amines, ethers. Note: The term "cyanamide" is also used to refer to the important compound calcium cyanamide, which is a different chemical.；Deliquescent, crystalline solid; [CHEMINFO]；Dry Powder |

| 溶解性 : | In butanol 28.8; ethyl acetate 42.4, methyl ethyl ketone 50.5 (all g/100 g at 20 °C); sol in phenols, amines, ethers, ketones; very sparingly soluble in benzene, halogenated hydrocarbons; practically insoluble in cyclohexane.；Slightly soluble in carbon disulfide；Cyanamide is completely soluble in water at 43 °C and has a minimum solubility at -15 °C; highly soluble in polar organic solvents, such as alcohols, ethers, esters, nitriles and amides, but less soluble in nonpolar solvents like saturated, halogenated, or aromatic hydrocarbons. Ketones are not recommended as solvents for cyanamide, because they tend to react under certain circumstances.；In chloroform 2.4 g/kg, 20 °C；For more Solubility (Complete) data for Cyanamide (7 total), please visit the HSDB record page. |
