Oxamide, H2NCOCONH2, mol wt 80.07, is sparingly soluble in water and insoluble in various organic solvents. It melts at about 350 °C, with accompanying decomposition. Because of the low solubility in water, the compound is granulated and used as a slow-release nitrogen fertilizer.
용도
Oxamide is used as a stabilizer for nitrocellulose preparations. It also finds use in APCP rocket motors as a high performance burn rate suppressant.
정의
ChEBI: A dicarboxylic acid diamide of oxalic acid.
농업용
Oxamide (H2 NCOCONH2 ), a diamide of oxalic acid, is a
white crystalline and non-hygroscopic fertilizer
containing about 32% nitrogen, most of which is waterinsoluble
at 25°C. Oxamide is made from cyanogen
hydrolysis in an acid medium. It releases nitrogen slowly
and hence is used as a slow-release fertilizer. It is
decomposed by soil micro-organisms in the soil.
Safety Profile
Poison by ingestion and intraperitoneal routes. An eye irritant. When heated to decomposition it emits toxic fumes of NOx. See also AMIDES.
Purification Methods
Crystallise oxamide from water, grind it and dry it in an oven at 150o. [Beilstein 2 IV 1860.]
