| Oxamide Usage And Synthesis |
| Chemical Properties | white fine crystalline powder | | Chemical Properties | 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. | | Uses | Oxamide is used as a stabilizer for nitrocellulose preparations. It also finds use in APCP rocket motors as a high performance burn rate suppressant. | | Definition | ChEBI: A dicarboxylic acid diamide of oxalic acid. | | Agricultural Uses | 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.] |
