5-NITROBARBITURIC ACID(Cas 480-68-2) Usage
|
synthesis |
5-Nitrobarbituric acid can be obtained by nitration of barbituric acid with fuming nitric acid below 40°C with a yield of 85-90%. |
|
Purification Methods |
Crystallise diliuric acid from water as the trihydrate (m 180-181o (dec). Drying over 70% H2SO4 converts the trihydrate to the dihydrate [Loeffler & Moore J Am Chem Soc 70 3650 1948]. [Beilstein 24 H 474, 24 II 273, 24 III/IV 1882.] |
