| Hazard Information | Back Directory | [General Description]
Odorless white solid. | [Reactivity Profile]
N-BUTYLUREA(592-31-4) is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). This compound decomposes on heating. | [Air & Water Reactions]
Water soluble. | [Health Hazard]
ACUTE/CHRONIC HAZARDS: This compound emits toxic fumes when heated to decomposition. | [Fire Hazard]
Flash point data for this chemical are not available. N-BUTYLUREA is probably combustible. | [Chemical Properties]
WHITE TO ALMOST WHITE CRYSTALLINE POWDER | [Uses]
n-Butylurea is used as a fertilizer for rice. It is used in the preparation of drugs which are recommended for diabetes. | [Purification Methods]
Crystallise the urea from pKEst EtOH/water, then dry it under vacuum at room temperature. [Beilstein 4 I 371, 4 IV 578.] |
