| Reaktive Gruppe | Amides and Imides |
| Reactivity Profile | Organic 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). Contains any of several related compounds (Diuron, Fenuron, Linuron, Neburon, Siduron, Monuron) formally derived from urea. |
| Air and Water Reactions | No rapid reaction with air. No rapid reaction with water. |

Anwendungen & Verwendung
Verwenden
Phenylureas are commonly used soil-applied herbicides for control of grass and small-seeded broadleaf weeds.
Herstellung & Synthese
synthetische
Phenylurea is synthesized by the reaction of aniline and urea. Put urea, hydrochloric acid and aniline into the reaction pot, heat and stir, reflux at 100-104°C for 1 hour, add water and stir, cool, filter, wash the filter cake with water, and dry to obtain the finished product of phenylurea.
