Reactive GroupAmides 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 ReactionsNo rapid reaction with air. No rapid reaction with water.

応用分野
使用Phenylureas are commonly used soil-applied herbicides for control of grass and small-seeded broadleaf weeds.
一般的な説明Phenylurea is the core structural unit of phenylurea herbicides (PUHs), such as diuron, fenuron, linuron, monuron, isoproturon, monolinuron and chlortoluron. As photosynthesis inhibitors, phenylurea herbicides are widely used in various crops for the pre-emergence and post-emergence control of broadleaf and annual weeds. These herbicides are used on major food crops, including maize (Zea mays) and tomato (Solanum lycopersicum), to control weeds such as lamb’s quarters (Chenopodium album), amaranth (Amaranthus spp.) and barnyard grass (Echinochloa crus-galli)[1].
調製方法
製造方法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.
純化方法Crystallise the urea from boiling water (10mL/g) or amyl alcohol (m 149o). Dry it in a steam oven at 100o. The 1:1 resorcinol complex has m 115o (from EtOAc/*C6H6). [Beilstein 12 H 346, 12 II 204, 12 III 760, 12 IV 734.]
