Chemische Eigenschaften

Colorless needle-like crystals or off-white powder. Melting point 147°C(decomposition), soluble in hot water, hot alcohol, ether, ethyl acetate and acetic acid.

Verwenden

Phenylureas are commonly used soil-applied herbicides for control of grass and small-seeded broadleaf weeds.

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.

Application

Phenyl urea pesticide, liquid, poisonous appears as a liquid dissolved or suspended in a liquid carrier. Contains any of several related compounds (Diuron, Fenuron, Linuron, Neburon, Siduron, Monuron) formally derived from urea. Carrier is water emulsifiable. Toxic by inhalation, skin absorption, or ingestion.

Allgemeine Beschreibung

A solid or liquid absorbed on a dry carrier. A wettable powder. Contains any of several related products (Diuron, Fenuron, Linuron, Monuron, Neburon, Siduron) formally derived from urea. Toxic by inhalation, skin absorption, or ingestion. Obtain the technical name of the specific pesticide from the shipping papers and contact CHEMTREC, 800-424-9300 for response information.

Reaktivität anzeigen

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.

Health Hazard

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Brandgefahr

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.

läuterung methode

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.]
