a white crystal having a melting point of 175 to 177 ° C. And a vapor pressure (20 ° C.) of 4.0 × 10-s Pa. Solubility at 25 C: methanol 1.8%, chloroform 5.2%, water 33mg/L. It is stable in slightly acidic and slightly basic media, but at high temperatures, alkali and inorganic acids can hydrolyze it to non-herbicidally active hydroxyl derivatives. Non-corrosive.
with cyanuric chloride as raw material, after mixing cyanuric chloride with solvent, it first reacts with ethylamine, then reacts with isopropylamine, and then obtains atrazine raw powder by separation, drying and other processing.
is a selective pre and post seedling herbicide. Root absorption, stem and leaf absorption is very little, rapid conduction to the plant meristem and leaf, interference with photosynthesis, so that weeds die. In resistant crops such as corn, it is decomposed by the enzyme to produce non-toxic substances, which is safe for crops. Atrazine water-soluble, mobility in the soil is greater than simazine, easy to be leached by rain to the deeper layer, can inhibit some deep-rooted weeds, in the soil can be decomposed by microorganisms. Suitable for corn, sorghum, woodland, grassland, sugarcane and other annual and biennial broad-leaved weeds and monocotyledon weeds.
The oral LD50 was 3080mg/kg in rats, 1750mg/kg in mice, and 7500mg/kg in rabbits. The rats were fed with feed containing 1000mg/kg for 2 years, and no abnormality was found. Teratogenic and carcinogenic test was negative. Low toxicity to birds and fish. No irritation to the eyes, slight irritation to the skin.
