pure white crystals. Melting point 163~164.5 ℃ (original 155 ℃), relative density (20 ℃)1. 39, vapor pressure (20 ℃)6.65 × 10-s Pa. 25 ° C water solubility of 80 x 10-6, soluble in acetone, ethanol and other organic solvents. It is easy to decompose in case of strong acid and alkali.
with a trifluoromethyl aniline, phosgene, two as raw materials. Using toluene as solvent, phosgene and meta-trifluoromethylaniline were reacted at room temperature to generate isocyanate. The subsequent addition of isocyanate with dimethylamine gives the result of the vortazone.
It is an early herbicide with internal absorption conduction type, which is substituted for urea herbicide. The control of cotton, corn and other crops in the field of annual weeds effect is outstanding. For cotton, corn, sugar cane, fruit tree control of annual grass weeds and broad-leaved grass, such as humulus scandens, crickets, Kentucky bluegrass, Maldon, bitter vegetables, Cyperus papyrifera, dampenia, amaranth, dog tail grass, purslane, gold, etc.
The oral LD50 of rats was 8900mg/kg. Rats were fed at a dose of 100mg/kg per day. 180 days later, no toxic symptoms were observed. Rats fed for 2 years test no effect of the dose of 30mg/kg, mice 10mg/kg, animal test no teratogenic, carcinogenic, mutagenic effect, reproductive test also found no abnormalities. Rainbow trout LC50 47mg/L(96H), carp LC50 170mg/L. Bee LD50 is 193VG/, low toxicity to birds. Slightly irritating to the eyes and skin.
