toxicity LD50 (mg / kg): acute oral 4,320 rats, rabbits than acute percutaneous 7940. Carp 40th (48h) mg / L, water lice 170mg / L, rainbow trout, catfish greater than 1000 mg / L. Rice, fruit residues of 0.2mg/kg allowed. ADI is kg.
traits: pure white non-volatile solid.
dissolution: 25 ° C in water solubility of 1.2%, generally do not dissolve in organic solvents, isopropylamine salt completely dissolved in water.
use: Low-toxic herbicide, the suction effect - spectrum herbicide, more than 40 Branch have control of the plant, including monocots and dicotyledonous, one year and a perennial, herbaceous plants and shrubs such. The deep roots of perennial weeds in the underground destructive strong agricultural machinery to achieve the general failure to achieve depth. Apply to sugarcane, tea, mulberry, sisal, rubber, timber, and to eliminate Orchard naturally weeding. Right leaf weeds in a uniform directional spray, to avoid the leaves and fruit by the drug. Farmland weeding, rice and wheat, rice and rapeseed crop rotation plots, in the post-harvest stubble down during processing, usually in the day after the spray can direct seeding and transplanting. Liquid water configuration of the water into the mud will reduce efficacy; Three days after the application do not mowing, grazing and soil; Within four hours after the application encountered heavy rain will reduce efficacy, as appropriate, should fill spray; Adding suitable surfactants and diesel, increased efficacy.
preparation or sources: (1) Available an chloroacetic acid, ammonia, phosphorous acid, formaldehyde, concentrated sulfuric acid as raw materials in the system. (2) to chloroacetic acid, ammonia, calcium hydroxide as raw materials, synthetic iminodiacetic acid, and then react with phosphorus trichloride, the provincial food-Gan phosphine, double-Gan phosphine oxide generation glyphosate and oxidant can be concentrated sulfuric acid. (3) glycine, phosphorous acid alkyl ester two more POM for raw materials, the reaction after the saponification, acidification recall after solid glyphosate, the purity of around 95%. Yield 80%.
Note: If skin and eye contact with drugs, with substantial water to wash, rinse time not less than 15 minutes, and asked the doctors.
