Storage method

Keep sealed.

Synthesis method

1. Obtained from the reaction of triazine cyanide and ethylamine in the presence of acid acceptor. If water is used as the reaction medium, add the material at about 0°C, then keep stirring at 70°C for 2 hours. If the reaction is carried out in a solvent such as trichlorethylene, the reaction temperature is 30-50°C. Raw material consumption quota: cyanuric chloride (96%) 1020kg/t, monoethylamine (100%) 520kg/t, liquid caustic soda (40%) 100kg/t, trichlorethylene (industrial product) 120kg/t.

2.Use water as the reaction medium, mix cyanuric chloride and ethylamine at about 0℃ in the presence of acid binding agent, and then Prepared by 70°C insulation reaction for 2 hours.

Purpose

1. This product is a highly efficient and selective herbicide, mostly used to control annual and perennial broadleaf weeds and most monocotyledonous weeds propagated by seeds in corn, sorghum, sugarcane, tea gardens, orchards, etc. It can also be used on railways , highways, oil fields and biocidal weeding. Pesticide residue analysis standards. herbicide.

2.S-triazine herbicides. It is easily adsorbed on the surface of the soil, forming a poisonous soil layer. The roots of shallow-rooted weed seedlings absorb the pesticide and are killed. Less effective on perennial or deep-rooted weeds with deeper root systems. Used to control annual or perennial broadleaf weeds and most monocotyledonous weeds propagated by seeds in corn, sugar cane, sorghum, tea trees, rubber, orchards and nurseries; it can significantly inhibit perennial weeds propagated by rhizomes or root buds. Effect; appropriately increase the dose and can also be used as a biocidal herbicide on forest fire roads, along railway roadbeds, courtyards, warehouse storage areas, oil tank areas, lumberyards, etc.
