Basic Info
Model No.: X-CAS 99129-21-2
Product Description
Herbicide CAS 99129-21-2 Clethodim
Application: Post-emergence herbicide, stem-leaf treatment with high selectivity and systemic uptake. It is used to control many kinds of annual and multiple grass weeds. For annual grass weeds 3 to 5 leaf stage application, perennial grass weeds should be applied after splitting. Such as soybean, peanut, rape, cotton, flax, tobacco, a variety of broad-leaved vegetables, grapes, oranges, apples and other plantations, can be applied to the grass from the second leaf to the tillering stage. It is used to control annual weeds such as barnyardgrass, wild oats, green foxtail, crabgrass, goosegrass, aphrodisiac, coriander, millet, etc., and appropriately increase the dosage to control perennial weeds such as imperata, arabian sorghum and bermudagrass And some highly resistant annual grass weeds. For soybean field weeding with 24% EC 408 ~ 600mL/hm2, spray on water stems and leaves. If medication is not applied during the best application period, increase the number of applications or increase the amount of medication. Selective herbicides control annual and perennial grass weeds.
Production method
( 1 ) introducing hydrogen chloride gas from the bottom of a turbulent absorption tower by a gas-liquid phase synthesis method, contacting with circulating mother liquor sprayed at the top of the tower to generate saturated ammonium chloride mother liquor which flows into a reactor, and carrying out neutralization reaction with the introduced ammonia gas to generate ammonium chloride saturated solution. Sending to a cooling crystallizer, cooling to 30 - 45 deg c, and separating out supersaturated ammonium chloride crystals. Sen ammonium chloride solution at that upper part of the crystallizer to an air cool for cooling and circulating to the crystallizer; The lower crystal pulp is thickened by a thickening device and then centrifugally separated to prepare an ammonium chloride finished product. The reaction equation is as follows: centrifugally separated mother liquor is sent to a turbulent absorption tower for recycling.
2. the metathesis method comprises the following steps: firstly, adding ammonium chloride mother liquor into a reactor to be heated to 105 deg c, adding ammonium sulfate and salt, carrying out metathesis reaction at 117 deg c to generate ammonium chloride solution and sodium sulfate crystals, filtering and separating to remove sodium sulfate, sending the saturated ammonium chloride solution to a cooling crystallizer, cooling to 32 - 35 deg c to separate out crystals, filtering, respectively leaching the crystals with ammonium chloride solutions with four different concentrations ( 15 - 17 deg b é, 11 - 12 deg b é, 10 deg b é, 9.5 - 10 deg b é ), controlling Fe < 0.008 %, so42 - 0.001 %, and leaching until the crystals are qualified The reaction equation is as follow: that mother liquor is sent to a metathesis reactor for recycle. Sodium sulfate separated by filtration was used to produce sodium sulfate.
3. adding crude ammonium chloride into a dissolver by recrystallization, introducing human steam to dissolve, filtering, cooling and crystallizing the filtrate, centrifugally separating and drying to obtain the finished product of industrial ammonium chloride. The centrifugally separated mother liquor is returned to the dissolver for use. Adding industrial ammonium chloride into a dissolver filled with distilled water by recrystallization method, dissolving the dissolver by heating, adding arsenic removing agent and heavy metal removing agent, purifying the solution, filtering, removing impurities such as arsenic and heavy metal, cooling and crystallizing the filtrate, centrifugally separating, and drying to obtain the finished product of edible ammonium chloride. ...
