Problems solved by technology
If the pH value is too high or too low, or if the moisture content is too high, its stability will be reduced
Although the original drug of triazophos on the market has been added with a stabilizer, because the stabilizer produces a corresponding acid during storage, such as acetic anhydride will react with water to generate acetic acid during storage, and the latter can catalyze the decomposition of triazophos Hydrolysis, reducing the stability of triazophos

Embodiment Construction
[0017] Below in conjunction with example the present invention is further described.
[0018] Such as figure 1 As shown, the present invention is a kind of triazophos former drug floating stabilization bag with molecular sieve as adsorbent, and its structure is to make stabilization bag 1 with mesh material, and the molecular sieve 2 after activation is wrapped in stabilization bag 1, and stabilization bag 1 is connected with the float 5, and the buoyancy of the float 5 keeps the stable bag 1 on the upper layer of the triazophos former medicine 4. The activated molecular sieve 2 described in the stabilizing bag 1 can have a pore size of 3 to 8 angstroms, and the optimum pore size is 4 to 6 angstroms. The mesh material in the present invention includes but not limited to silk mesh, non-woven fabric or gauze composed of polymer materials. Float 4 of the present invention includes but not limited to plastic float, bamboo, cork float, wherein is the best with plastic float. The...

The invention relates to a triazophos technical toxicant floatation stabilizing pocket using a molecular sieve as an adsorbent, which comprises a stabilizing pocket made of a net material, wherein an activated molecular sieve is wrapped in the stabilizing pocket; the periphery of the stabilizing pocket is connected with a buoy; and the buoyancy of the buoy can keep the triazophos technical toxicant at the upper layer of the stabilizing pocket. The triazophos is floated on the upper layer of the stabilizing pocket, so that the water, ethanol, O,O-ethylphosphorus thiodichloride and the like on the upper part of the triazophos technical toxicant in the barrel can be sufficiently and quickly absorbed, thereby effectively removing impurities in the triazophos technical toxicant, preventing the triazophos from hydrolysis and alcoholysis and obviously enhancing the stability of the triazophos technical toxicant.
Description
technical field [0001] The invention relates to a device for improving product stability, in particular to a floating stable bag of triazophos original medicine with molecular sieve as an adsorbent. Background technique [0002] Triazophos, chemical name: O, O-diethyl-O-(1-phenyl-1,2,4-triazol-3-yl) phosphorothioate. The pure product is a light brown liquid with a melting point of 0-5°C, a specific gravity of 1.247, a vapor pressure of 0.387MPa at 30°C, and a solubility in water of 35mg / L at 20°C; it is soluble in most organic solvents. Stable to light, hydrolyzed in acid and alkali medium, decomposed at 140℃. Triazophos is a broad-spectrum insecticide and nematicide. It has contact killing and stomach poisoning effects on pests, strong permeability, and obvious ovicidal effect. It is widely used in the control of major pests of rice, cotton, wheat, corn, vegetables and fruit trees, and has good control effect against resistant cotton bollworm and spider mite. However, t...
