Embodiment 1
[0028] Embodiment 1 of the present invention: the organic compound of preventing and treating plant virus, its chemical structural formula is:
[0029] Its concrete synthetic steps are as follows:
[0030] (1) Synthesis of 1-aminocyclohexanenitrile oxalate (a)
[0031] Add 2.0g (0.041mol) of sodium cyanide and 10mL of water into the reaction flask equipped with mechanical stirring and reflux condenser, keep stirring, and after the sodium cyanide is completely dissolved, add 2.3g (0.043mol) of ammonium chloride Aqueous solution (10mL), 20% ammonia water (4mL) and methanol (10mL) solution of 3.0g (0.032mol) cyclohexanone, stirred at room temperature for 1.5h, heated to 60°C and stirred for 45min, stopped heating, and continued stirring for 45min; cooled to Extract with dichloromethane (15mL×6) at 25°C, dry the organic phase with anhydrous magnesium sulfate, filter, concentrate the filtrate, dissolve the remaining oil (4.1g) in 25mL acetone, add 3.0g (0.033mol ) in acetone (2...
Embodiment 2
[0045]Embodiment 2 of the present invention: get the prepared compound d 25kg in embodiment 1, formaldehyde condensation polymer with naphthalene sulfonic acid 10 kg, sodium methylene bissulfonic acid 4.5 kg, sodium methylnaphthalene sulfonate 6 kg , 10 kg of white carbon black, 0.2 kg of xanthan gum and 0.1 kg of defoamer (organic silicon) are mixed, and water is added to make up to 100 kg, and the above raw materials are added to the shearing tank, and the shearing tank is opened, and sheared for 30 minutes Mix the materials evenly, then turn on the circulating water, ball mill the materials at a certain flow rate, the temperature is controlled below 40 degrees, and the fineness passes through a 325 mesh sieve. After grinding for 1.5 hours, a uniform milky liquid is obtained, which is the suspending agent.
Embodiment 3
[0046] Embodiment 3 of the present invention: get the prepared compound d 50kg in embodiment 1, and naphthalenesulfonic acid formaldehyde polycondensation product 12kg, methylenebisketal sodium sulfonate 1 kg, methylnaphthalene sodium sulfonate 3kg and white Mix 20 kg of carbon black, and add kaolin to make up to 100 kg, add the above raw materials into a double-screw mixer, mix and stir, then pulverize through a jet mill, pass through a 325 mesh sieve, and then mix through a double-screw mixer to obtain the product, namely It is a wettable powder.
[0047] In addition to the suspending agent prepared in Example 2 and the wettable powder prepared in Example 3, the compound of the present invention and other pesticide-acceptable adjuvants, surfactants, solvents and carriers can also be prepared in a conventional manner Soluble liquid, microemulsion, water emulsion, seed coating, wettable powder, sustained release granule, controlled release granule, water dispersible granule, d...
