Embodiment 1
[0024] Add 1.25 g of phorbol esters of Jatropha curcas with a purity of 80% into 5 g of ethanol and 5 g of glycerol, stir at room temperature to fully dissolve the phorbol esters, and obtain a homogeneous oil phase mixture; dissolve 3 g of calcium alkylsulfonate in 30ml of water, and then add 2g of pyrogallic acid, 2g of glycerin, 0.1g of polyoxyethylene oxypropylene glycerin, 2g of polyvinyl alcohol, and 0.1g of acetic acid into the aqueous solution, and stir to make it fully dissolve to obtain a homogeneous aqueous phase mixture; Then, add the obtained water phase mixture into the oil phase mixture, then stir for 20 minutes at a rotating speed of 10000r / min, and add the remaining 49.55ml of water at the same time to form the oil-in-water type phorbol jatropha ester Insecticidal water emulsion.
Embodiment 2
[0026] Add 1.25 g of phorbol ester of Jatropha curcas with a purity of 80% into 5 g of ethanol, 10 g of cyclohexanone, 2 g of toluene, and 3 g of dimethyl sulfoxide, and stir at room temperature to fully dissolve the phorbol ester to obtain a homogeneous oil phase mixture; Dissolve 3g of fatty alcohol polyoxyethylene ether phosphate and 5g of alkylphenol polyoxyethylene ether formaldehyde condensate in 30ml of water, and then add 15g of disodium hydrogen phosphate, 5g of urea, and 0.1g of polyoxyethylene oxypropylene into the aqueous solution Glycerin, 2g polyvinyl alcohol, 0.2g sodium hydroxide, stir to make it fully dissolve to obtain a homogeneous water phase mixture; at room temperature, add the obtained water phase mixture to the oil phase mixture, and then at a speed of 11000r / min, Stir for 10 minutes, and add the remaining 18.45ml of water at the same time to form an oil-in-water type phorbol jatropha insecticidal emulsion in water.
Embodiment 3
[0028] Add 5.88 g of phorbol esters of Jatropha curcas with a purity of 85% into 5 g of isopropanol, 5 g of cyclohexanone and 10 g of n-octanol, stir at room temperature to fully dissolve the phorbol esters, and obtain a homogeneous oil phase mixture; Alcohol polyoxyethylene ether phosphate is first dissolved in 30ml of water, then add 10g of borax, 3g of ammonium sulfate, 0.2g of polyoxyethylene oxypropylene glycerin, 1.5g of xanthan gum, and 0.1g of sodium hydroxide to the aqueous solution, and stir to make it Fully dissolve to obtain a homogeneous water phase mixture; at room temperature, add the obtained water phase mixture to the oil phase mixture, then stir for 20 minutes at a speed of 10000r / min, and add the remaining 4.32ml of water at the same time to form a water phase mixture. Oil-in-oil type jatropha phorbol ester insecticidal aqueous emulsion.
