Embodiment 1
[0052] The epoxy camellia oil monomer ECO-NH and the epoxy camellia oil monomer ECO in the present invention are the second epoxy camellia oil monomer and the first epoxy tea oil monomer disclosed in the Chinese patent application document with publication number CN113214433A, respectively. Monomer; it is prepared according to the following process:
[0053] (1) prepare epoxy camellia oil monomer ECO-NH, and its preparation route is as follows:
[0054]
[0055] Preparation of camellia oil precursor: Weigh 100 g of camellia oil, add it to a 250 mL round-bottomed flask, and pour N into an oil bath at 100 °C. 2 After blowing for 1 hour, reduce the temperature to 60°C, add 33.2g of ethanolamine and 1.5mL of sodium methoxide, and react for 4h; then add 400mL of dichloromethane solution and mix well, pour the mixed solution into a separatory funnel, and then add The saturated NaCl solution was washed and repeated three times, and the dichloromethane layer solution was collected...
Embodiment 2
[0067] Measure 1000 μL of the epoxy camellia oil monomer ECO in Example 1 and add it to the ampoule, add 105.5 mg of PEG in Example 1 4k -CTA, then add 2255μL of ethanol and 1722μL of pure water to dissolve; make azobisisobutylimidazoline hydrochloride VA-044 into a 5mg / mL aqueous solution, add 533μL to the ampoule bottle, and seal the ampoule bottle. After three freeze-thaw cycles, the mixed solution was charged with nitrogen and reacted at 70 °C for 2 h to obtain pure PECO polymer.
[0068] Take 2.5 mL of the prepared pure PECO polymer liquid; weigh 70.9 mg of emamectin powder with a mass fraction of 70.5%, and mix it with 2.5 mL of a mixed solution of ethanol and water, wherein the volume ratio of ethanol to water is 1 : 1, then add it into the pure PECO polymer liquid and mix evenly to obtain the emamectin salt preparation.
Embodiment 3
[0070] Measure 900 μL of the epoxy camellia oil monomer ECO in Example 1 and 99 mg of the epoxy camellia oil monomer ECO-NH in Example 1 into the ampoule, add 105.5 mg of PEG in Example 1 4k -CTA, then add 2250 μL of ethanol and 1717 μL of pure water to dissolve; make azobisisobutylimidazoline hydrochloride VA-044 into a 5 mg / mL aqueous solution, add 533 μL to the ampoule bottle, and seal the ampoule bottle. After three freeze-thaw cycles, the mixed solution was charged with nitrogen and reacted at 70° C. for 2 h to obtain a polymer with a monomer ECO:ECO-NH molar ratio=9:1.
[0071] Take 2.5 mL of the prepared polymer liquid; weigh 70.9 mg of emamectin powder with a mass fraction of 70.5%, and mix it with 2.5 mL of a mixed solution of ethanol and water, wherein the volume ratio of ethanol to water is 1:1 , and then added into the polymer liquid and mixed uniformly to obtain the emamectin salt preparation.
