If technical grade chlorantraniliprole and technical grade emamectin benzoate are accidentally mixed together, how can they be separated?
What specific substance is it? How large is it?
It’s relatively easy to process, but imidacloprid needs to be dissolved using a dissolution method; chlorantraniliprole is then filtered out and removed, followed by drying. Imidacloprid is concentrated and recrystallized, after which it is washed and dried

But no matter how it is separated, residues of one product will remain in another, failing to meet the quality standards of the original product
Emamectin benzoate and chlorantraniliprole can be dissolved in a solvent; both dissolve. It’s not that simple.
