| description | The present invention describes a method of purifying a pesticide that includes: a) melting a pesticide, wherein the pesticide includes at least one active ingredient and at least one impurity capable of inhibiting crystallization; b) coating the pesticide on a substrate to form a pesticide particle; c) substantially reducing the amount of crystallization inhibiting impurity by an azeotropic method; and d) crystallizing the pesticide. In another embodiment, the present invention includes a method of purifying a pesticide as described above, such that the pesticide has a melting point of not more than about 90° C. Also included in the invention is the product produced by the above process for the pesticide, methyl N-(2-{[1-(4-chlorophenyl)-1H-pyrazol-3-yl]oxymethyl}phenyl)N-methoxy carbamate. |
