IMPROVED SYNTHESIZING METHOD OF HALOFORMIMINE COMPOUND

PURPOSE: The improved method for producing the haloformimine compound having excellent purity with high yield rate by responding the formimine compound and halogen agent in a solvent as maintaining pH to be 2¯5 of halogen reaction. CONSTITUTION: The synthesizing method of haloformimine compound has the steps of: mixing formimine compound with the base enough to provide the mixture of pH 2¯5 and a solvent; responding with halogen agent as maintaining the formimine compound of the pH to be 2¯5 to produce the haloformimine compound. The halogen agent is consisted of chlorine, bromine, iodine, thionyl chloride, sulfuryl chloride, hyposubchloric acid, hyposub bromic acid, N-iodic succinic imide, t-butyl hypo bromite or mixed halogen. And the haloformimine compound is consisted of bromochlroroformaldoxime, dibromoformaldoxime, dichlroroformaldoxime, 2-chlroro-2-hydroxyimino acetic acid, 2-bromo-2-hydroxyimino octyl acetate.
