pure product is light yellow oily liquid. Soluble in acetone, ethanol, methanol, benzene and other organic solvents, solubility in water (20 deg C) 20mg/L. The light resistance was good, and the thermal decomposition was started at 275 °c.
N-methylene -2,6-= ethyl aniline was prepared by the reaction of 2,6-= ethyl aniline and paraformaldehyde, and then reacted with Chloroacetyl Chloride to form N-(2,6-= ethylphenyl)-N-chloromethylchloroacetamide and finally N-butanol to give butachlor.
It is a selective pre-emergence herbicide, which inhibits the synthesis of protein and kills weeds through the absorption of young shoots and young secondary roots. It is mainly used to control annual grass weeds, annual Cyperaceae weeds and some annual Broad-leaved weeds in rice fields, and also used to control weeds in barley, wheat, cotton and peanut crop fields.
