Neutralization of ammonia gas instead of ammonia water, with acetic acid, the ammonium acetate can be obtained through centrifugation. Then, introduce efficient solubilizer into the chloroform and the mother liquor; remove the chloroform layer and the impurities through counter extraction, 98 % rich fraction of acephate is ultimately obtained.
