Abstract
Aqueous ammoniate solutions made during the manufacture of N-hydrocarbyl thiophosphoric triamides, consisting essentially of aqueous solutions of ammonium chloride and ammonia containing a water-soluble impurity normally tending to engender corrosion of ferrous metal are rendered corrosion-resistant by dissolving therein a small corrosion-inhibiting amount (e.g., up to about 5000 ppm (wt/wt) of a water-soluble salt or oxide of zinc, aluminum, arsenic, antimony or bismuth.
