Disclosed is a process for the preparation of an aminoaryl thiophosphate or phosphate which comprises hydrolyzing an N-acetylaminoaryl thiophosphate or phosphate by heating it in an aqueous solution of a mineral acid. The N-acetylaminoaryl thiophosphate or phosphate can be obtained by condensing an anhydrous alkali metal salt of an N-acetylaminophenol with phosphorus thiochloride or phosphorus oxychloride at a high temperature in the presence of an inert organic solvent or by condensing an N-acetylaminophenol with phosphorus thiochloride or phosphorus oxychloride in the presence of an alkali metal hydroxide or carbonate, water, and an organic solvent.
