Phosphoric esters (mono-, di- or triester) is useful as, for example, a cleaner, an emulsifier, an antistatic agent, metal-chelating agent and a lubricant for fibers. It is produced at a high yield while completely trapping the hydrogen chloride gas formed as a by-product. The reaction between a phosphorus oxyhalide and an organic hydroxyl compound to produce a phosphoric ester is effected in the presence of a metal salt of an acid having a pKa of from -5 to 13.
