Date Mar. 28, 1997An organic hydroxyl compound is reacted with polyphosphoric acid under such conditions that the ratio, as defined by formula (1), has a value exceeding 3.2; and phosphorus pentaoxide is added to the reaction product thus obtained in such an amount that the ratio, as defined by formula (1), has a value in the range of from 2.8 to 3.2: (1) If necessary, the obtained reaction product is deodorized by the removal of the organic hydroxyl compound unreacted therefrom. The process does not give any product of high-viscous gel and therefore enables the industrially easy manufacture of a phosphoric monoester having an extremely high purity, a lowered orthophosphoric acid content, and a good odor.

Abstract: PURPOSE: To obtain a phosphoric monoester useful for detergents, textile treating agents, etc., in high purity and yield without converting the reactional product into a gelatinous material by reacting phosphorus pentoxide, etc., with an organic hydroxy compound under specific conditions. CONSTITUTION: The method for producing a phosphoric monoester is to react phosphorus pentoxide and polyphosphoric acid as phosphorylating agents with an organic hydroxy compound such as octanol under conditions so that a value represented by the formula may exceed 3.2, then add the phosphorus pentoxide to the resultant reactional product and carry out the reaction under conditions that the value, represented by the formula and based on the total amount of the polyphosphoric acid and the phosphorus pentoxide may be 2.8-3.2. Furthermore, the concentration of the polyphosphoric acid is preferably 105-120wt.% expressed in terms of orthophosphoric acid and the unreacted organic hydroxy compound is preferably removed from the reactional product containing the phosphoric monoester by the steam distillation to deodorize the reactional product.
