Abstract: A process for preparing a phosphoric ester having reduced odor, comprising contacting a phosphoric ester with at least one of an inert gas and steam at 100 DEG to 160 DEG C in a packed tower; a process for preparing a phosphoric ester having reduced odor, comprising repeating a set of processes comprising (A) heating a phosphoric ester, and contacting the heated phosphoric ester with at least one of an inert gas and steam; and (B) cooling the phosphoric ester obtained in the step (A); a process for preparing a phosphoric ester having reduced odor, comprising adding water to a phosphoric ester, and distilling water from the phosphoric ester under reduced pressure; and a process for preparing a phosphoric ester having reduced odor, comprising reacting an organic hydroxy compound with a phosphorylation agent, while introducing an inert gas into the mixture of the organic hydroxy compound and the phosphorylation agent. The phosphoric ester is useful for, for instance, a shampoo, a cleaning agent, a facial cleansing agent, an emulsifier, and the like.

Abstract: PCT No. PCT/JP95/01890 Sec. 371 Date Mar. 20, 1997 Sec. 102(e) Date Mar. 20, 1997 PCT Filed Sep. 20, 1995 PCT Pub. No. WO96/09305 PCT Pub. 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.
