| Abstract: | Octanol phosphoric ester was prepared with octanol and phosphorus pentoxide. Main factors affecting the reaction were discussed and optimum technological conditions were given. Molar ratio of octanol to phosphorus pentoxide was (2.5-3.5): 1.0, esterification time was about 3-4 h, and reaction temperature was controlled at 60- 70 ℃.Properties and application of sodium octyl phosphate in penetrating agents were introduced. |
