| 摘 要：以壬基酚聚氧乙烯（9）醚（NPEO-9）和P2O5等為原料，合成了壬基酚聚氧乙烯（9）醚磷酸酯。以反應體系的酯化率、磷酸單酯含量、無(wú)機磷酸含量等為指標，對反應條件進(jìn)行優(yōu)化，優(yōu)化的工藝條件：在亞磷酸存在的情況下，n（NPEO-9）∶n（P2O5）=2.4∶1.0，通過(guò)分步升溫（60 ℃反應1 h，70 ℃反應1 h，90 ℃真空脫水反應2 h）的方式進(jìn)行酯化反應。酯化反應結束后，加入1%的水進(jìn)行水解，得到NPEO-9殘留量低于2%，無(wú)機磷酸低于2%的淺色壬基酚聚氧乙烯（9）醚磷酸酯。 |

| Abstract：Nonylphenol polyoxyethylene (9) ether (NPEO-9) and P2O5 were used as raw materials to synthesize nonylphenol polyoxyethylene(9) ether phosphate. Taking the esterification ratio, the content of phosphate monoester and inorganic phosphoric acid as indicators, the reaction conditions were optimized as followings: in the presence of phosphorous acid and the molar ratio of NPEO-9 to P2O5 was 2.4∶1.0, the esterification reaction was heated up step-by-step (60 ℃ for 1 h, 70 ℃ for 1 h, 90 ℃ for 2 h under vacuum). After the esterification was completed, 1% of water was added for hydrolysis to obtain a light-colored nonylphenol polyoxyethylene(9) ether phosphate with the residual NPEO-9 less than 2% and the inorganic phosphoric acid less than 2%. |
