【Abstract】 The synthetic process of dialkyl phosphate by reaction of longchain alcohol with phosphorus oxychloride was studied. The influence of molar ratio of reactants, reaction temperature, reaction time on process of esterification and hydrolysis was investigated too. By orthogonal experiments, the optimum technological conditions were determined as follows, the molar ratio of alcohol to phosphorus oxychloride 2.0∶1, the time of adding alcohol 2.0 h, esterfying temperature 45 ℃ and the time 6.0 h, hydrolytic temperature 60 ℃ and the time 2.0 h, the adding water 1∶0.5. The content of dialkyl phosphate was more than 95%.更多还原
