The method of the synthesis of dibutyl phosphate from phosphorous acid and n-butanol has been explored. Effects of reaction conditions, such as the ratio of raw materials, reaction temperature, reaction time, catalyst type, and reaction time were investigated. The methods of analysis were studied. The composition of product was analyzed by titration method. The result showed: the best temperature was 125-135 degrees C, the mole ratio of n-butanol / phosphorous acid was 3.6, the best reaction time without catalyst was 3h, the yield of dibutyl phosphate was 68%. The product can be separated by the agent of n-butanol/benzene 10:1 in TLC.
