Abstract : The alkyl phosphate is prepared by using polyphosphoric acid and hexadecanol as raw materials. The experimental result shows that the yield of alkyl monophosphate reaches 93. 4 % and total yield of alkyl phosphate is 94. 5 %, when a percentage of phosphorous pentoxide in the phosphoric acid is 79. 98 % and mole ratio of hexadecanol to phosphoric acid is 0. 90 at 75 ℃for 6 hours.
Keywords: polyphosphoric acid, hexadecanol, alkyl phosphate, alkyl monophosphate
