| | DICETYL PHOSPHATE Usage And Synthesis |
| Uses | dicetyl phosphate is used in cosmetic preparations as an emulsifier and surfactant. | | Uses | Dihexadecyl phosphate is a lipid used for research purposes. | | Definition | ChEBI: The dihexadecyl ester of phosphoric acid. | | Biochem/physiol Actions | Dihexadecyl phosphate (DHP) is a negatively charged lipid that is used for the formation of model membranes. | | Synthesis | The general procedure for the synthesis of bishexadecyl phosphate from 1-hexadecanol is as follows:
1. Phosphorus trichloride (2.5 ml, 26.8 mmol) was added slowly and dropwise to a mixture of 1-hexadecanol (19.50 g, 80.4 mmol) and benzene (100 ml) at 80 °C (solvent reflux temperature) and the reaction was continued with stirring for 12 hrs at this temperature.
2. Upon completion of the reaction, the solvent in the reaction solution was removed by distillation under reduced pressure.
3. benzene (50 ml) was added to the residue obtained after decompression distillation and the mixture was cooled overnight to promote crystallization.
4. The cooled mixture was filtered and the resulting white precipitate, i.e., bishexadecyl phosphate (1.64 g, 3.0 mmol, yield: 11%) was collected.
The product characterization data were as follows:
1H-NMR (ppm) δ: 0.87-0.89 (t, 6H), 1.25-1.37 (br, s, 52H), 1.65-1.72 (m, 4H), 4.00-4.06 (m, 4H), 7.05 (br, s, 1H).
13C-NMR (ppm) δ: 14.11, 22.69, 25.44, 29.18, 29.36, 29.54, 29.61, 29.66, 29.67, 29.70, 29.71, 30.16, 30.21, 31.93, 67.69, 67.73.
31P-NMR (ppm) δ: 2.15.
