Preparative Example 1: Synthesis of February Laurel Phosphates
Phosphoryl chloride (2.5 mL, 26.8 mmol) was added slowly and dropwise to a mixture of lauryl alcohol (15.227 g, 81.7 mmol) and benzene (50 mL) at 80 °C (solvent reflux temperature) and stirring was continued for 21 hours. Upon completion of the reaction, the solvent in the reaction solution was removed by distillation under reduced pressure. Hexane (10 mL) was added to the resulting residue and the mixture was cooled overnight. The resulting white precipitate was filtered to give di(dodecyl) phosphate (white powder, 4.12 g, 9.5 mmol, yield: 35%).
