Procedure

To 14.6 g (0.095 mol) of phosphorus oxychloride in hexane, 51.4 g (0.190 mol) of 2-heptylundecyl alcohol, 19.2 g (0.190 mol) of triethylamine in hexane were added dropwise while maintaining the temperature at not higher than 0° C. After ripening the mixture at 25° C., a hydrochloric acid salt of triethylamine was removed by washing. The solvent was also removed to obtain 59.1 g (0.095 mol) of bis(2-heptylundecyl) phosphoric chloride (not less than 95% purity was confirmed by 31-NMR)
