반응 단계

50 g (0.12 mol) of sodium nonylphenyl 2-hydroxy-3-chloropropyl phosphate was charged into a reactor, to which 1000 ml of ethanol was added, followed by agitation and heating to 80° C. to obtain a uniform mixture. Thereafter, the reaction system was cooled down to 30° C., to which was gradually added 53.0 g (0.12 mol) of a 0.0022 mol/g sodium hydroxide ethanol solution, followed by agitation for 4 hours while keeping the temperature. The HPLC analysis revealed the disappearance of a peak of the starting material with a peak for the resultant new product appearing. The resultant NaCl precipitate was removed by filtration and the ethanol was distilled off under reduced pressure to obtain 45 g (yield: 98%) of sodium nonylphenyl glycidyl phosphate.
