| Abstract: | The process conditions for the synthesis in esterification of antioxidant 168, tris （2,4- diterbutylphenyl） phosphite were studied. The 68.8 g （1/3 mol） of 2,4-ditertbutyl phenol and the 15.4 g （1/9 mol） of phosphorus trichloride were as raw materials with the triethylamine catalyst. The conditions for esterification reaction were that the reaction temperature 140-150℃, reaction time 2.5 h firstly, then crystallization of the reaction product with isopropyl alcohol, getting tris （2,4-ditertbutylphenyl）phosphite. The average yield for the antioxidant 168 is above 95%. |
