| Abstract: | Triethylene glycol bis3-(3,5-di-tert-butyl-4-hydroxyphenyl)]propionate was synthesized by transesterification of methyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate with triethylene glycol without solvent.The optimum conditions were found as follows:2.3%organic tin based on MPC as catalyst,adding at 90℃,reaction temperature 130℃,reaction time 3.5 h,and molar ratio of MPC to triethylene glycol 2.10:1.00.Under these conditions,the yield of the product could reach 91%. The melting point of the product was 106-106.5℃.The product was characterized by elemental analysis, IR and ~1H NMR. |
| Keywords: | triethylene glycol bis[3-(3 5-di-tert-butyl-4-hydroxyphenyl)]propionate methyl-3-(3 5-di-tert-butyl-4-hydroxyphenyl)propionate triethylene glycol ester exchange reaction |
