    • A method for making a hindered phenolic antioxidant based on Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate uses a methanol solution containing alkali metal methoxide as a catalyst solution, wherein the catalyst solution is filtered with a filter device with a filter pore diameter of less than 50 μm to remove insoluble matters therefrom before used in a transesterification process where methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate and 1-Octadecanol are taken as reactants to obtain a crude product of Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate having high conversion rate and low color, and the crude product further undergoes a purification process for crystallization, filtering and drying to obtain a product of Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate having high purity and low color.
