Reaction Steps

Octadecyl 3-(3,5-di-tertbutyl-4-hydroxyphenyl)-propionate was prepared from 124.8 g (0.427 mole) of methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, 88.8 g (0.328 mole) of octadecyl alcohol and 0.13 g (0.0007 mole) of monobutyltin oxide. To the solution (214 g) of it was added 35 g of synthetic magnesium silicate (manufactured by Mizusawa Chemical Co.), and the solution was stirred at 60° C. for 0.5 hour. The organic layer wa separated by filtration. The residual tin content was 3 ppm (removal rate: 99.2%).
