2,4,6-Tri(3,5-di-tert-butyl-4-hydroxybenzyl) mesitylene was synthesized using 2,6-di-t-butyl-phenol,paraformaldehyde and mesitylene through etherealization and Friedel-Crafts reaction in two steps.Under the optimum conditions: H2SO4(ω=85%),n(H2SO4) ∶ n(mesitylene)=4∶1,n(2,6-di-t-butyl-4-methoxymethylphenol) ∶n(mesitylene)=4∶1,reaction temperature 10 ℃,dropping time 0.5 h,the yield was 89.2%.
