3,5-di-alkyl-4-hydroxybenzyl-substituted aromatics are made in improved yield by co-feeding 2,6-di-alkyl-4-alkoxymethyl phenol and sulfuric acid to a benzene compound, e.g., mesitylene, in an inert solvent at -10 to 50°C.
在 -10 至 50°C 的惰性溶剂中,将 2,6-二烷基-4-烷氧基甲基苯酚和硫酸同时加入苯化合物(如甲苯)中,可提高 3,5-二烷基-4-羟基苄基取代的芳烃的产率。
