Small amounts of paraformaldehyde and a carboxylic acid are added to a reaction mixture of trialkylbenzene and 3,5-dialkyl-4-hydroxybenzyl alcohol to thereby increase the yield of the product: trialkyl-tris(3,5-dialkyl-4--hydroxybenzyl)benzene. The reaction catalyst, sulfuric acid or a Friedel-Crafts catalyst, is not adversely affected by the additional ingredients.
