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.
在三烷基苯和 3,5-二烷基-4-羟基苄醇的反应混合物中加入少量多聚甲醛和一种羧酸,从而提高产物:三烷基-三(3,5-二烷基-4-羟基苄基)苯的产率。反应催化剂(硫酸或 Friedel-Crafts 催化剂)不会受到额外成分的不利影响。
