Abstract
Three kinds of carriers were utilised to prepare the corresponding sulfonated solid acid catalysts for the alkylation of two different thiophenic compounds (3-methylthiophene and 3-butylthiophene) with 1-hexene. Though the activity of the sulfonated solid acid catalysts was somewhat lower than that of liquid sulfuric acid, the solid acid catalysts had significant advantages in their easy separation, good recycling, selectivity and performance on reuse.
