摘要：

The purified Tunisian clay G and the commercialized American clay W were pillared with zirconium, aluminum and mixed pillars zirconium-aluminum, cerium-zirconium, cerium-aluminum, and cerium-zirconium-aluminum. These different clays were used in the synthesis of 2,2-dimethyl-1,3-dioxolane 3 by acetalyzation of acetone 2 with ethylene glycol 1 under autogenously pressure and without solvent. Results indicate that the yield of product 3 depends of the nature and the acidity of the clay used and the time of reaction. (C) 2012 Academic des sciences. Published by Elsevier Masson SAS.
