摘要：

Bronsted acid catalyzed condensations of meso-erythritol with aldehyde/ketones were studied using mesoerythritol:aldehyde/ketone 1:3 ratio in a Dean-Stark apparatus. The selectivity among bis-ketal and 1,3-dioxolane-ether formation can be achieved by choosing between homogeneous and heterogeneous catalysts. The catalysts could be reused without appreciable loss in activity.
