Abstract The acetalization of aldehydes has been studied with ethyleneglycol, 3??chloro??1, 2?? propanediol, 1, 2??propanediol, and 1, 2, 3??propanetriol using resin??D72 catalyst in high yields under reflux and water separator conditions. The reaction is simple, efficient, and chemoselective and does not involve any other additive.
