Abstract
Abstract A process for preparing an acetal or a ketal comprises contacting an olefin with an alcohol at elevated temperature in the presence of a dihydrocarbyl peroxide and a catalyst comprising palladium and a copper compound. The process is preferably carried out in the presence of an amine which is unable to coordinate to the catalyst.
