CA 2351124

Acetals and ketals can be prepared by reacting an aldehyde or ketone with an alcohol in the presence of an acidic catalyst. However, the reaction is reversible and, at ambient temperature or above, the equilibrium of the reaction is shifted to the side of the starting materials, acetal or ketone, and alcohol. Thus, there is described a process for the preparation of acetal or ketal which comprises reacting an aldehyde or ketone with an alcohol in the presence of a solid acid and removing water from the reaction product by pervaporation.
