Melamine trisulfonic acid acetalization of carbonyl compounds under solvent-Free conditions

Abstract EN

Melamine trisulfonic acid has been used as an efficient and recyclable catalyst for acetalization of carbonyl compounds with various alcohols.

Aldehydes and ketones are rapidly transformed into acetals, and ketals at room temperature in high yields using catalytic quantities of melamine trisulfonic acid.

The advantage of this method is the use of a catalyst which is inexpensive, green and stable with an easy procedure and short reaction times.
