ABSTRACT:
A process for the preparation of 4-acetals of butene-1,4-dial of the formula ##STR1## where R is an alkyl, alkenyl, cycloalkyl or aralkyl radical of 1 to 12 carbon atoms which may contain alkoxy groups, or the two radicals R together form an alkylene or alkenylene radical of 2 to 10 carbon atoms which may contain alkoxy groups, and R.sup.1 is an alkyl, alkenyl or alkynyl radical of 1 to 12 carbon atoms which may be substituted by cycloaliphatic, aromatic or heterocyclic radicals or by hydroxyl, ether, thioether, acyl, alkylamino, carboxyl or carbalkoxy groups, or is an unsubstituted or substituted aryl radical or an alkoxy, alkylthio or acyloxy group, wherein a glyoxal monoacetal of the formula ##STR2## is reacted with an aldehyde of the formula
