    摘要: The invention relates to a process for the preparation of glyoxal, alkylglyoxals and acetals thereof by reacting .alpha.,.beta.-unsaturated dialkylacetals with the equivalent amount of ozone and subsequently subjecting the ozonization products to catalytic hydrogenation, the peroxide-containing ozonization solution being fed continuously into a suspension of the hydrogenation catalyst, while a peroxide content of not more than 0.1 mole/liter is maintained, and cleaving the ozonization products by reduction, after which the dialkylacetals formed in the hydrogenation are, if desired, cleaved to give glyoxal or alkylglyoxals.
