Process for the separation, by countercurrentwise liquid-liquid extraction, of a glyoxal diacetal from a crude mixture comprising it

The invention relates to a method for separating a diacetal of the glyoxal of a raw mixture comprising said diacetal of the glyoxal and a monoacetal of the glyoxal, by means of counter-current liquid-liquid extraction.

Process for continuously preparing acetals of alpha, beta-dicarbonyl compounds

The present invention relates to a process for preparing acetals of α,β-dicarbonyl compounds of the general formula (R″O)2CRCR′(OR″)2 which are obtained by continuous reaction of α,β-dicarbonyl compounds R—CO—CO—R′ with alcohols R″OH or HO—X—OH in countercurrent.

Preparation of diacetals of glyoxal

A process is described for preparing diacetals of glyoxal by reacting from 40 to 75% by weight aqueous glyoxal with monohydric alcohols in the presence of an acid catalyst, which comprises leaving a liquid mixture which, at the beginning of the reaction, comprises alcohol and glyoxal in a molar ratio of at least 15:1 and also water in a concentration of not more than 8% by weight in contact with the acid catalyst until concentration in the reaction mixture of the diacetal formed reaches at least 70% of the equilibrium concentration without more than 5% by weight of the alcohol used having already been distilled off.
