The present invention relates to a process for preparing acetals of &agr;,&bgr;-dicarbonyl compounds of the general formula
(R″O)
2
CRCR′(OR″)
2
which are obtained by continuous reaction of &agr;,&bgr;-dicarbonyl compounds R—CO—CO—R′ with alcohols R″OH or HO—X—OH in countercurrent.
本发明涉及一种制备一般式为(R″O)2CRCR′(OR″)2的α,β-二羰基化合物
缩醛的方法,该方法通过将α,β-二羰基化合物R—CO—CO—R′与醇R″OH或HO—X—OH在逆流条件下进行连续反应而获得。
