Method for producing an aliphatic dialdehyde monoacetal |
abstract |
The invention relates to a method for producing a pure aliphatic dialdehyde monoacetal by reacting the corresponding aliphatic dialdehyde or a precursor of the corresponding aliphatic dialdehyde with one or more aliphatic monohydric or polyhydric alcohols, during which water is isolated by distillation while obtaining a reaction mixture that is separated by distillation. The invention is characterized in that the separation by distillation is continuously carried out in a partition column during which pure aliphatic dialdehyde monoacetal is obtained as a side-stream of the partition column or the separation by distillation is continuously carried out in two distillation columns during which crude aliphatic dialdehyde monoacetal is obtained as a side-stream in the first distillation column, the crude aliphatic dialdehyde monoacetal is fed to the second distillation column, and pure aliphatic dialdehyde monoacetal is obtained as a side-stream from the second distillation column. |
