Abstract:
The present invention relates to a continuous process for preparing neral (cis-citral) in pure or enriched form by distillatively separating neral from substance mixtures comprising essentially neral and geranial (trans-citral). This distillative separation is performed in a dividing wall column or in a connection of two distillation columns in the form of a thermal coupling.
