Procedure

The C5 aldehyde mixture thus obtained can be converted, for example by aldol condensation and subsequent hydrogenation of the aldol condensate, to a decanol mixture. In the case of C5 aldehyde mixtures in which the proportion of n-valeraldehyde is less than 95%, it is advisable to remove a proportion of the 2-methylbutanal by distillation in order to obtain a high-quality decanol mixture with a content of 2-propylheptanol of more than 90%.
