Abstract: The present invention relates to a method for producing 2-substituted 4-hydroxy-4-methyl tetrahydropyranoles by reacting 3-methylbut-3-en-1-ol (isoprenol) with the corresponding aldehydes in the presence of a strongly acidic cation exchanger. The present invention particularly relates to a corresponding method for producing 2-isobutyl-4-hydroxy-4-methyl tetrahydropyrane by reacting isoprenol with isovaleraldehyde.

Abstract: The present invention relates to a continuous process for preparing racemic or optically active menthol in pure or enriched form by distillative removal of menthol from substance mixtures which comprise essentially menthol and diastereomers thereof. This distillative separation is carried out in a dividing wall column having from 50 to 300 theoretical plates and one or more side draw points at an absolute operating pressure of 5 to 500 mbar.
