Abstract
Official abstract text for this publication.
The invention relates to a process for rectificative separation of compositions of matter containing diastereomers of 2-isopropyl-5-methylcyclohexanol by using ionic liquids as extractants.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for separating diastereomers, the process comprising: introducing into an extractive rectification column, a composition of matter containing a mixture of at least two diastereomers of 2-isopropyl-5-methylcyclohexanol, and one or more ionic liquids selected to enhance the boiling point difference between at least one diastereomer of the mixture and at least one other diastereomer of the mixture, wherein the one or more ionic liquids are se…
