Patent
·
OSTI ID:5470415
This patent describes a method for recovering n-propanol from a mixture of n-propanol and allyl alcohol which comprises distilling a mixture of n-propanol and allyl alcohol in a rectification column in the presence of about one part of extractive agent per part of n-propanol-allyl alocohol mixture, recovering n-propanol as overhead product, obtaining the allyl alcohol and the extractive agent from the stillpot, separating the allyl alchohol from the extractive agent by distillation in another rectification column, wherein the extractive agent comprises at least one member of the group consisting of acetamide, N,N-dimethylacetamide, adiponitrile, dimethylformamide, dimethylsulfoxide and sulfolane.
