Recovery column for the purification of acrylonitrile/acetonitrile mixtures |
| abstract |
A process for separating acrylonitrile from a mixture of acrylonitrile and acetonitrile includes providing a mixture of acrylonitrile and acetonitrile to a recovery column; contacting the mixture of acrylonitrile and acetonitrile with aqueous solvent to provide an acrylonitrile-water azeotrope; and separating the acrylonitrile-water azeotrope from the acetonitrile to provide an overhead stream that includes the acrylonitrile-water azeotrope and about 0.05 weight percent or less acetonitrile, a bottoms stream that includes about 0 to about 0.0075 weight percent acetonitrile, and a sidestream that includes about 5 to about 70 weight % acetonitrile. |
