Title:
PROCESS FOR THE PURIFICATION AND RECOVERY OF ACETONITRILE
Document Type and Number:
WIPO Patent Application WO2002006212
Kind Code:
A3
Abstract:
A method for the purification of crude acetonitrile comprising distilling the crude acetonitrile in a first fractional distillation column at below atmospheric pressure, withdrawing a first side draw fraction comprising acetonitrile, distilling the first side draw fraction in a second fractional distillation column at super atmospheric pressure, and withdrawing from the second distillation a second side draw fraction comprising purified acetonitrile.
