Apparatus and Process for Using a Nitroalkane as an Entrainer for Azeotropic Removal of Water from Aqueous Acid Solution

摘要

Disclosed are a process and an apparatus for concentrating an organic acid by using a nitroalkane as an entrainer for the azeotropic removal of water from an aqueous organic acid solution. The nitroalkane may be the same as a nitroalkane that is the product of a high pressure nitration process that produces nitroalkanes and aqueous organic acid.
