PROCESS FOR THE CONTINUOUS SEPARATION OF ACETIC ACID FROM AQUEOUS SOLUTIONS OF LOW CONCENTRATIONS

摘要

Acetic acid is recovered from its dilute aqueous solutions by extracting same with an organic solvent, neutralizing the acidic extract with aqueous ammonia, whereby there are separated an organic phase and an ammonium acetate containing aqueous phase, and thence thermally decomposing said ammonium acetate.
