Asetik asitin hazırlanması için mikrobik işlem ve asetik asetin sıvı fermentasyon kültür ortamından ekstre edilmesi için çözücü

摘要

A modified Solvent immiscible with water, useful in the extraction of acetic acid from aqueous streams.It is a mixture of isomers of substantially Pure di - and branched alkyl amines this Solvent is substantially free of mono - alkyl amines and alcohols.Solvent mixtures formed of this Solvent modified with a desired cosolvent, preferably Low Point of Hydrocarbon ebullicionque forms an azeotrope with water.They are useful in the extraction of acetic acid from aqueous gaseous streams.A procedure of anaerobic microbial fermentation for the production of acetic acid from aqueous gaseous streams.A procedure of anaerobic microbial fermentation for the production of acetic acid used in these Solvents, under conditions that limit the formation of amides by SolventAnd thus increases the performance of the Recovery of acetic acid.Methods for the direct extraction of acetic acid and the Extractive fermentation of acetic acid also employ the modified Solvent and increase the performance of acid productionAcetic acid.These increases in performance also obtains when the source of Energy for the microbial fermentation contains Carbon Dioxide,The Method includes a step of retroextraccion carbon dioxide before the extraction of acetic acid in the solvent.
