PROCESS FOR MAKING ACRYLIC ACID FROM DEXTROSE |
摘要 |
A process is described for making acrylic acid from dextrose, which comprises fermenting dextrose; removing solids from the resulting fermentation broth; removing lactic acid from the clarified broth by extraction into an organic solvent; separating out the lactic acid-loaded organic solvent while recycling at least a portion of the remainder back to the fermentation step; reacting the lactic acid with ammonia to provide a dehydration feed comprising ammonium lactate while preferably recycling the organic solvent; carrying out a vapor phase dehydration of the ammonium lactate to produce a crude acrylic acid product; and purifying the crude acrylic acid by distillation followed by melt crystallization, chromatography or both melt crystallization and chromatography. |
