| Abstract: | Several purifying techniques of 1,3-propanediol are reviewed which will be used industrially in dilute fermentation broth, including the evaporation and distillation, the solvent extraction, the cationic resin adsorption , the molecular sieve adsorption and the reactive extraction technique. They are discussed in detail and compared with each other in the purifying process and the separation result. It is put forward that the reactive extraction method is conformable in purifying 1,3-propanediol from dilute fermentation broth. |
