A method for isolating 1,3-propanediol or 1,3-propanediol and 1,2-propanediol from a solution containing 1,3-propanediol, 1,2-propanediol, glycerol and glcuose

摘要

The present invention comprises a 1, 3- propanediol, 1,2-propanediol , glycerol and glucose a step for reducing evaporation and concentrated mixture ; Concentrate the ethyl acetate , methyl ethyl ketone and fractional distribution of phase in the solvent layer and aqueous layer , respectively, the above compound was allowed to stand for re-dissolving solvent selected from the group consisting of and mixtures thereof ; Contact at low pressure and was then chromatographed on a column of silica is filled condition the solvent layer , MeOH: methanol and mixed well , and comprising the step of elution with a mixed solvent of at least one solvent having a polarity of less than methanol , 1,3 - propanediol, 1,2-propanediol , provides a method for separating 1,3-propanediol from a mixture comprising glycerol and glucose
