| titleOfInvention | Process for smelting bio-based propylene glycol |
| abstract | A method for smelting bio-based propylene glycol is provided, wherein impurities having a boiling point close to that of propylene glycol are separated. In the method of the present invention, a C 5 -C 20 lipophilic alcohol compound, a C 5 -C 20 alkane and/or a C 4 -C 20 lipophilic ketone compound is used as an azeotropic agent using bio-based propylene glycol. performing an azeotropic method to obtain an azeotropic mixture containing propylene glycol; Then, the azeotrope in the azeotrope is separated and removed to obtain crude propylene glycol; The crude propylene glycol is further purified to obtain propylene glycol. |
