| titleOfInvention | Method of extracting, distilling and separating 3-hydroxyl butanone from fermentation liquor by adding salts |
| abstract | The invention belongs to the technical field of bioengineering and particularly discloses a method of extracting, distilling and separating 3-hydroxyl butanone from fermentation liquor by adding salts. The method of extracting, distilling and separating 3-hydroxyl butanone from fermentation liquor by adding salts comprises the following steps: adding soluble inorganic salts in fermentation clear liquor of 3-hydroxyl butanone; adding a hydrophobic organic solvent after the soluble inorganic salt is solved, shocking intermittently after mixing; collecting an inorganic salt lower phase after extracting; re-adding the organic solvent into the inorganic salt lower phase to carry out secondary extraction, and operating repeatedly; adding an appropriate amount of anhydrous sodium sulfate after merging a collected organic solvent upper phase, drying the organic solvent until no water exists; and recycling the organic solvent by normal-pressure distillation to obtain a yellow sticky 3-hydroxyl butanone sample. The method disclosed by the invention is simple to operate, low in energy consumption, suitable for industrial production and application; the organic solvent and the inorganic salts in an operation process can be recycled, so that not only can cost be saved and resource utilization efficiency be improved, but also modern green environment-friendly needs can be satisfied. |
