| titleOfInvention | A method of extracting pyruvic acid from microbial fermentation solution or enzymatic conversion liquid |
| abstract | The method that the invention discloses a kind of to extract pyruvic acid from microbial fermentation solution or enzymatic conversion liquid, belongs to bio-separation extractive technique field.The present invention, with the extraction of the water-insoluble organic solvents such as ethyl acetate or butyl acetate, the vacuum distillation water-insoluble organic solvents such as extractant ethyl acetate and/or butyl acetate and water therein, continues to obtain qualified acetone acid product using high vacuum vacuum distillation or molecular distillation after centrifugation goes thallus solid visible with other, ultrafiltration removal big molecular impurity, concentration is evaporated under reduced pressure.The present invention has many advantages, such as that technological operation is simple and efficient, expense is low, product purity is high, is suitable for the industrialized production of pyruvic acid. |
