| titleOfInvention | A kind of preparation method of high optical selectivity D-pantolactone |
| abstract | The invention discloses a method for preparing D-pantolactone with high optical selectivity. The specific steps are as follows: adding an enzyme preparation to a substrate solution, and splitting to obtain D-pantolactone; wherein, the Described substrate solution is DL-pantolactone and carbonate, and described enzyme preparation is D-pantolactone hydrolase; Described carbonate is any in potassium carbonate, sodium carbonate, ammonium carbonate kind; the pH value of the substrate solution is 5-8, the concentration of DL-pantolactone in the substrate solution is 10-400g/L, and the concentration of potassium carbonate in the substrate solution is 1- 80g/L. The pH value of the system is regulated by carbonate, and D-pantolactone hydrolase is used as a catalyst to catalyze the hydrolysis of D-pantolactone in DL-pantolactone to generate D-pantoic acid. The hydrolysis reaction time is short, the selectivity is high, the degree of the hydrolysis reaction is high, and the subsequent processing steps are simple, so that D-pantolactone with high optical purity can be obtained. |
