Method for obtaining optically active epoxide |
| abstract |
The present invention provides a method capable of suppressing a decrease in optical purity due to the exposure to heat during distillation of an optically active epoxide to permit an optically active epoxide of high quality to be simply obtained on an industrial scale. In the method, an optically active epoxide is distilled in the presence of a base to suppress a decrease in optical purity. |
