怎么由L-脯氨酸合成L-脯氨酸钠？ 直接加碳酸氢钠吗？会不会将L-脯氨酸消旋了？ |

A solution containing 0.3 kg of sodium hydroxide dissolved in 1.0 liter of deionized water [(DIW)] was prepared and injected into a 27 liter reaction vessel. The sodium hydroxide solution in the reaction vessel was cooled to room temperature with an ice/salt bath, and then 0.5 kg of L-prolin was added to the alkaline solution and dissolved with stirring, making a solution having a 1: 2 ratio of L-proline to [NAOH.] Cooling of the solution was continued to a temperature [OF-10.deg.C] to [10.deg.C.] The reaction medium was then diluted with about 2 liters of ethanol. The reaction vessel was purged with nitrogen gas and kept under a constant nitrogen atmosphere during the remainder of the synthesis process. 英语应该能解决吧 Publ.: WO2003/99784 A1 (2003/12/04), Appl.: WO2003-US14890 (2003/05/08)你可以把专利调出来 也是一样，你看看吧，相信对你有帮助 祝你成功 |
