一种制备L-2,4-二氨基丁酸的方法
摘要：
本发明公开了一种制备L-2，4-二氨基丁酸的方法，将γ-聚二氨基丁酸经水解、分离、干燥后制备L-2，4-二氨基丁酸；其中，所述的水解方法为加压水解、或有机酸水解、或酸性树脂结合亚硝酸钠水解、或蛋白酶水解。本发明方法工艺简单，操作方便，效率高且无需脱色处理，是国内外首次对L-2，4-二氨基丁酸这一具有巨大应用前景的产品生产工艺的总结。
摘要（英）：

The invention discloses a preparation method for L-2,4-diaminobutyric acid. The method is performed through hydrolyzing gamma-poly(diaminobutyric acid), separating and drying, wherein the hydrolyzing process comprises pressure hydrolysis, or organic acid hydrolysis, or acidic resin combined sodium nitrite hydrolysis, or protease hydrolysis. The preparation method provided by the invention has the advantages of simple process, high efficiency and no need for decoloring treatment, and is convenient to operate, is the first summary of the production process for L-2,4-diaminobutyric acid with excellent application prospect at home and abroad.
