The present invention relates to a method for purifying β-hydroxyl-β-methyl butyrate, comprising neutralizing a crude β-hydroxyl-β-methyl butyrate with a base to produce a salt of β-hydroxyl-β-methyl butyrate, cooling and crystallizing, dissolving and acidifying, and extracting to obtain β-hydroxyl-β-methyl butyrate of high purity. No strict conditions, such as high temperature and high vacuum, are required in this method. On the contrary, it has low requirement on the apparatus, the process can readily be controlled and a product with high purity can be produced.
本发明涉及一种用于纯化β-羟基-β-
甲基丁酸盐的方法,包括用碱中和粗β-羟基-β-
甲基丁酸盐以产生β-羟基-β-
甲基丁酸盐,冷却结晶,溶解酸化,提取以获得高纯度的β-羟基-β-
甲基丁酸盐。该方法不需要严格的条件,如高温和高真空。相反,它对设备的要求低,过程可以轻松控制,并且可以生产高纯度的产品。
