production method | is obtained by ring-opening of γ-butyneic acid. Sodium hydroxide was dissolved in water under stirring, and γ-butyrolactone was added dropwise at 50-60 ℃. After the addition, the mixture was kept for 2H, and then decolorized with activated carbon for 40min, the mixture was stirred with ethanol to form a slurry, filtered, washed with a small amount of ethanol, and dried below 80 ° C. To obtain sodium γ-hydroxybutyrate. The yield was 90%. |
