---|---|---|
12.8 g | With sodium hydroxide; In methanol; at 50 - 60℃; for 1h; | In a 500 ml three-necked flask, 100 ml of methanol,9.71 g of zinc acetate dihydrate, 10 g of L-<strong>[305-84-0]carnosine</strong> was added and suspended,And gradually heated to maintain the temperature at 60 C. 3.52 g of sodium hydroxide was completely dissolved in 70 ml of methanol,Sodium hydroxide solution was prepared,Was slowly added to the suspension.The reaction solution was stirred at 50 to 60 DEG CAfter stirring for 1 hour,Cooled to 30 & lt; 0 & gt; C, and 80 ml of purified water was gradually added dropwise for 30 minutes. After the addition of purified water, the mixture was stirred at the same temperature for 1 hour,Filtered under reduced pressure, washed sequentially with 80 ml of purified water and 80 ml of methanol,12.8 g of a white powdery crystal was obtained.NMR analysis of the white powdery crystal revealed that the content of sodium acetate was 0.5% by weight. |
