Embodiment 1
[0022] The preparation method of lithium ascorbate of the present embodiment comprises the following steps:
[0023] (1) Weigh 73.89g of lithium carbonate and 352.26g of ascorbic acid, put the obtained lithium carbonate and ascorbic acid into the aqueous solution for reaction, and react to generate lithium ascorbate. The chemical reaction formula is: Li 2 CO 3 +2C 6 h 8 o 6 =2LiC 6 h 7 o 6 +H 2 O+CO 2 ↑, the reaction condition is normal temperature;
[0024] (2) Continue adding ethanol to the reaction solution; precipitate lithium ascorbate crystals, and filter and wash the materials after the reaction to obtain lithium ascorbate crystals;
[0025] (3) Dry the lithium ascorbate crystals to obtain 364.14 g of lithium ascorbate, and then pack the finished product.
[0026] Preferably, the ethanol added in step (2) is absolute ethanol.
Embodiment 2
[0028] The preparation method of lithium ascorbate in the present embodiment comprises the following steps:
[0029] (1) Weigh 147.78g of lithium carbonate and 704.52g of ascorbic acid, put the obtained lithium carbonate and ascorbic acid into the aqueous solution for reaction, and react to generate lithium ascorbate. The chemical reaction formula is: Li 2 CO 3 +2C 6 h 8 o 6 =2LiC 6 h 7 o 6 +H 2 O+CO 2 ↑, the reaction condition is normal temperature;
[0030] (2) Continue to add ethanol to the reaction solution to precipitate lithium ascorbate crystals, and filter and wash the materials after the reaction to obtain lithium ascorbate crystals;
[0031] (3) Dry the lithium ascorbate crystals to obtain 728.28g of lithium ascorbate, and then pack the finished product.
