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.

[0032] Preferably, the ethanol added in step (3) is absolute ethanol.

Abstract

The invention relates to ascorbic acid lithium and a preparation method thereof. The preparation method of ascorbic acid lithium comprises the following steps: (1) feeding lithium carbonate and ascorbic acid to a water solution to carry out chemical reaction, so as to generate ascorbic acid lithium; (2) continuing to add ethanol to a reaction solution, and separating out ascorbic acid lithium crystal. The prepared ascorbic acid lithium is soluble in water and is organic lithium, can be applied to the field of medicines or foods, for example, can be used as antioxidant preservatives in foods, condiments or beverage, and can also be used as a good drug for treating mania, bipolar affective disorders of alternating attacks of mania and depression, dissociation-affective disorder, cold bronchitis, asthma, pneumonia, hepatitis, liver cancer and high blood pressure.

Description

technical field [0001] The invention relates to the field of biochemical industry, medicine and food, in particular to a new substance lithium ascorbate and a preparation method thereof. Background technique [0002] In today's biochemical, pharmaceutical and food markets at home and abroad, lithium carbonate is mainly used for the treatment of mania, bipolar affective disorder and schizoaffective psychosis with alternating episodes of mania and depression. Its English name: Lithium carbonate, chemical formula: Li 2 CO 3 , molecular weight: 73.89. However, lithium carbonate is inorganic lithium, which is slightly soluble in water and has 1.33g of Li at 20°C 2 CO 3 The dissolved amount per 100ml is not conducive to human absorption, so its efficacy is limited. [0003] At present, although ascorbic acid has the effect of preventing cancer, heart disease, stroke, and protecting teeth and gums, it cannot treat other diseases such as mania, bipolar disorder with alternating ...
