Problems solved by technology

Its platinum chloride salt is a yellow lamellae with a melting point of 210°C (decomposition). It is mainly used in electroplating corrosion inhibitors and biochemical reagents, as an intermediate calcium pantothenate for the preparation of chloramphenicol cold plum, and can be used in microbiology and biology. Chemical studies show that β-alanine has a wide range of uses, but after its processing and preparation, due to its own specificity, its activity is easy to decrease during storage, resulting in certain changes in the performance of β-alanine, losing its The original activity affects its actual use effect

Embodiment 1

[0017] A conventional storage method for beta-alanine, comprising the following steps:

[0018] ①. Collect or newly configure β-alanine. The collected β-alanine should not exceed 15 hours, and the β-alanine must be pure and free of other impurities;

[0019] ②. Preliminarily freeze the β-alanine collected above to obtain freeze-dried powder, and then place it in the cold storage, adjust the temperature in the cold storage to 4°C, and pre-cool at low temperature for 15 minutes;

[0020] ③. Take out the above-mentioned β-alanine after low-temperature pre-cooling, put it in a container at a temperature between 0°C, and then add glycerin in it, stir and mix evenly, and let it stand for 20 minutes;

[0021] ④. Put the β-alanine mixed with glycerol in the above step 3 into the cold storage again, then lower the temperature to 4°C, and pre-cool at constant temperature for 5 minutes;

[0022] ⑤. Seal the β-alanine pre-cooled in the above step 4, then control the temperature in the co...

Embodiment 2

[0026] A conventional storage method for beta-alanine, comprising the following steps:

[0027] ①. Collect or newly configure β-alanine. The collected β-alanine should not exceed 15 hours, and the β-alanine must be pure and free of other impurities;

[0028] ②. Preliminarily freeze the β-alanine collected above to obtain freeze-dried powder, and then place it in the cold storage, adjust the temperature in the cold storage to 5°C, and pre-cool at low temperature for 20 minutes;

[0029] ③. Take out the above-mentioned β-alanine after low-temperature pre-cooling, put it in a container at a temperature between 10°C, and then add glycerin in it, stir and mix evenly, and let it rest for 30 minutes;

[0030] ④. Put the β-alanine mixed with glycerol in the above step 3 into the cold storage again, then lower the temperature to 5°C, and pre-cool at constant temperature for 7 minutes;

[0031] ⑤. Seal the β-alanine pre-cooled in the above step 4, then control the temperature in the co...

Abstract

The invention discloses a conventional beta-alanine storage method and relates to the technical field of medical intermediate processing. The conventional beta-alanine storage method comprises the steps of collecting beta-alanine, preprocessing, precooling, adding stabilizer and auxiliaries, cooling and refrigerating. The conventional beta-alanine storage method has the beneficial effects of determining appropriate conditions for beta-alanine storage, guaranteeing reasonable temperature and moisture in a warehouse in which beta-alanine is stored, solving the problems of beta-alanine degeneration and activity reducing in a storage process, prolonging beta-alanine storage time, preventing actual performance of beta-alanine from being damaged and bringing convenience to long-time storage.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical intermediate processing, in particular to a conventional storage method for β-alanine. Background technique [0002] β-alanine, white prismatic crystal, slightly sweet. The melting point is 205°C (decomposition), and the relative density is 1.437. Soluble in water, slightly soluble in ethanol, insoluble in ether and acetone. At 25°C, 55.5g can be dissolved in 100ml of water. The pH value of 50% aqueous solution is 6.0-7.3. Its hydrochloride is white flake or leaf crystal with a melting point of 122.5°C. Its platinum chloride salt is a yellow lamellae with a melting point of 210°C (decomposition). It is mainly used in electroplating corrosion inhibitors and biochemical reagents, as an intermediate calcium pantothenate for the preparation of chloramphenicol cold plum, and can be used in microbiology and biology. Chemical studies show that β-alanine has a wide range of uses, but after its...
