Problems solved by technology

[0002] Thiazole, molecular formula: C3H3NS, appearance and properties are colorless or light yellow, with a special odor, liquid, can be used as organic synthesis reagents, used in the synthesis of drugs, dyes, rubber accelerators, film color, fungicides and dyes, etc.; Thiazoles are toxic to a certain extent, harmful to the body after inhalation, ingestion or absorption through the skin, and irritating to the eyes and skin. At the same time, thiazoles are also flammable substances, which may cause combustion and explosion when exposed to open flames, high heat or contact with oxidants Therefore, it must be safe during storage, but at present there is no relatively scientific and systematic storage method. Therefore, researching a safe, simple and systematic storage method for thiazole is an urgently needed technology at present.

Embodiment 1

[0017] A conventional storage method for thiazole, comprising the following steps:

[0018] ①. Collect or newly prepare thiazole. The collected thiazole should not exceed 5 hours, and the thiazole must be pure and free of other impurities;

[0019] ②. Preliminarily clean up the thiazoles collected above, place them in multiple containers, and then place the containers in the cold storage, and adjust the temperature in the storage to 5°C;

[0020] ③. Adjust the humidity in the above-mentioned cold storage to 30%, and then adjust the carbon dioxide content to 35%;

[0021] ④. Fill the container filled with thiazole with water, the water should be 5cm higher than the thiazole liquid level, then shake it slightly and let it stand;

[0022] ⑤. Take a sealed tank, the sealed tank is a glass tank and the glass is brown glass, and a layer of quicklime is laid on the bottom of the sealed tank, and then a layer of soft cloth is laid on the quicklime, and then the above-mentioned contai...

Embodiment 2

[0026] A conventional storage method for thiazole is characterized in that it comprises the following steps:

[0027] ①. Collect or newly prepare thiazole. The collected thiazole should not exceed 5 hours, and the thiazole must be pure and free of other impurities;

[0028] ②. Preliminarily clean up the thiazoles collected above, place them in multiple containers, and then place the containers in the cold storage, and adjust the temperature in the storage to 2°C;

[0029] ③. Adjust the humidity in the above-mentioned cold storage to 20%, and then adjust the carbon dioxide content to 24%;

[0030] ④. Fill the container filled with thiazole with water, the water should be 3cm higher than the thiazole liquid level, then shake it slightly and let it stand;

[0031] ⑤. Take a sealed tank, the sealed tank is a glass tank and the glass is brown glass, and a layer of quicklime is laid on the bottom of the sealed tank, and then a layer of soft cloth is laid on the quick lime, and then...

Abstract

The invention discloses a conventional storage method for thiazole, and relates to the technical field of medicine intermediate processing. The method comprises the steps of collecting the thiazole, pretreating the thiazole, carrying out water sealing on the thiazole, grouping and bottling the thiazole, and then hermitically storing bottles with the thiazole. The storage method for the thiazole has the beneficial effects that suitable conditions favorable for storage of the thiazole are determined, reasonable temperature and humidity in a storehouse during thiazole storage are guaranteed, the problems of volatilization and modification of the thiazole in the storage process are solved, the thiazole storage time is prolonged, the actual performance of the thiazole cannot be lowered, and long-time storage is facilitated.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical intermediate processing, in particular to a safe storage method for thiazole. Background technique [0002] Thiazole, molecular formula: C3H3NS, appearance and properties are colorless or light yellow, with a special odor, liquid, can be used as organic synthesis reagents, used in the synthesis of drugs, dyes, rubber accelerators, film color, fungicides and dyes, etc.; Thiazoles are toxic to a certain extent, harmful to the body after inhalation, ingestion or absorption through the skin, and irritating to the eyes and skin. At the same time, thiazoles are also flammable substances, which may cause combustion and explosion when exposed to open flames, high heat or contact with oxidants Therefore, it must be safe during storage, but at present there is no relatively scientific and systematic storage method. Therefore, research on a safe, simple and systematic storage method for thiazole is an...
