Description

Technical Field

[0001] The utility model belongs to the technical field of storage tanks, and relates to a methanol storage tank for biopharmaceuticals. Background Art

[0002] Methanol is the simplest saturated monohydric alcohol in structure. It is a colorless liquid with an alcohol smell and is volatile. The lowest oral poisoning dose for humans is about 100 mg / kg body weight, and ingestion of 0.3 - 1 g can be lethal. It is used to manufacture formaldehyde and pesticides, etc., and is used as an extractant for organic substances and a denaturant for alcohol, etc. The finished product is usually prepared by the reaction of carbon monoxide and hydrogen;

[0003] Methanol is toxic, has a low boiling point and is volatile, and there are many problems in storage. In the process of biopharmaceuticals, it is often necessary to dissolve drugs in solvents for subsequent preparation and processing. Since methanol is cheap, easy to obtain, has good stability and strong solubility, it is widely used by pharmaceutical factories. In addition to being used as a drug solvent, methanol can also be used in other pharmaceutical processes, such as for crystallization and separation of drugs. However, during use, the storage tank containing methanol is placed inside the warehouse. Since methanol is volatile, flammable and explosive, if the storage equipment is not tightly sealed, resulting in methanol volatilizing into the air, it will pose risks of poisoning, combustion and explosion. Therefore, we propose a methanol storage tank for biopharmaceuticals. Summary of the Utility Model
