Properties and stability
Avoid contact with strong oxidants.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging is sealed. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be stocked with appropriate
Material to contain spills.
Synthesis method
Use gallic acid and nitric acid Bismuth forms a salt, and bismuth gallate is obtained in one step. Add gallic acid and appropriate amount of water to the stainless steel tank and heat to 90 ℃Dissolve it and filter it to obtain a gallic acid aqueous solution. Take another bismuth nitrate and add a little hot water, stir until there are no bismuth nitrate particles, add the gallic acid aqueous solution while stirring, and continue stirring0.5h, out. After precipitation and filtration, the filter cake is 50℃Wash with water, filter after no sour smell, in70 ℃Following drying, bismuth subgallate is obtained.
Purpose
This product is an astringent. and antiseptics, used externally for skin diseases such as eczema.
