Uses and synthesis of Sodium hydrogen difluoride powder

Sodium hydrogen difluoride Raw Materials is white crystalline powder, soluble in water, aqueous solution is acidic, can corrode glass. Sodium hydrogen difluoride powder is used as antiseptic, food preservative, also used for etching glass, tin plate manufacturing, fabric treatment, rust removal.

Sodium hydrogen difluoride CAS 1333-83-1 is used as food preservative, animal specimen and anatomical specimen preservative and antiseptic.

Colorless or white quicksand crystalline powder.Sodium hydrogen difluoride CAS 1333-83-1 has strong acidic odor. Sodium hydrogen difluoride powder is soluble in water, insoluble in alcohol.

Applications / Functions of Sodium hydrogen difluoride powder

1. Sodium hydrogen difluoride CAS 1333-83-1 is used as an antiseptic, flux, etching agent for engraved glass and as a protective agent for taxidermy.
2. Sodium hydrogen difluoride Raw Materials Used as food protectant, preservative and antiseptic for taxidermy and anatomical specimens.Sodium hydrogen difluoride CAS 1333-83-1 is also used for etching glass, tinplate manufacturing, textile treatment, removing rust, insect control for leather and tinplate production, etc. Sodium hydrogen difluoride CAS 1333-83-1 is also used for etching glass, tinplate manufacturing, textile treatment, removing rust, insect control for leather and tinplate production, etc. Sodium hydrogen difluoride powder mixed with potassium hydrogen fluoride can be used as soldering agent for metals. It can also be used to produce anhydrous hydrogen fluoride.
3. It is used as food and anatomical specimen preservative, rust remover, antiseptic, Sodium hydrogen difluoride powder is also used in etching glass, tin plate manufacturing, textile treatment, leather insect repellent, etc.
4. Sodium hydrogen difluoride Raw Materials Used as food protectant, preservative and antiseptic for animal specimens and anatomical specimens. Also used in etching glass, tin plate manufacturing, textile treatment, rust removal, insect control of leather and tinplate production. Sodium hydrofluoride and potassium hydrofluoride mixture can be used as soldering agent for metals. It can also be used to produce anhydrous hydrogen fluoride.

Physicochemical Property of Sodium hydrogen difluoride powder

Colorless or white quicksand crystalline powder.Sodium hydrogen difluoride Raw Materials has a strong acidic odor. Soluble in water, insoluble in alcohol.

production methodprocess of Sodium hydrogen difluoride powder

Neutralization methodIn a plastic reactor, measure and input 40% hydrofluoric acid, and cool with ice or cold water outside the reactor to maintain the reaction temperature below 5℃. Under stirring, slowly add the filtered saturated soda ash solution in a fine stream, and neutralize it until the Congo red paper is just red. Then cooling, vacuum suction filtration, with a very small amount of water to wash the crystals to remove free acid, and then centrifugal separation, drying at 80 ℃, crushed to produce Sodium hydrogen difluoride Raw Materials. 4HF + Na2CO3 → 2NaHF2 + H20 + CO2↑
