Product Description

Hydrofluoric aci

 

CAS 7664-39-03

 

It is a sulution of hrdrogen fluride in water,It is a precursor to almost all fluorin compounds, including pharmaceuticals such as fluoxetine (Prozac), diverse materials such as PTFE (Teflo), and elementalfluorin itself. It is a colourless solution that is highly corrosive, capable of dissolving many materials, especiallyoxides. Its ability to dissolve glass has been known since the 17th century, even before Carl Wilhelm Scheele prepared it in large quantities in 1771.[2] Because of its high reactivity toward glass and moderate reactivity toward many metals, hydrofluoric aci is usually stored in plastic containers (although PTFE is slightly permeable to it). Hydrogen fluorid gas is an acute poison that may immediately and permanently damage lungs and the corneas of the eyes.Aqueous hydrofluoric aci is a contact-poison with the potential for deep, initially painless burns and ensuing tissue death. By interfering with body calcium metabolism, the concentrated acid may also cause systemic toxicity and eventualcardiac arrest and fatality, after contact with as little as 160 cm2 (25 square inches) of skin.
