Formic Acid

Formic acid is a low flammable, biodegradable, and stable liquid under ambient conditions, with a boiling point of 101°C and a freezing point of 8.3°C. It is a colorless, clear, and corrosive liquid with a pungent odor. it is an efficient organic acid that is environmentally friendly and used in many different applications. 


1- it is an organic acid  used in oil- and gas-well stimulation treatments. 

2- it has an advantage over HCl in that formic acid is easier to inhibit against pipe corrosion at temperatures as high as 400°F . 

3- it is intermediate in strength between hydrochloric acid  and acetic acid. 

4- It corrodes steel more uniformly than does HCl and causes less pitting.
