CAS No.:64-18-6

HS Code:291511004

UN No.:N/A

EC NO: 200-579-1

Molecular Structure:

Molecular Formula: CH2O2

Molecular Weight:46.03MP: 8.4°C

BP: 101°C

Density: 1.22g/ml

Acidity(pKa):3.744MSDS: Available on request

Property:    Colorless transparent oily liquid smoke,with the irritating odor.Formic acid is miscible with water and most polar organic solvents, and somewhat soluble in hydrocarbons. In hydrocarbons and in the vapor phase it consists of hydrogen-bonded dimers rather than individual molecules. Owing to its tendency to hydrogen-bond, gaseous formic acid does not obey the ideal gas law. Solid formic acid (two polymorphs) consists of an effectively endless network of hydrogen-bonded formic acid molecules. This relatively complicated compound also forms a low-boiling azeotrope with water (22.4%) and liquid formic acid also tends to supercool.
