Formic acid min. 85 % technical (CH2O2)
The formic acid (or methanoic acid) is a colorless, corrosive organic liquid with a characteristic, pungent odor. It is miscible with water, ethanol, glycol and the most polar solvents. In hydrocarbons it is soluble only in trace amounts.
The melting point is 8 ° C, the boiling point of 100.7 ° C.
The formic acid has reducing, antiseptic and insecticidal action. It is used as a solvent, for descaling, as an insecticide, as preservatives for adhesive and polyamide. Very common is the use of formic acid against varroa destructor in bee-keeping.
