Formic Acid
CAS Number: 64-18-6
Molecular Formula: CH2O2
Molecular Weight: 46.03
Formic Acid
Formic Acid FCC Food Grade:
HCOOH
CH2O2 Formula weight 46.03
INS: 236 CAS 64-18-6
FEMA: 2487
DESCRIPTION
Formic Acid occurs as a clear, colorless, highly corrosive liquid with a characteristic, pungent odor. It is miscible with water, with alcohol, with glycerin, and with ether. Its specific gravity is about 1.20.
Function: Flavoring adjunct; preservative.
REQUIREMENTS
Identification:
A. Add 2 mL of mercuric chloride to 5 mL of sample, and warm the mixture. A white precipitate of mercurous chloride forms.
B. Neutralize 1 mL of sample with sodium hydroxide, and then add 2 drops in excess and 1 mL of ferric chloride. A deep, red-orange color appears that turns to yellow-orange on the addition of mineral acids.
C. Place 2 mL of sample in a test tube, add 5 mL of sulfuric acid, and test the gas evolved with a lighted splinter. A blue flame characteristic of carbon monoxide is produced.
Assay: Not less than 85.0% of CH2O2.
Acetic Acid: Not more than 0.4%.
Dilution Test: Passes test.
Sulfate: Not more than 0.004%.
