High purity 99% Acetic acid glacial cas 64-19-7
Acetic acid, commonly known as acetic acid, is one of the most important fatty acids
because it is the main component of vinegar.
It is found naturally in many plants in the form of free radicals or esters.
Molecular formula CH3COOH.
Vinegar has been brewed and used for thousands of years.
There are records about making vinegar in ancient China.
But concentrated acetic acid was developed by Stahl in 1700.
Pure acetic acid is a colorless liquid with a pungent taste.
Melting point is 16.6 ℃, boiling point 117.9 ℃, the relative density of 1. 049 (20/4 ℃).
Soluble in water, ethanol, glycerin, ether and carbon tetrachloride;
Insoluble in carbon disulfide.
Anhydrous acetic acid solidifies into ice at low temperature, commonly known as glacial acetic acid.
