Description

Soluble in water, slightly soluble in ethanol, insoluble in ether and most other organic solvents. In aqueous solution, partial conversion to gamma and delta lactone, and a balanced mixture. Acidity of aqueous solution. Aqueous solution with concentration of 4% pH=1.8. Because it is difficult to make solid, the commodity is usually 50% aqueous solution, a light amber, with light vinegar taste, relative density of 1.2425. Acting as sodium salt or calcium salt with alkali, reducing the sugar into Arabia sugar under the action of peroxide, and being oxidized to formaldehyde, oxalic acid and glyoxylic acid under the action of HIO4. Preferably stored in stainless steel tanks.
