Glycerol CAS #56-81-5

Pure glycerol appears as colorless, odorless and sweet viscous liquid. Boiling point: 290 ° C, melting point: 17.9 ° C, the relative density: 1.2613. It can be miscible with water infinitely. It can be dissolved in 11 times ethyl acetate, about 500 times ether. It is insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil. Anhydrous glycerol has a strong water absorption property.
Glycerol is weakly acidic, being able to react with alkaline hydroxide. For example, it reaction with copper hydroxide can produce bright blue cupric glycerinate (can be used to identify polyols). Glycerol can react with nitric acid to generate glyceryl trinitrate, also known as nitroglycerin, being a strong explosive.
