Cas Number:111-46-6

Formula:C4H10O3

Molar Mass:106.12

EC Number:203-872-2


Physicochemical properties:

Colorless viscous liquid. Odorless. Microstrip sweet.It’s easy to absorb moisture. It is miscible with ethanol, ether, acetone and ethylene glycol, and is almost insoluble in benzene and carbon tetrachloride. The relative density (d2020) is 1.118. The melting point is -6.5 ° C. The boiling point is 244 ~ 245 ° C. The refractive index (n20D) is 1.4475. The flash point (open cup)is 143 ° C. The median lethal dose (rat, oral) is 20.76 g/kg. Irritating.


Usage:

Solvent. Extracting agent. Gas dehydrating agent. Softener. antifreeze. Lubricant. Gas chromatographic fixative (the maximum using temperature is 50 ° C), suitable for aqueous analysis, similar to polyethylene glycol, for the analysis of oxygenates (especially alcohol), aniline, fatty amines, pyridine and quinoline.
