3-propanediol |
| Structural
formula: |
CH3CH2C
(CH2OH) 3 |
| Physical
and Chemical properties: |
| It is white crystal under ordinary
temperature, the boiling point is 295°C under ordinary
pressure, Melting point is 58-59°C, Density of relativeity
is 1.1758(20°C). Easy soluble in acetone, soluble
in carbon tetrachloride, chloroform and ether. Insoluble
in fatty hydrocarbon and aromatic hydrocarbon. stronger
hygroscopic. There are three hydroxymethyls on the a position
of TMP molecule, it possesses the following excellent
properties: it can improve solidity, corrosion-resistant,
sealing, and possesses good stability to water-decomposing,
heat-decomposing and oxidation. Three hydroxyls have same
reaction energy and so on. |
