| [Property]:
|
Colorless, odorless liquid. Relative
density:1.101(-37 ),
boiling point: -78.5(sublimation),
melting point:56.6.
It absorbs large quantity of heat when it is vaporized. It will be
frozen into solid carbon dioxide when the pressure is reduced. It
will form carbon dioxide gas when it is gasified. Carbonic acid will
be formed when part of this product is dissolved into water. Stable
chemical property. |
