Factory Direct Price 40l Co2 Gas Carbon Dioxide - China
price: 50.00 Dollar US$
Description: nonflammable, nontoxic, colorless and tasteless gas Composition: carbon dioxide Package: carbon dioxide cylinder Cylinder color: as required bon dioxide is a kind of carbon and oxygen compound.
Its chemical formula is CO2 - Its chemical formula amount is 44.0095 - It is a colorless, tasteless, colorless, odorless and slightly sour gas under normal temperature and pressure.
It is also a common greenhouse gas or a component of air (accounting for 0.03% - 0.04% of the total volume of the atmosphere).
In terms of physical properties, the boiling point of carbon dioxide is - 78.5 ℃, the melting point is - 56.6 ℃, the density of carbon dioxide is higher than that of air (under standard conditions), and it is soluble in water.
In terms of chemical properties, the chemical properties of carbon dioxide are not active, with high thermal stability (only 1.8% decomposition at 2000 ℃), unable to burn, and generally do not support combustion.
It belongs to acid oxide, with the generality of acid oxide, because it reacts with water to produce carbonic acid, which is the anhydrides of carbonic acid.
Carbon dioxide can generally be made by calcining limestone at high temperature or reacting limestone with dilute hydrochloric acid.
It is mainly used to refrigerate perishable food (solid), as refrigerant (liquid), to make carbonated soft drink (gas) and as solvent (supercritical state) for homogeneous reaction.
As for its toxicity, research shows that low concentration of carbon dioxide is not toxic, and high concentration of carbon dioxide will cause animal poisoning.
