Dry ice is a solid form of carbon dioxide, and the history of dry ice is also the history of carbon dioxide.
"Carbon dioxide" is also called "CO2" and is abundant around us. The air also contains "carbon dioxide". This is because after any substance is burned, "carbon dioxide" will remain in the air. Carbon dioxide, "CO2" is contained in water and minerals and changes its shape at the same time. This "carbon dioxide" is also produced during the respiration and fermentation of living organisms. It is believed that the carbon dioxide content on the earth is about 100 trillion tons. Gas company store carbon dioxide by co2 storage tank,liquid co2 storage tank which as called liquid co2 tanks.
About 400 years ago (about 1600) the Belgian chemist HELMONT named this "carbon dioxide" "Gas Syluestres".
Helmont discovered that the gas produced by burning charcoal is the same substance as the gas produced by fermentation, and named it this way. The reason why gas is called "gas" today is because "carbon dioxide" has such a name.
Similarly, in 1733, the French chemist LAVOISIER revealed that "carbon dioxide" consists of a combination of one C (carbon atom) and two O (oxygen atoms) (CO 2).
In 1823, British physicists DAVY and FARADAY reduced carbon dioxide
To liquefy carbon dioxide at room temperature. In addition, in 1834, German chemists
CHIRORIER successfully solidified "carbon dioxide"
In 1895, British chemists ELWORTHY and HENDERSON applied patent for the solidification method for carbon dioxide, and solid carbon dioxide is recommended as a commercial product in frozen areas.
In 1924, SLATE of the United States filed an invention patent application, such as an effective method of producing solid carbonic acid and a method of using it to keep frozen products at low temperatures. After that, the solid carbonic acid manufacturing company "DRYICE CORPORATION" established in 1925 began industrial production and sales of solid carbonic acid in the suburbs of New York, thus realizing the long-distance transportation of ice cream. Cold storage necessities have become common.
This solid "carbon dioxide" is "dry ice".
Dry ice is used as a coolant.
By taking advantage of its ability to sublime into direct gas (carbon dioxide), it can also be used as an antioxidant and bacterial growth inhibitor for food.
Dry ice is the solid form of carbon dioxide. Carbon dioxide is a colorless and odorless gas under normal conditions. It naturally exists in the air. Although the content of carbon dioxide in the air is relatively small (about 0.03% by volume), it is one of the most important gases we recognize.
Dry ice is very volatile, sublimated to non-toxic, tasteless, 1000 times larger than the solid area
The gas is carbon dioxide, so dry ice cannot be stored in a container with good sealing performance and small volume.
It is easy to explode in the device. Keep the dry ice in a well-ventilated place and Let the gas generated by the volatilization of dry ice be released, so that it is safe.
