1、Carbon dioxide (CAS NO.124-38-9) was one of the first gases to be described as a substance distinct from air. In the seventeenth century, the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original charcoal.
2、The properties of Carbon dioxide (CAS NO.124-38-9) were studied more thoroughly in the 1750s by the Scottish physician Joseph Black.
3、Carbon dioxide (CAS NO.124-38-9) was first liquefied (at elevated pressures) in 1823 by Humphry Davy and Michael Faraday.The earliest description of solid carbon dioxide was given by Charles Thilorier, who in 1834 opened a pressurized container of liquid carbon dioxide, only to find that the cooling produced by the rapid evaporation of the liquid yielded a "snow" of solid CO2.
1、Carbon dioxide (CAS NO.124-38-9) is used by the food industry, the oil industry, and the chemical industry. It is used in many consumer products.
2、Carbon dioxide (CAS NO.124-38-9) is used to produce carbonated soft drinks and soda water.
3、Carbon dioxide (CAS NO.124-38-9) is one of the most commonly used compressed gases for pneumatic (pressurized gas) systems in portable pressure tools and combat robots.
4、Carbon dioxide (CAS NO.124-38-9) also finds use as an atmosphere for welding, although in the welding arc, it reacts to oxidize most metals. It is used as a welding gas primarily because it is much less expensive than more inert gases such as argon or helium.
5、Carbon dioxide (CAS NO.124-38-9) is a good solvent for many lipophilic organic compounds, and is used to remove caffeine from coffee.
6、In the chemical industry, Carbon dioxide (CAS NO.124-38-9) is used for the production of urea, carbonates and bicarbonates, and sodium salicylate.
Carbon dioxide (CAS NO.124-38-9) is produced mainly from six processes:
1、From combustion of fossil fuels and wood;
2、As a by-product of hydrogen production plants, where methane is converted to CO2;
3、As a by-product of fermentation of sugar in the brewing of beer, whisky and other alcoholic beverages;
4、From thermal decomposition of limestone, CaCO3, in the manufacture of lime, CaO;
5、As a by-product of sodium phosphate manufacture;
6、Directly from natural carbon dioxide springs, where it is produced by the action of acidified water on limestone or dolomite.
