Definition: Semicarbonization is a chemical process in which carbon dioxide (CO2) and water are combined to form carbon tetrachloride (CCl4). This reaction takes place at high temperatures, typically around 1500°C. The resulting compound has the formula CCl4. The term "semicarbonize" refers to the conversion of one molecule into multiple molecules of a different type based on the process of carbon dioxide being used as reactant and water being consumed as
