  • Calcium Carbide - an overview ScienceDirect Topics

    Calcium carbide has the nominal formula of CaC 2 and the molecular weight of 64.0992 g/mol. The pure material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its density is 2.22 g/cc and it melts at 2160 °C with a boiling point (under an inert atmosphere) of 2300 °C, where it decomposes.Its main use industrially is in the production of ...

    2020-5-18  Calcium carbide (CaC 2) is a renewable chemical, which can be recycled from calcium that is abundant in the Earth's crust. Furthermore, CaC 2 rapidly reacts with water. In this work, we used CaC 2 as a dehydrating agent for the direct synthesis of

  • Commercialization of Calcium Carbide and Acetylene ...

    2021-8-19  Henri Moissan observed in 1893 that calcium carbide absorbed atmospheric nitrogen. In 1898, Fritz Rothe of Germany found that the compound formed by this absorption was calcium cyanamide. In the soil, calcium cyanamide decomposes to yield urea and ammonium carbonate, both potent fertilizers. A commercial process patented by Adolf Frank and Nikodem Caro for making calcium cyanamide from carbide was perfected in Germany in 1903 and was widely adopted almost immediately. This was the first commercial process that was used worldwide to fix atmospheric nitrogen. World output of calcium cyanamide
