Calcium oxide, Puratronic™, 99.998% (metals basis, excluding other alkaline earth and alkali metals 130ppm max), Thermo Scientific Chemicals

Description

Calcium oxide has wide-ranging utility in industry. It is used in making porcelain, cements, mortars, and glass. It is also employed in flue-gas desulfurization in power plants, purifying sugar, drying the solvents/reagents, preparing bleaching powder, calcium carbide, and calcium cyanamide. It also finds use in water softeners, chemical recovery at Kraft pulp mills, biodiesel production, and in petroleum industry for the detection of traces of water. In agriculture it is used to restore the pH of acidic soils (liming). It is useful as a basic catalyst & acid scavenger in several organic transformations, for example, in Arndt-Eistert Synthesis of alpha-diazoketones, synthesis of heterocycles and oximes.
