Calcium Carbide Powder

Calcium Carbide Powder

The potential applications of calcium carbide are not limited to the known reactions of acetylene and may eventually lead to the development of new transformations of the ethynyl group. The unique nature of this small molecule is already beginning to manifest. This review provides a brief overview of the subject based on selected references. The main focus is on organic chemistry applications while a brief note is made on the potential use of Calcium carbide powder in system preparation as this area is now actively being developed. Calcium carbide powder has been used in conventional organic synthesis to irreversibly remove water from reaction mixtures. However, the use of aqueous solvents to generate acetylene in situ opens new perspectives for alkyne chemistry. The unique properties of calcium carbide, discussed in the previous section, also determine its use as a denitrifying agent. Soil denitrification is the rapid conversion of ammonium nitrogen in fertilizers into nitrate. This process is made possible by the bacteria in the soil. The resulting nitrates are toxic, but are quickly removed from the soil. When used in conjunction with fertilizers, encapsulated calcium carbide reduces the activity of soil bacteria, improving ammonium nitrogen binding by plants and increasing yields. Waxy materials are commonly used as encapsulating agents. The encapsulation delays the hydrolysis of calcium carbide for several days, even in moist soils. Calcium carbide is more active in some soils than standard denitrification inhibitors. In addition, calcium carbide and its hydrolysis products are non-toxic to the environment. All these facts show that Calcium carbide powder is a promising agent for denitrification inhibition.
