Hydrogenated cyanamide
WebOverview. Hydrogen cyanide (HCN) is a colorless or pale-blue liquid or gas with a bitter, almond-like odor. Hydrogen cyanide interferes with the body’s use of oxygen and may cause harm to the brain, heart, blood vessels, and lungs. Exposure can be fatal. Workers may be harmed from exposure to hydrogen cyanide. WebThis preliminary note concerns the use of calcium cyanamide as a fertiliser and its potential to pose an unacceptable risk to human health and/or the environment. Calcium cyanamide is listed in Annex I to Regulation (EC) No 2003/2003 as an EC fertiliser and hence benefits from free circulation in the Single Market. Under REACH, the substance is

Web31 aug. 2024 · Under inadequate chilling conditions, hydrogen cyanamide (HC) is often used to promote budbreak and improve earliness of Southern highbush blueberry ( Vaccinium corymbosum L. interspecific hybrids). However, HC is strictly regulated or even banned in some countries because of its high hazardous properties. Cyanamide is produced by hydrolysis of calcium cyanamide, which in turn is prepared from calcium carbide via the Frank-Caro process. CaCN2 + H2O + CO2 → CaCO3 + H2NCN The conversion is conducted on slurries.
