Sodium cyanide is a poisonous compound with the formula Na C N. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a moderately strong base.
Quick ratio. In finance, the quick ratio, also known as the acid-test ratio, is a liquidity ratio that measures the ability of a company to use near-cash assets (or 'quick' assets) to extinguish or retire current liabilities immediately. It is the ratio between quick assets and current liabilities. A normal liquid ratio is considered to be 1:1.
Cyanogen bromide is the inorganic compound with the formula (CN)Br or BrCN. It is a colorless solid that is widely used to modify biopolymers, fragment proteins and peptides (cuts the C-terminus of methionine), and synthesize other compounds. The compound is classified as a pseudohalogen.
Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the −C≡N group is linked by a single covalent bond to carbon.
The reaction generally occurs between aromatic aldehydes or glyoxals, [ 1 ][ 2 ] and results in formation of an acyloin. In the classic example, benzaldehyde is converted to benzoin. [ 3 ] The benzoin condensation was first reported in 1832 by Justus von Liebig and Friedrich Wöhler during their research on bitter almond oil. [ 4 ]
v. t. e. A blood agent is a toxic chemical agent that affects the body by being absorbed into the blood. [ 1 ] Blood agents are fast-acting, potentially lethal poisons that typically manifest at room temperature as volatile colorless gases with a faint odor. [ 1 ] They are either cyanide - or arsenic -based.
The International Cyanide Management Code for the Manufacture, Transport and Use of Cyanide in the Production of Gold, commonly referred to as the Cyanide Code, is a voluntary program designed to assist the global gold and silver mining industries and the producers and transporters of cyanide used in gold and silver mining in improving cyanide management practices and to publicly demonstrate ...
One variation of the Bucherer–Bergs reaction is the treatment of carbonyl compound with carbon disulfide and ammonium cyanide in methanol solution to form 2,4-dithiohydantoins. [8] In addition, the reaction of ketones with ammonium monothiocarbamate and sodium cyanide will yield 5,5-disubstituted 4-thiohydantoins. [9]
