Hydrogen Cyanide from Methanol – Chemical production and

Patents assigned to Nitto Chemical and Sumitomo Chemical indicate interest in a route to hydrogen via the catalytic ammoxidation of methanol. The present screening evaluation compares the costs of such a to those of manufacturing hydrogen by the ammoxidation of methane Andrussow technology
Cyanide destruction process using Sodium Hypochlorite

· The two-stage oxidation treatment first breaks down to cyanate at high pH. The cyanate is then destroyed at moderate pH. Either calcium hypochlorite granules or sodium hypochlorite may be used. For an automated system, the liquid hypo is used. Personal protective equipment: Gloves, apron, boots, goggles

Cyanide

A is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.. In inorganic cyanides, the group is present as the anion CN −. Salts such as sodium and potassium are highly toxic. Hydrocyanic acid, also known as hydrogen , or HCN, is a highly volatile
