The Sodium Cyanide (NaCN) plant produces HCN from methane, ammonia and air. The HCN is then reacted with caustic soda (50% NaOH) to produce a sodium cyanide liquor of approximately 30 - 32% NaCN. The liquor is purified and diluted to 30% for sale. The plant is capable of producing approximately 18,000 tonnes per annum of HCN which is ...

Standard Operating Procedures for Sodium Azide (ABB467) Introduction: Sodium azide is a colorless crystalline inorganic salt. It is a very reactive and highly toxic chemical. Sodium azide decomposes oexplosively upon shock, concussion, heating (>275 C), or friction. Sodium azide reacts with various metals to form shock-sensitive compounds.

The procedures stated on how to test the CN- or NaCN are on point. Free cyanide can react to form HCN gas of which there will nolonger be free cyanide present to leach your gold or whichever commodity you will be targeting. I would recommend that you say you want to check your free cyanide rather than checking if whether cyanide has expired.

Potassium cyanide is a cyanide salt containing equal numbers of potassium cations and cyanide anions. It has a role as an EC 1.9.3.1 (cytochrome c oxidase) inhibitor, an EC 1.15.1.1 (superoxide dismutase) inhibitor and a neurotoxin. It is a cyanide salt, a one- carbon compound and a potassium salt.

This SOP covers substances which produce cyanide ion in solution and which display the high acute toxicity characteristics of cyanide. Organic cyano compounds which do not dissociate into cyanide ion (e.g., nitriles such as acetonitrile) and inorganic thiocyanates and cyanates exhibit much lower toxicity and do not need to be handled under this SOP.

The gas formed from sodium azide is less dense (lighter) than air, so it will rise. Sodium azide prevents the cells of the body from using oxygen. When this happens, the cells die. Sodium azide is more harmful to the heart and the brain than to other organs, because the heart and the brain use a lot of oxygen.
