cyanide fusant - Physico-chemical Properties
Molecular Formula | CN-
|
Molar Mass | 26.0174 |
Physical and Chemical Properties | Grayish-black flaky, powder or block product. The relative density of 1.8~1.9. It is a mixture of various solids after melting, mainly containing calcium cyanide, sodium chloride and calcium oxide and other substances, in which cyanide is dissolved in water. Pure white crystals. Since the decomposition started above 350 °c, the melting point was determined to be around 640 °c by extrapolation. Cyanide is predominantly present in the cyanide melt as calcium cyanide. The calcium cyanide solution can be obtained by leaching the cyanide melt with water. With acid to produce hydrogen cyanide. In the air, cyanide melt absorption of carbon dioxide and water vapor, decomposition to produce hydrogen cyanide, resulting in a significant decline in product quality. Highly toxic! |
cyanide fusant - Introduction
Cyanide frit, also known as cyanide melt, is a high concentration solution of cyanide, usually sodium cyanide or potassium cyanide solution. The following is an introduction to the nature, use, preparation and safety information of cyanogen frit:
Nature:
1. Cyanogen frit is a colorless or yellowish liquid with a pungent smell of ammonia.
2. It has a high degree of solubility and can be dissolved in water or organic solvents.
3. Smudge on metal will quickly corrode and erode.
Use:
1. Cyanide frit is mainly used in metal electroplating and electroplating process, and can be used as a component of electroplating solution.
2. It can also be used to prepare some compounds in organic synthesis, such as cyanide or cyanate.
Preparation Method:
Generally, the cyanide frit is obtained by adding sodium cyanide or potassium cyanide to water, stirring and heating to dissolve. The preparation process requires strict safety measures and equipment.
Safety Information:
1. Cyanogen frit is highly toxic substances, must be careful, and follow the safe operation procedures.
2. It has serious harm to human body and environment, especially inhalation and contact. Therefore, personal protective equipment such as protective glasses, gloves and protective clothing must be worn for operation.
3. When using cyanide frit, it must be carried out in a well-ventilated place, and the concentration and usage of the solution must be strictly controlled.
4. Cyanide frit must be stored in a closed container, away from heat and fire sources, and stored separately from acids and oxidants.
