Properties and Usage:
Sodium thiocyanate is a chemical raw material with the appearance of colorless or white crystalline powder, which is used in chemical analysis, pharmaceutical industry, industrial production and agricultural environment.
1. Chemical analysis
Analytical reagent: Sodium thiocyanate can be used to detect iron ions (Fe³⁺). When reacting with iron (III) chloride, it forms deep red iron (III) thiocyanate.
Coordination chemistry: Sodium thiocyanate participates in the synthesis of various metal complexes as a ligand, helping to study the coordination behavior of different metal ions
2. Pharmaceutical industry
In some cases, sodium thiocyanate can be used as an antidote to neutralize cyanide poisoning
3. Industrial application
Coolant: Due to the high solubility of sodium thiocyanate in water, it can effectively absorb heat and optimize the cooling process, and is often used as a coolant in industrial cooling systems.
Textile industry: It is used in the production of dyes and the treatment of textiles to improve the color fastness and processing efficiency of products.
4. Agriculture and environment
Pesticide intermediate: As an intermediate in the synthesis of certain pesticides, sodium thiocyanate can improve crop protection performance.
Wastewater treatment: Sodium thiocyanate is used as a decyanating agent to remove cyanide from wastewater and reduce its toxicity.
Storage conditions: Store in a cool, dry place. Keep away from moisture, do not press, and avoid opening the lid and breaking the barrel.
Packing: This product is packed in 25kg bags, and it can also be customized according to customers' requirements
