potassium Ethyl Xanthate
Molecular Formula: C₃H₅KOS₂
Molecular Weight: 160.1
Potassium ethyl xanthate is a commonly used sulfide ore beneficiation reagent, and it can also be used in chemical analysis and organic synthesis. It is generally a pale yellow crystalline powder, with pure ingredients and few impurities. It is suitable for various scenarios such as mine flotation and laboratory testing, and is stable and convenient to use in daily operations. It is synthesized from ethanol, carbon disulfide, and potassium hydroxide, with strict purity control. It is not prone to caking or deterioration, and the alkalinity of the aqueous solution is moderate, making it highly compatible for use.
- Appearance: A white or pale yellow crystalline powder or granular solid, possessing a pungent, sulfide-like odor.
- Solubility: Highly soluble in water; soluble in ethanol; insoluble in non-polar organic solvents such as benzene and gasoline. Aqueous solutions are weakly alkaline.
- Stability: Stable under dry conditions at ambient temperature; highly hygroscopic. It decomposes readily upon contact with strong acids, yielding carbon disulfide, ethanol, and sulfides; exposure to heat, moisture, or direct sunlight accelerates its decomposition and loss of efficacy.
- Chemical Properties: Classified as an anionic thiol-based collector; in mineral slurries, it readily dissociates to release xanthate ions, thereby exerting an adsorptive effect on sulfide minerals.
- Other: Exhibits a certain degree of hygroscopicity; it is combustible, and thermal decomposition at high temperatures generates toxic fumes containing sulfur oxides.
Safety, Storage, and Transport
Irritating: Avoid irect contact with skin and the respiratory tract. Upon contact with acids, it releases toxic carbon disulfide gas.
Storage: Store in a cool, well-ventilated, and dry environment; protect from moisture and light, and keep sealed. Keep away from strong acids and strong oxidizing agents.
Transport: Handle in accordance with regulations for general industrial chemicals. Strictly avoid exposure to rain or direct sunlight, and strictly prohibit co-transport with acidic materials.
