Potassium N-Pentyl Xanthate
Molecular Weight: 202.0
Pentyl xanthate potassium is a powerful collector for mineral separation flotation agents. It is mostly in a light yellow powder form and is specifically designed for flotation scenarios of refractory sulfide and oxide ores. It is synthesized by combining n-pentanol, dithiocarbonic acid, and potassium hydroxide.

Molecular Formula: C6H11KOS2
Molecular Weight: 202.0
Pentyl xanthate potassium is a powerful collector for mineral separation flotation agents. It is mostly in a light yellow powder form and is specifically designed for flotation scenarios of refractory sulfide and oxide ores. It is synthesized by combining n-pentanol, dithiocarbonic acid, and potassium hydroxide. The raw material ratio is well balanced, impurities are strictly controlled, and it has good stability in alkaline environments. It can be adapted to various mining and mineral separation working conditions and is easy to operate in daily practice.
- Appearance: A pale yellow to yellow-green crystalline powder or granules, possessing the characteristic pungent sulfurous odor typical of xanthates.
- Solubility: Readily soluble in water and ethanol; aqueous solutions exhibit weak alkalinity. Sparingly soluble in non-polar solvents such as hydrocarbons and benzene.
- Hygroscopicity and Stability: Stable under dry, sealed conditions at ambient temperature. Highly hygroscopic; prone to caking and decomposition upon moisture absorption. Rapidly decomposes upon contact with strong acids, releasing toxic carbon disulfide gas. High temperatures, direct sunlight exposure, and high-humidity environments accelerate degradation.
- Flotation Performance Characteristics: Exhibits extremely strong collecting power, though its selectivity is relatively weak. Foaming properties are moderate. Characterized by a long carbon chain and strong hydrophobicity; its adsorption capacity for sulfide ores is significantly higher than that of ethyl or butyl xanthates.
Safety, Storage, and Transport
Irritating substance; avoid direct contact with skin, eyes, and the respiratory tract. It releases toxic carbon disulfide upon contact with acids; co-storage with strong acids is strictly prohibited.
Storage: Store in a cool, well-ventilated, and dry environment; keep containers tightly sealed, protected from moisture and light, and away from oxidizers and acids.
Transport: Handle in accordance with regulations for industrial hazardous chemicals; protect from rain and direct sunlight. Co-loading and transport in the same vehicle with acidic or strongly oxidizing goods is prohibited.
