2-Ethylhexanol (Flotation Solvent / Frother)
CAS Number: 104-76-7
2-Ethylhexanol is a branched-chain C8 alcohol used as a co-frother, collector solvent, and flotation aid in mineral processing. Its moderate frother activity and low water solubility make it a useful extender for primary frothers such as MIBC, improving froth stability and bubble size distribution in fine-particle flotation. It is also used as a solvent to dissolve and disperse sparingly soluble collectors (such as fatty acids and kerosene) for improved conditioning efficiency.
