Methyl Isobutyl Carbinol CAS NO.CAS 108-11-2
Product Introduction
Methyl Isobutyl Carbinol (MIBC, CAS 108-11-2) is a high-performance specialty chemical widely recognized for its excellent frothing performance, low volatility, and strong stability. It is extensively used in mineral flotation, industrial solvents, and chemical intermediates, delivering efficient separation and reliable industrial processing results.
Methyl Isobutyl Carbinol (CAS NO.CAS 108-11-2) Product Overview
Methyl Isobutyl Carbinol (MIBC), with the molecular formula C6H14O and CAS No. 108-11-2, is a colorless, transparent organic compound with a mild odor. As an important specialty chemical and chemical intermediate, MIBC is primarily used as an efficient frother in mineral flotation processes, particularly in copper, molybdenum, coal, and non-ferrous metal beneficiation. In addition, it is widely applied as an industrial solvent, chemical auxiliary, and raw material in coatings, lubricants, and resin production due to its excellent chemical stability and low water solubility.

Advantages – Why choose our MIBC
Higher selectivity than pine oil or aliphatic alcohols:
MIBC produces fine, brittle bubbles that burst quickly after rising, reducing mechanical entrainment of gangue minerals → improves concentrate grade.
Consistent foaming performance:
Our narrow boiling range ensures predictable froth characteristics across different ore types and water conditions.
Low odor compared to traditional frothers:
Creates a safer, more pleasant working environment for flotation operators.
Excellent chemical stability:
Does not hydrolyze or react with common collectors (xanthates, dithiophosphates) under normal flotation pH ranges
Benefits – What the customer gains
For mining and mineral processing plants:
MIBC increases recovery of valuable minerals (Cu, Mo, Au, Pb, Zn) by 1–5% compared to pine oil, while maintaining or improving concentrate grade → directly translates to higher revenue per ton of ore processed.
01
For flotation reagent formulators:
MIBC can be used alone or blended with other frothers (e.g., DF-250, Dowfroth 200) to fine-tune bubble size and froth stability → flexible formulation capabilities.
02
For coating and ink manufacturers (specialty use):
As a slow-evaporating solvent, MIBC improves leveling and film formation in high-solids coatings → reduces surface defects and orange peel.
03
For organic synthesis:
MIBC serves as a precursor to plasticizers, lubricant additives, and metalworking fluid components → value-added derivative opportunities.
04
