Is MIBK methyl isobutyl ketone miscible with water?

Jan 04, 2026 Leave a message

Methyl Isobutyl Ketone (MIBK) CAS 108-10-1 is an organic compound that has a low odour and is referred to as an oxygenated solvent. The solvent is a clear, colourless liquid and has a low flash point at 15°C with a specific gravity of 0.8. The product is stable at room temperature and pressure. MIBK solvent is a product soluble in polar and non-polar organic solvents making it perfect in using for reducer formulations and coatings. Additionally, the characteristic of MIBK has a slower evaporation rate which will mean that it will have a premium gloss finish in coatings.

Is MIBK methyl isobutyl ketone miscible with water?

Methyl isobutyl ketone MIBK is not miscible with water. It has low solubility in water (approximately 2% by weight at 20°C). When mixed, it will form a separate layer. This property is exploited in liquid-liquid extraction processes in chemical manufacturing. MIBK (CAS 108-10-1) is, however, fully miscible with most organic solvents, including alcohols, ethers, hydrocarbons, and esters.

 

What is MIBK used For?

4-Methyl-2-pentanone MIBK can be used as a solvent in organic synthesis reactions, especially in the extraction and separation of plant extracts.
