Jan 04, 2026 Leave a message

CAS 108-10-1 Methyl isobutyl ketone (MIBK) is a colorless organic compound with a pleasant odor. It is a solvent that is widely used in various industrial applications due to its excellent solvency properties and moderate evaporation rate.

MIBK chemical is produced by four different routes: a three-step process via diacetone alcohol and mesityl oxide intermediates; a one-step process from acetone and hydrogen; a one-step process from isopropyl alcohol; and a single or multistep mixed feed process.
