Methyl isobutyl ketone (MIBK), CAS No.:108-10-1, is the organic compound with the formula (CH3)2CHCH2C(O)CH3. This colourless liquid, a ketone, is widely used as a solvent. Acetone and hydrogen are the raw materials for MIBK production.

CWB Two-Step MIBK Technology

Process Highlights:

  • CWB's first patented process, US Patent No.: US 9,120,734.
  • A two-step process: Step 1: aldol condensation (aldol+dehydration), Step 2: Hydrogenation
    • Lower operation pressure than the conventional one-step or three-step process
    • Acetone is separated before hydrogenation, hence unreacted acetone hydrogenation to give isopropanol as a byproduct can be avoided.

Economics:

  • Huge reduction in catalyst cost compared to existing one-step process
  • Lower operation pressure hence reduced capital investment for process equipment
  • Competitive raw material consumption compared to existing processes
  • Reduced energy consumption through heat integration and optimised purification process

Safety and Environment:

  • Reduced risk in operation due to lowered pressure requirement
  • Less polymeric waste (ion-exchange resin) is generated
