  • Diisopropanolamine（DIPA）

Diisopropanolamine（DIPA）

Diisopropanolamine (DIPA), with the chemical formula C₆H₁₅NO₂, is an important alkanolamine compound. It appears as a white crystalline solid at room temperature and transforms into a colorless to light yellow viscous liquid above 42°C. It has a slight ammonia odor and is soluble in water and various organic solvents. The molecule contains one secondary amino group and two secondary hydroxyl groups, giving it both amine and alcohol characteristics. It is widely used in gas purification, surfactants, corrosion inhibitors, and plays a key role in selective desulfurization processes.

Main Applications


  1. Gas Treating: Key component in gas sweetening processes for natural gas and refinery gases, used for selective removal of hydrogen sulfide (H2S) while retaining carbon dioxide (CO2).

  2. Surfactants: Intermediate for producing emulsifiers, foam stabilizers, and thickeners used in personal care products and detergents.

  3. Metalworking: Effective corrosion inhibitor and pH stabilizer added to cutting fluids, grinding fluids, and rust preventive formulations.

  4. Textile Industry: Used in the production of textile auxiliaries, such as softeners and dye dispersants.

  5. Rubber Industry: Intermediate for the production of rubber vulcanization accelerators.

  6. Cement Grinding Aids: Used as a raw material to improve the efficiency of cement grinding.

Safety Precautions


  1. Health Hazards:
    · Causes severe skin burns and eye damage
    · Inhalation of dust or vapour may cause respiratory irritation
    · Harmful if swallowed, causes burns of the digestive tract
    · Prolonged or repeated skin contact may cause dermatitis

  2. Handling Protection:
    · Wear chemical safety goggles, impermeable gloves, and protective clothing
    · Ensure adequate ventilation in the operating area. Avoid breathing dust or vapour
    · Avoid contact with skin and eyes
    · Wash hands thoroughly after handling

  3. Storage & Transportation:
    · Store in a cool, dry, well-ventilated area
    · Keep containers tightly closed to prevent moisture absorption
    · Store separately from strong oxidizers and strong acids
    · Use stainless steel or epoxy-lined containers

  4. Fire Fighting:
    · Combustible solid/liquid. Flash point 126°C (closed cup)
    · Use water spray, foam, dry powder, or CO2 to extinguish fire
    · Use water spray to cool exposed containers and prevent re-ignition
