N,N-BIS(2-HYDROXYETHYL)ISOPROPANOLAMINE NEW

N,N-Bis(2-hydroxyethyl)isopropanolamine (chemical formula C₇H₁₇NO₃) is a tertiary amino alcohol with the following structural features:

Chemical Structure

• Core: Tertiary amine nitrogen (N) bonded to three groups:

• One isopropyl group (–CH(CH₃)₂)

  Two 2-hydroxyethyl groups (–CH₂CH₂OH)

• Systematic Name: *1-[Bis(2-hydroxyethyl)amino]-2-propanol* or *N-(1-Hydroxypropan-2-yl)diethanolamine*.

• Molecular Weight: 163.22 g/mol.

Key Properties

• Physical State: Colorless to pale yellow viscous liquid.

• Hydrophilicity: Miscible with water due to three hydroxyl (–OH) groups.

• Reactivity: Combines tertiary amine (base) and alcohol functionalities.

Primary Applications

Concrete Additives:

• Grinding aid in cement production (improves mill efficiency and powder flow).

  Surfactants & Emulsifiers:

• Precursor for cationic surfactants (e.g., quaternary ammonium compounds).

  Corrosion Inhibitors:

• Used in metalworking fluids and coolants.

  Pharmaceutical/Chemical Synthesis:

• Building block for drug intermediates and chelating agents.

Safety & Handling

• Irritant: Causes skin/eye irritation.

• Low volatility: High boiling point (~250–300°C).

• Storage: Keep in sealed containers away from strong oxidizers.

Summary: A multifunctional amino alcohol primarily used in cement grinding aids and specialty surfactants. Its triple hydroxyl/amine structure enables chelation and surface activity.
