Triisopropanolamine is a chemical compound from the group of amino compounds and alcohols .

Extraction and presentation

Triisopropanolamine can be obtained by reacting ammonia with propylene oxide , whereby it is formed from diisopropanolamine preferably at a low concentration of ammonia (i.e. excess of propylene oxide over ammonia).

properties

Triisopropanolamine is a flammable, hygroscopic yellow solid with a faint odor, which is easily soluble in water. Its aqueous solution has an alkaline reaction.

use

Triisopropanolamine is used as an absorbent for carbon dioxide or hydrogen sulfide, as a neutralizing agent in the production of polyurethane foams, as a corrosion inhibitor in lubricating and cutting oils, as a mold release agent, PVC additive, finishing agent for textiles and as a coating agent for paper and wood. It is contained in lacquers and developers (copier systems).

It is used as a grinding aid in cement production , especially for high-quality cement types. It is also used as a dispersant in paints and pigments such as titanium dioxide.
