DESCRIPTION AND APPLICATIONS
There are three isopropanolamines called mono, di and tri-propanolamine with formula with formula CH3CH(OH)CH2NH2, CH3CH(OH)CH2]2NH, and CH3CH(OH)CH2]3N respectively. Monoisopropanolamine is a liquid at room temperature, while diisopropanolamine and triisopropanolamine are white solids. Isopropanolamine is a clear to yellow, corrossive, combustible liquid with a faint ammonia odor; boils at 159.9 C. It is soluble in water and very soluble in benzene and ether. Diisopropanolamine is a clear to yellow hygroscopic crystalline lumps; boils at 241 C, decomposes on heating producing toxic nitrogen oxides. It is a medium strong base and reacts violently with strong oxidants. It turns yellow when exposed to light and air. Diisopropanolamine and triisopropanolamine are commercially available in liquid grades contain deionized water typically 15%. These liquid grades should not be stored in the presence of aluminum due to the possibility of excessive corrosion and potential chemical reaction releasing flammable hydrogen gas at above 60 C. Isopropanolamines are used as an absorbent of acid gases in the refinery of natural gas and purification of ammonia. They are used as an emulsifying agent soluble in water and low alkalinity. They are used as a crosslinking catalyst in the production of polyurethanes. They are used as a component of insecticide, surfactants, rubber chemicals, corrosion inhibitors and pigment dispersants.

Isopropanolamines have applications in the field of:  

  • Gas-scrubber
    • Natural and refinery gas operations
    • Hydrogen sulfide (H2S) and CO2 gas removal
