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 Textile Operation Softeners Lubricants Dye Leveling Agents Dispersants Durable Press Optical Brighteners Surfactants and  Metalworking fluids Impart alkalinity Detergents Cosmetic formulations Acid neutralization Fatty acid soaps Emulsifiers Corrosion Inhibitors Others Concrete grinding aid Cement admixture Urethane foams Agricultural products Photographic chemicals Biocides Oil well chemicals Rubber vulcanization accelerators Plasticizers Pigment Dispersant Cross-Linker for Coatings Asphalt aggregatation MIPA DIPA TIPA Formula CH3CH(OH)CH2NH2 [CH3CH(OH)CH2]2NH [CH3CH(OH)CH2]3N MW (75.11) 133.19 191.27 CAS RN 78-96-6 110-97-4 122-20-3 Appearance Clear liquid clear to light yellow crystals Specific Gravity 0.96 1.015 1.02 Freezing Point C 3 - 4 C 44 - 45 C 48 - 52 Boiling point C 159 248 - 249 305 C Flash Point C 73 135 160 SALES SPECIFICATION 85% AQ.SOLUTION APPEARANCE clear to light yellow liquid CONTENT 85.0% min WATER Balance TRANSPORTATION PACKING 200kgs in drum HAZARD CLASS UN NO.
