| Use | for removal of hydrogen sulfide and carbon dioxide from natural gas and refinery gas, for fiber additives, tanning agents, pesticides, cutting oil and other diisopropanolamine is used as an absorbent of acid gas, for example, to absorb CO2 and H2S in natural gas and petroleum refining gas, to remove CO2 in synthesis gas in ammonia industry, and to concentrate CO2 in dry ice production. In addition, it is also used for metal annealing, inert gas manufacturing, neutralization agent of electrophoretic coating, etc. In terms of emulsifier, the product is applied to fiber additives, tanning agents, pesticides, cutting oils, coatings and wax products. Diisopropanolamine reacts with fatty acids to produce fatty acid amides and lipids and is used as the active component of a shampoo. is an important organic intermediate, because it has hydroxyl and amine groups, it is widely used in the synthesis of fine chemicals such as pharmaceuticals, pesticides, detergents, cosmetics, etc, its largest use is as a desulfurization and decarbonization agent, widely used in the fertilizer industry, petrochemical and natural gas industries. |
| production method | propylene oxide reacts with ammonia to generate mono-isopropanolamine, and continues to react with propylene oxide to generate di-and tri-isopropanolamine. Propylene oxide and ammonia were mixed and then pre-heated to the reaction temperature and entered the reactor for reaction. The reaction product was first stripped to remove ammonia and water, and the ammonia was recycled. Then, the crude isopropanolamine is sent to a vacuum distillation system, and Monoisopropanolamine, diisopropanolamine and triisopropanolamine are fractionated into pure products. When the excess of propylene oxide in the raw material ratio is more, the proportion of triisopropanolamine in the obtained product increases. |
