Product Description

Chemical properties
Colorless to pale yellow liquid

Usage:
Used as pharmaceutical raw materials, solvent for photographic developer, solvent for paraffin oil in rayon, emulsifier for cosmetics, etc.

Triisopropanolamine can be used as gas absorbent and antioxidant; as grinding aid in cement industry; as refining agent, antistatic agent, dyeing aid, fiber wetting agent in fiber industry; in lubricating oil and cutting oil It can be used as antioxidant and plasticizer; as a cross-linking agent in the plastic industry; it can also be used as a dispersant for titanium dioxide, minerals, and a curing agent in the polyurethane industry.

Uses are mainly used for the synthesis of intermediates, and as a chain extender on PU and as a neutralizing agent on daily chemicals.

The production method uses liquid ammonia and propylene oxide as raw materials, uses water as a catalyst, prepares materials according to the molar ratio of liquid ammonia and propylene oxide as  3.00~3.05, and adds deionized water at one time, and the dosage ensures that the concentration of ammonia water is 28~ 60%; liquid ammonia and propylene oxide are divided into two feeds, each time first add half the amount of liquid ammonia, keep the temperature at 20 ~ 50 ºC, then slowly add half the amount of propylene oxide, stir well, and keep the kettle The internal pressure is below 0.5 MPa, the reaction temperature is 20 to 75 ° C, and is maintained for 1.0 to 3.0 hours; after the addition of propylene oxide, the temperature of the reaction kettle is controlled to 20 to 120 ° C, and the reaction is continued for 1.0 to 3.0 hours. When the water content is less than 5%, a triisopropanolamine product is obtained. The method can effectively suppress the production of monoisopropanolamine and diisopropanolamine, has simple process and low investment cost.
