use | used as pharmaceutical raw materials, solvent for photo developer, solvent for paraffin oil in man-made fibers, emulsifier for cosmetics, etc. triisopropanolamine can be used as gas absorbent and antioxidant; Cement industry is used as grinding aid; Fiber industry is used as refining agent, antistatic agent, dyeing aid and fiber wetting agent; Used as antioxidant and plasticizer in lubricating oil and cutting oil; the plastic industry is used as a crosslinking agent; it can also be used as a dispersant for titanium dioxide, minerals, and a curing agent in the polyurethane industry. It is mainly used for the synthesis of intermediates, as a chain extender on PU and as a neutralizing agent on daily chemicals. |
production method | liquid ammonia and propylene oxide are used as raw materials, water is used as catalyst, materials are prepared according to the molar ratio of liquid ammonia to propylene oxide of 1: 3.00~3.05, deionized water is added at one time, and the dosage ensures that the concentration of ammonia water is 28 ~ 60%; Liquid ammonia and propylene oxide are divided into secondary feeding, and half of the amount of liquid ammonia is added first each time, keep the temperature at 20~50 ℃, then slowly add half of the amount of propylene oxide, fully stir, and keep the pressure in the kettle below 0.5MPa, the reaction temperature is 20~75 ℃, and maintain for 1.0~3.0 hours; After adding propylene oxide, control the temperature of the reaction kettle to 20~120 ℃, make it continue to react for 1.0~3.0 hours, dehydrate under reduced pressure until the water content is less than 5%, and obtain triisopropanolamine product. The method can effectively produce one isopropanolamine and diisopropanolamine, the process is simple, the investment cost is low. |
