                               Triisopropanolamine Usage And Synthesis

Description

Triisopropanolamine (TIPA), a tertiary alkanolamine, is majorly used as a grinding chemical that reduces agglomeration in the ball milling process and changes the particle distribution of the finished cement.

N,N-Diethylpropynamine, with the chemical formula C7H13N, is an organic compound. Its molecular structure contains two ethyl groups and one propynyl group, which are connected through a nitrogen atom. This structure gives N,N-diethylpropynamine some unique chemical properties, such as strong basicity, good solubility, and reactivity. The synthesis of N,N-diethylpropynamine is usually carried out by reacting propynol with diethylamine under the action of a catalyst. This reaction process requires precise control of reaction conditions, such as temperature, pressure, type and dosage of the catalyst, etc., to ensure the purity and yield of the product. In the laboratory, scientists have successfully synthesized high-purity N,N-diethylpropynamine through continuous experimentation and optimization of reaction conditions, laying the foundation for subsequent research and applications.

Usage

Triisopropanolamine can be used as a gas absorbent and antioxidant; Used as grinding aids in the cement industry; Fiber industry uses it as a refining agent, anti-static agent, dyeing assistant, and fiber wetting agent; Used as antioxidant and plasticizer in lubricating oil and cutting oil in RunChemicalbook; Used as crosslinking agent in the plastic industry; It can also be used as a dispersant for titanium dioxide and minerals, as well as a curing agent in the polyurethane industry

Chemical properties

Triisopropanolamine is a white to slightly yellow crystalline that is almost odorless. It is fully soluble in water. It is a corrosive and hygroscopic solid.

Synthesis

Using liquid ammonia and epichlorohydrin as raw materials, water as a catalyst, prepare materials in a molar ratio of 1:3.00-3.05 between liquid ammonia and epichlorohydrin, and add deionized water at once, ensuring that the concentration of ammonia water is 28-60%; Liquid ammonia and epichlorohydrin are evenly divided into secondary feeding. Half of the liquid ammonia is added each time, and the temperature is maintained at 20-50 ℃. Then, half of the epichlorohydrin is slowly added, stirred thoroughly, and the pressure inside the kettle is kept below 0.5MPa. The reaction temperature is maintained at 20-75 ℃ for 1.0-3.0 hours; After adding epichlorohydrin, control the temperature of the reaction kettle at 20-120 ℃ and continue the reaction for 1.0-3.0 hours. Dehydrate under reduced pressure until the water content is less than 5% to obtain the product of triisopropanolamine. This method can effectively produce monoisopropanolamine and diisopropanolamine, with a simple process and low investment cost.
