Tris(pyrrolidinophosphine) oxide - Introduction
Tris (N,N-tetramethylene)phosphoric acid triamide is an organophosphorus compound with the chemical formula [(CH2)4N]3PO3. It is a colorless liquid, has a pungent odor, and is soluble in water and organic solvents. The following is an introduction to the nature, use, formulation and safety information of tris(N,N-tetramethylene)phosphoric acid triamide:
Nature:
- tris(N,N-tetramethylene)phosphoric acid triamide is a strong base that can neutralize acids and form salts.
-It has good thermal stability and oxidation stability.
-In water, it can form hydrogen bonds and coordinate with metal ions.
Use:
- tris(N,N-tetramethylene)phosphoric acid triamide is often used in organic synthesis reactions as a base catalyst.
-It can be used as a polymer additive to improve the thermal stability and weather resistance of the polymer.
- tris(N,N-tetramethylene)phosphoric acid triamide can also be used in ligand synthesis, catalyst preparation and chemical analysis.
Preparation Method:
- tris(N,N-tetramethylene)phosphoric acid triamide can be obtained by a three-step synthesis. First, phosphorus trichloride is reacted with tetraethylenediamine to give tris (N,N-diethyl) phosphoramide. Tris (N,N-diethyl) phosphoramide is then oxidized with sodium hydroxide under basic conditions to give tris (N,N-diethoxy) phosphoramide. Finally, tris(N,N-diethoxy) phosphoramide is reacted with acetaldehyde to give tris(N,N-tetramethylene)phosphoric acid triamide.
Safety Information:
-Because tris(N,N-tetramethylene)phosphoric acid triamide is a strong base, contact with skin and eyes will cause irritation. Wear protective gloves and goggles during operation and avoid inhalation of gases or solutions.
- tris(N,N-tetramethylene)phosphoric acid triamide should be stored in a sealed container, away from ignition and oxidizing agents.
-Follow proper laboratory practices and safe operating procedures when using or handling this compound.
