Hexamethylphosphoramide, often abbreviated HMPA, is a phosphoramide (an amide of phosphoric acid) with the formula [(CH3)2N]3PO. This colorless liquid is a useful reagent in organic synthesis.
Hexamethylphosphoric triamide, also known as hexaphosphoramine and hexamethylphosphoramide, is prepared by the reaction of dimethylamine and phosphorus oxy-chloride. The molecular weight is 179.2. It is a colorless or light yellow transparent liquid. Slightly fishy and astringent. The relative density is 1.0253~1.0257 (20ºC), the refractive index is 1.4582~1.4589 (20ºC), the freezing point is 2Chemicalbook~7ºC, and the boiling point is 116~117ºC (1480Pa). Soluble in polar and non-polar solvents. It can be miscible with commonly used plasticizers such as dioctyl phthalate, dioctyl sebacate, and triphenyl phosphite in any ratio. The toxicity is similar to that of phosphate. Avoid contact with skin. The container should be tightly closed to prevent damage, leakage, and deterioration of water absorption.
Hexamethylphosphoric triamide is a new chemical product with versatility and good performance in recent years. It is widely used in national economic production activities such as rubber, textile printing, and dyeing, aviation reagents, etc. However, the operating conditions of its synthesis process Etc. have a certain degree of danger from the Chemical book. For example, the raw materials used in the synthesis of hexamethyl phosphoric triamide, phosphorus oxy-chloride, and xylene, are highly toxic and flammable and are acutely toxic. Moreover, a higher heating temperature is required in the synthesis reaction process, which is easy to cause secondary reactions and cause accidents.
