Uses: hexamethylphosphoryltriamine is a new chemical product with extensive use and good performance in recent years, which is widely used in national economic production activities such as rubber, textile printing and dyeing, aviation reagents, etc., but the operating conditions in its synthesis process have a certain risk of Chemicalbook. For example, the raw materials used in the synthesis of hexamethylphosphoryltriamine, such as phosphorus oxychloride and xylene, have highly toxic and flammable properties and acute toxicity. Moreover, higher heating temperature is needed in the synthetic reaction process, which is easy to cause secondary reaction and cause accidents.
