Phosphorus trichloride facilitates the conversion of hydroxyl groups in drug molecules into phosphoramidate esters, enhancing their efficacy and delivery mechanisms in the human body.
⚗️ Chemical & Physical Properties
Phosphorus trichloride is a colorless to yellow liquid with a pungent, suffocating odor. The compound is highly reactive and should be handled with caution due to its tendency to fume in moist air.
With a molar mass of 137.33 g/mol and a density of 1.574 g/cm³ at 20°C, Phosphorus trichloride is heavier than common food items such as water and sugar. Its density is comparable to olive oil, which has a density of around 0.92 g/cm³.
Phosphorus trichloride has a melting point of -76.3°C and a boiling point of 76.1°C. These values are significantly lower than those of common food items like butter and chocolate, which have much higher melting and boiling points.
Phosphorus trichloride is insoluble in water, but it reacts vigorously with water to form hydrochloric acid and phosphorous acid. The compound has low viscosity, unlike items such as honey or syrup, which are much more viscous.
🏭 Production & Procurement
Phosphorus trichloride is typically produced by reacting white phosphorus with chlorine gas in a reaction vessel. The exothermic reaction produces a mixture of phosphorus trichloride and phosphorus pentachloride, which can be separated through fractional distillation.
Phosphorus trichloride can be procured commercially from chemical suppliers that specialize in industrial chemicals. It is commonly available in sealed containers to prevent contact with moisture and air, as it is highly reactive. Transportation of Phosphorus trichloride is typically done in specialized containers that are resistant to corrosion and leakage to ensure safe handling.
In the process of procurement, proper precautions should be taken to ensure the safety of personnel handling Phosphorus trichloride. This includes wearing appropriate personal protective equipment such as gloves, goggles, and lab coats. Additionally, Phosphorus trichloride should be stored in a cool, dry place away from incompatible materials to prevent any accidents or chemical reactions.
⚠️ Safety Considerations
Safety considerations for Phosphorus trichloride, a highly reactive chemical compound, must be thoroughly understood and adhered to when handling. It poses a significant risk of serious eye and skin irritation upon contact, as it can react violently with moisture to release toxic fumes. Additionally, exposure to Phosphorus trichloride may result in respiratory issues, such as difficulty breathing or coughing, and can lead to severe burns if not handled properly.
Hazard statements for Phosphorus trichloride include “causes severe skin burns and eye damage” and “reacts violently with water.” These statements convey the potential dangers of working with this compound, emphasizing the need for proper protective equipment and handling procedures to prevent harm. It is crucial for individuals handling Phosphorus trichloride to be aware of these hazard statements and take appropriate precautions to minimize the risk of injury.
Precautionary statements for Phosphorus trichloride include “wear protective gloves/eye protection/face protection” and “do not breathe dust/fume/gas/mist/vapors/spray.” These statements outline specific measures that should be taken to ensure safe handling of the compound, such as wearing appropriate personal protective equipment and avoiding inhalation of potentially harmful substances. Following these precautionary statements is essential for maintaining a safe working environment when dealing with Phosphorus trichloride.
