In this way, the main technical specifications and labels (product parameters) of phosphorus bromide are obtained to be used in the right way, to ensure safety and to promote business.

The method of making phosphorus bromide is related to the raw material and production process, reaction steps and catalytic mechanism. Take red phosphorus as raw material and mix it with liquid bromine in an appropriate ratio. First put red phosphorus in the reactor, and then slowly inject liquid bromine. The reaction step is that the two contact at the beginning, and the phosphorus atom interacts with the bromine atom to react violently to generate phosphorus tribromide. The reaction formula is: $2P + 3Br_ {2} = 2PBr_ {3} $. This process needs to be controlled at temperature to prevent overreaction. As for the catalytic mechanism, a small amount of water or iodine can be used to catalyze to accelerate the reaction process and increase the yield. In this way, according to the raw material and process, reaction steps and catalytic mechanism, phosphorus bromide can be prepared.

Phosphorus tribromide (Phosphorus tribromide) is a chemical commonly used in chemical research. Its preparation and use must follow strict safety and operating practices to ensure the safety of the experimenter and the smooth progress of the experiment.
Phosphorus tribromide is corrosive and has strong irritation to the skin, eyes and respiratory tract. If it is inadvertently contacted, it will burn lightly and endanger life in severe cases. Therefore, when the experimenter operates, it is necessary to wear protective clothing, protective gloves and goggles, and in a well-ventilated place to prevent inhalation of harmful gases.
In terms of operating specifications, when using phosphorus tribromide, it is necessary to use dry and clean utensils to avoid the mixing of moisture and impurities. Due to its violent reaction with water, hydrogen bromide gas and phosphoric acid are formed, which not only damages the medicine, but also causes danger. When preparing the solution, phosphorus tribromide should be slowly added to the solvent, and stirred while adding, to prevent local overheating or the reaction from getting out of control.
Storage of phosphorus tribromide should not be ignored. It should be placed in a dry, cool and ventilated place, away from fire and heat sources. At the same time, it should be stored separately from oxidizing agents and alkalis, and mixed storage should be avoided to prevent dangerous reactions. The storage place should be equipped with suitable materials to contain the leakage, so that it can be dealt with in time if an accident occurs.
If phosphorus tribromide leaks during the experiment, personnel in the leaked contaminated area should be quickly evacuated to a safe area, and quarantined to strictly restrict access Emergency responders need to wear self-contained positive pressure breathing apparatus, wear anti-acid and alkali work clothes, and do not directly contact leaks. In the case of small leaks, you can mix sand, dry lime or soda ash and collect them in a dry, clean and covered container. Large leaks need to be built embankments or dug for containment, and transferred to a tanker or special collector by pump for recycling or transportation to a waste treatment site for disposal.
In short, when using phosphorus tribromide, the experimenter must always keep in mind safety first and strictly follow the operating specifications to avoid accidents and ensure the safety and smooth operation of chemical research.
