What are the Chemical Properties of Ammonium Phosphorus Fluoride
Ammonium (Ammonium), phosphorus (Phosphorus), fluoride (Fluoride) have unique chemical properties, and they also have specific reactions and effects on each other. The following is the detailed description of Jun:
- ** Properties of ammonium **: Ammonium ion ($NH_ {4 }^{+}$） has cationic characteristics, has a colorless appearance, and is often found in many ammonium salts. Its chemical activity is quite high, and it can combine with many anions to form corresponding ammonium salts. If combined with chloride ion ($Cl ^ {-} $) to form ammonium chloride ($NH_ {4} Cl $), this salt is easily soluble in water, and the aqueous solution is weakly acidic. Ammonium salts decompose easily when heated. Taking ammonium bicarbonate ($NH_ {4} HCO_ {3} $) as an example, they decompose into ammonia ($NH_ {3} $), carbon dioxide ($CO_ {2} $) and water ($H_ {2} O $) when heated.
- ** Properties of phosphorus **: Phosphorus contains a variety of allotropes, common ones are white phosphorus and red phosphorus. White phosphorus is soft in color and highly toxic. It has a very low ignition point of only 40 ° C. It is easy to spontaneously ignite in air and must be stored in water. Red phosphorus is dark red, non-toxic, and has a high ignition point of about 240 ° C. Its chemical properties are more stable than white phosphorus. Phosphorus easily reacts with oxygen in air to form phosphorus oxides. White phosphorus burns violently to form phosphorus pentoxide ($P_ {2} O_ {5} $), which is highly absorbent and is often used as a desiccant.
- ** Properties of fluoride **: Fluorides cover many compounds, among which fluoride ions ($F ^ {-} $) have a very small radius and are extremely electronegative. Many metal fluorides are unique in solubility, such as calcium fluoride ($CaF_ {2} $), which is insoluble in water, while sodium fluoride ($NaF $) is soluble in water. Hydrofluoric acid ($HF $) is an aqueous solution of hydrogen fluoride. It is a weak acid, but it is highly corrosive. It can corrode glass because it can react with silica ($SiO_ {2} $) in glass to form silicon tetrafluoride ($SiF_ {4} $) gas and water.
When the three interact, complex chemical reactions may occur. For example, some ammonium-containing phosphates and fluorides may exchange ions under certain conditions to form new compounds. Or in an aqueous solution system, the existence and reactivity of different ions will be affected by other ions, resulting in equilibrium movement, and then exhibit various chemical properties.
What is the production process of Ammonium Phosphorus Fluoride?
The method of making ammonium, phosphorus and fluorine is an important matter in the chemical industry. Ammonium is often obtained from the combination of ammonia and acid. Phosphate rock is often mined from phosphorus sources, and the quality of its refined phosphorus is analyzed after various treatments. Fluorine also has its source, or is taken from fluorite and other substances.
To make ammonium, phosphorus and fluorine, the first thing to do is to deal with its raw materials. The phosphate rock must be ground to increase its reaction surface. Following the chemical method, the phosphate rock should be combined with acids, such as sulfuric acid, which is the way to obtain phosphoric acid. In this process, pay attention to the control of temperature and concentration to ensure a smooth reaction.
The introduction of ammonium often introduces ammonia into the phosphoric acid solution. Ammonia and phosphoric acid combine to form different ammonium salts according to their proportions. In this step, it is also necessary to carefully adjust the degree of acid and base to obtain the state of ammonium-phosphorus synthesis.
As for the addition of fluorine, choose the appropriate fluoride, such as hydrogen fluoride or its salts. When adding fluorine, consider its reaction with ammonium and phosphorus to prevent harmful side effects. Control its amount, required for the composition of ammonium-phosphorus-fluorine.
When preparing, temperature, pressure, and reaction time are all important factors. Constant its temperature, stabilize its pressure, keep its time, and keep the reaction in the desired direction. And after the reaction, there is a process of purification. Remove impurities, purify ammonium, phosphorus, and fluorine, and improve its quality.
All these steps are interconnected, and all chemical techniques are required to produce high-quality ammonium phosphorus fluoride, which can meet the requirements of agricultural fertilizers and industrial fields.
What are the precautions for Ammonium Phosphorus Fluoride during use?
Ammonium (Ammonium), phosphorus (Phosphorus), fluoride (Fluoride) substances involved in the use of the process, there are many need to pay attention to.
Ammonium substances, mostly exist in the form of ammonium salts. First, ammonium salts are easy to decompose when heated, and when stored and used, they should be avoided in a high temperature environment. Otherwise, ammonium salts decompose, or the product may be impure, which will affect the subsequent reaction or use effect. Second, ammonium ions will react with alkalis to generate ammonia and water. Therefore, ammonium substances should not be mixed with alkaline substances, otherwise ammonia will escape, not only causing nitrogen loss, but also increasing the internal pressure of the container due to the large amount of gas, which will cause danger.
Phosphorus elements include white phosphorus, red phosphorus and other allotropes. White phosphorus has a very low ignition point, only about 40 ° C, and is prone to spontaneous combustion in the air. When taking white phosphorus, be sure to use tweezers to clamp it, and do not touch it directly with your hands. Because it is highly toxic, it should be cut underwater, and it should be immersed in water when storing to prevent spontaneous combustion from causing fires. Although red phosphorus is relatively stable, it should not be near open flames because it is also at risk of burning due to heat or friction. If phosphorus-related compounds, such as phosphoric acid, are corrosive, wear protective clothing, protective gloves and goggles when using, and avoid contact with skin and eyes. Once contaminated, rinse with plenty of water immediately and seek medical attention in time.
Fluoride, many toxic. Gaseous fluorides, such as hydrogen fluoride, have a strong pungent odor and have a serious corrosive and irritating effect on the respiratory tract. When using, it must be operated in a well-ventilated environment or in a fume hood to prevent respiratory damage caused by inhalation of hydrogen fluoride gas. Solid fluorides, such as sodium fluoride, should not be imported. If you accidentally ingest them, you should seek medical attention immediately. At the same time, fluoride has a corrosive effect on glass. Glass containers should not be used for storage, and corrosion-resistant materials such as plastics should be used.
In short, when using ammonium, phosphorus, and fluoride-related substances, you must fully know their characteristics and operate in strict accordance with regulations to ensure the safety of personnel and the smooth progress of experiments and production activities.
