Triethyl Phosphate

Triethyl phosphate, a chemical product, is also stable in its properties, and has a weak taste in its color solution. It dissolves in multiple solvents and can also be miscible in water. Its method is to take phosphoric acid or its derivatives and esterify them with ethanol. Uses are widely used, especially in the fields of engineering, engineering, and scientific research.
First, triethyl phosphate is a good flame retardant. It is made in plastics, rubber, rubber, and fat, and is added to it, which can improve its fire resistance. The chemical contains phosphorus atoms, which decompose to form a multi-phosphorus oxide compound, forming a protective compound, blocking oxygen, and preventing the spread of fire. Therefore, modern flame retardant materials are often used to help.
Second, it is soluble. Among its properties, it is compatible with many compounds, which can help to dissolve dyes, lipids, oils, and multi-component synthetic raw materials. It is used for chemical production and production, and is widely used. In addition, it is also used for extraction in the process of extraction in the process of extraction in the process of extraction, which is conducive to component distribution and improves the quality of the product.
Third, it can be used for the synthesis of specific ingredients such as oil and weeding. It is also used to synthesize phosphate precursors and promote the synthesis of phosphate compounds.
Fourth, it is often used as a catalyst for fuel addition. Aviation, aerospace and other fuels are mixed to improve the combustion performance of triethyl phosphate esters to improve safety and efficiency. In some practical synthesis, it is used as a catalyst to promote the reaction rate.
And because of its low toxicity and environmental friendliness, it has been gradually developed by the industry. As mentioned above, triethyl phosphate is an indispensable multi-functional product in the chemical industry, materials, engineering, and other industries.

Triethyl phosphate, chemical formula C6H15O4P, if it has no color and a light taste, it is formed by esterification of phosphoric acid and ethanol. Its properties are moderate and non-flammable, but it can be an organic solvent. Triethyl phosphate, with good stability, is not easy to decompose at room temperature and pressure, and has a slight hydrolysis in contact with water. For a long time, ethanol and phosphoric acid are produced. Mixed with strong acid and alkali, it is easy to decompose. When heated to high temperature, there will be drastic changes, and it will decompose and release irritating gases.
Its reaction to organic oxidants is smooth, and the reaction to reducing agents is not intense. It can hold a variety of organic substances and dissolve fat and wax, so it is widely used as a solvent. In organic synthesis, it can be used as an intermediate or a phosphorus source, and can also be used to initiate some polymerization reactions. Its phosphorus atom is in pentavalent, the power supply ability is weak, and it is difficult to react directly with halogens. However, it can complex with some metal salts to form coordination compounds.
Although it does not fiercely support combustion in case of fire, it can release smoke of phosphorus oxides and carbon oxides when overheated. Although the chemical properties are relatively stable, they begin to change when they encounter strong oxidation or strong reduction conditions. It has no obvious corrosion effect on ordinary metals, but it can be exposed to iron and zinc for a long time, or it can cause micro-rot.
Soluble in most organic solvents such as alcohols, ethers, and esters, and can also be dissolved in a small amount of water. When exposed to ammonia or amines, it can form amine salts, and the chemical reaction of rattan is relatively warm. It is drug-free, It is commonly used as a flame retardant because it releases phosphoric acid when heated, which can react with combustible materials to form a non-flammable film layer. It can also be used to improve the properties of plastics, increase flexibility and reduce static electricity. Paints, glues, plasticizers and many industrial fields have their traces.
Review its properties, triethyl phosphate has stable chemical properties, but it should avoid hot topics and strong acids and alkalis, and be careful to coexist with fluorine and chloride. Use its stability, a wide range of processes, and endless uses.

Triethyl phosphate is mild in nature, but it is flammable and slightly toxic. The method of storage must be handled with caution. Choose a cool and ventilated place to avoid direct sunlight. The reservoir should be sealed and corrosion-resistant, such as galvanized iron drums or glass containers, and should not be filled with plastic thin containers, for fear of chemical reaction with the container and damage. The reservoir should be kept away from fire and heat sources, and should not be co-located with oxidizing agents, reducing agents, acids, alkalis, etc., to prevent the reaction from turning into flames. The indoor temperature should be maintained at room temperature, so that the temperature difference should not be too large, and the humidity should be moderate to prevent condensation and rot, which will affect its purity and nature.
When transporting, it must be properly sealed in a special container, and it must not be overloaded to prevent shock, collision and leakage. When loading and unloading, the action should be gentle to prevent friction sparks. The transportation vehicle must have warning signs, and do not mix with food, feed, etc. In case of overturning or leakage during transportation, it should be adsorbed with sand and activated carbon, and destroyed in a centralized manner. It must not be dumped on the spot to avoid polluting the soil and water sources. If there is a hot topic or fire during transportation, it should be treated with dry powder and carbon dioxide fire extinguishers. Do not douse with water to prevent the spread.
If the skin is accidentally touched during storage or transportation, it should be rinsed with plenty of water as soon as possible. Workers must wear protective gloves, goggles, gas masks and other labor protective gear when operating. Check the tightness of the container every time and dispose of it immediately if leakage is found. Do not be negligent. All storage data and transportation records should be registered in detail for inspection and traceability. When disposing of discarded containers, be sure to clean them thoroughly before they can be reused or destroyed according to regulations.
Looking at the method of storage and transportation, the most important thing is to be cautious, strictly abide by the system, and take prevention as the foundation to ensure the safety of personnel and the environment.

Triethyl phosphate, with chemical properties of stable, commonly used as a solvent and flame retardant, and also found in pesticides. Its physicochemical properties are slightly pungent in nature, and it is suspected of being flammable. When used in fortifications, be especially careful. This substance is slightly volatile, and if the gas escapes outside, people will inhale it for a long time, causing dizziness, fatigue, sore throat, cough and other symptoms. Although the toxicity is lower than that of various phosphide compounds, it should not be ignored. If it comes into contact with the skin, it will cause more tingling and inflammation, and it will become a rash for a long time. Easy to take by mouth, light vomiting and diarrhea, even severe gastrointestinal pain, if ingested in large quantities, it may cause damage to the liver and kidneys, and even endanger life.
Triethyl phosphate enters the body, is mainly metabolized by the liver, and is excreted with urine. However, some scholars have found that long-term exposure to this may affect the nervous system, causing cognitive impairment or sensory disorders. Studies have also pointed out that although its decomposition product phosphate ion is one of the elements required by the human body, excessive intake will be harmful. If young children or frail people are exposed to it, the impact will be particularly severe, and it may damage their health.
The state has strict regulations on the salinity of triethyl phosphate for industrial use. Protective equipment must be worn to ensure ventilation, and the dirt should not be dumped at will to prevent environmental damage. Operators should check their bodies every day, and if there is any abnormal omen, they should take a break from work and seek medical treatment. As for food and drinking water, if it is mistakenly mixed in a small amount, it is not enough to cause harm. However, it accumulates over time, and it is worry-free. It cannot be relied on. With its artificial synthesis, it is not born naturally, and it is not easy to encounter in the folk. Only chemical workers and experimenters should take special precautions.
Although triethyl phosphate is widely used, human health needs to be given priority first. It should not be taken lightly, and it should be well protected to ensure worry-free. Just ask whether this thing can be used safely, but you must be careful and not take it lightly.

The chemical name of triethyl phosphate is Triethyl Phosphate, and the molecular formula is C H O P. Although there are different methods for preparation in ancient and modern times, the esterification method of phosphoric acid and ethanol as raw materials is the most important in modern technology. The principle is that ethanol and phosphoric acid are esterified under a catalyst and suitable temperature conditions to generate triethyl phosphate and by-product water. For specific operations, anhydrous phosphoric acid is mixed with excess ethanol, placed in an acid-resistant vessel, and heated under constant temperature conditions. Sulfuric acid or p-toluenesulfonic acid is used as a catalyst, and the reaction lasts for several hours. When the system is fully reacted, impurities in the product coexist with unreacted raw materials, fractionation must be carried out, residual heat is taken to evaporate ethanol, followed by water washing, stripping the catalyst and unreacted phosphoric acid, and the remaining solution is re-distilled under reduced pressure to obtain pure triethyl phosphate.
In addition, there are also those who react with phosphorus oxychloride and ethanol. The formula is: POCl
and ethanol are slowly mixed under cooling conditions, and an alkaline neutralizing agent is added dropwise. After the reaction is completed, the by-product hydrogen chloride and the remaining impurities are separated. Triethyl phosphate can also be obtained by washing and refining and vacuum fractionation. Although this method is fast-reacting, if the equipment is not good, there is a risk of hydrogen chloride escaping, so it is generally less used for large-scale production.
In the process, washing and stratification operations are also very important. Decanting each layer of substances and removing non-target components can improve the purity and yield of the product. In today's factories, automated equipment is often used to control temperature and pressure, and the operation is standardized to ensure that the reaction is thorough and safe. The triethyl phosphate produced by it is often used as a solvent, flame retardant and organic synthesis intermediate, and is widely used. In summary, the direct esterification process of phosphoric acid and ethanol is the most commonly used, and its operation is simple, the raw materials are easy and cheap, and the yield is also high, which is especially popular.
