What Are the Quality Standards for Refined Deoleated Naphthenic Acid
The quality of the alkanoic acid of refined diesel oil is important for the efficiency of diesel oil. The main ones are roughly the following ends.
The first is the value of the acid number. The acid number is also a measure of the amount of alkanoic acid content. Generally speaking, the acid number of refined diesel oil is controlled within a certain range. If the acid number is high, it indicates that the content of alkanoic acid is high, which is very unfavorable for the storage and use of diesel oil. Diesel with high acid value is easy to store containers and parts and cause corrosion, which shortens its service life. If the gold parts are raw and invaded, it will affect the normal performance of the diesel oil. Therefore, the acid value of general refined diesel oil should be kept at a low level to ensure the friendliness of diesel oil.
The requirements of the second process. The process reflects the steaming performance of diesel oil, and also the characteristics of alkanoic acid. A reasonable process can make diesel oil fully burn in the process. If the process is not good, even if the content of alkanoic acid meets the requirements, it will also ensure the good performance of diesel oil. For example, the narrow range may cause the diesel oil to be weak or weak, which may affect the combustion effect; the process may cause uneven diesel composition, which will have a negative impact on the performance of diesel oil. Therefore, the process of refined diesel oil is suitable for specific conditions, so as to ensure that the components such as alkanoic acid in diesel oil can act under the appropriate conditions.
Furthermore, the sulfur content should not be ignored. The direct forming part of sulphur-non-alkanoic acid, alkanoic acid together affects the quality of diesel oil. High sulfur content affects the corrosion of alkanoic acid, and the sulfide produced by combustion will cause environmental pollution. Therefore, the sulfur content of refined diesel oil is also limited, aiming to reduce the harm of its environment and the promotion of corrosion, to ensure the cleaning of the oil and the good quality of the surrounding environment.
In addition, the moisture and moisture content are also part of the production of refined diesel oil alkanoic acid. The high moisture content affects the fuel value of diesel oil, and may interact with alkanoic acid to add corrosion. The oil may block the oil circuit, affecting the normal supply of diesel oil, and causing heavy drying. Therefore, the refined diesel oil should maintain a low moisture content in order to maintain its excellent performance.
What is the production process of refining deoleated naphthenic acid?
The production process of refined anthracene tar cycloketoic acid is quite complicated, which is related to the key of chemical industry.
Initially, it is necessary to select refined anthracene tar as the material. This refined anthracene tar, when taken from the residue of high-quality anthracene oil refining, must have few impurities, and the content of anthracene should be high before it can be used.
Then, put this refined anthracene tar into a special reactor. The control of temperature and pressure in the kettle is crucial. With precise instruments, adjust the temperature to a suitable degree, about [X] degrees Celsius, and increase the pressure to [X] megapascals. Under this temperature and pressure, add an appropriate amount of catalyst. This catalyst is mostly a special metal salt or organic compound, which can promote the speed of reaction and increase the rate of yield.
Subsequently, a specific gas, or oxygen, air, etc., is introduced to make the anthracene tar oxidize under the action of the catalyst and gas. During this reaction, the molecular structure gradually changes, and the embryonic form of cycloketoic acid begins to appear. However, during the reaction process, it is necessary to closely monitor various parameters to prevent abnormalities caused by changes such as sudden rise in temperature and runaway pressure.
After the reaction is completed, the product contains unreacted raw materials, by-products and catalyst residues in addition to cycloketoic acid. Then by distillation, according to the difference in the boiling point of each substance, separation and purification. First, the low boiling point is steamed out, followed by cycloketoacid, and the rest are impurities with high boiling point retained at the bottom of the kettle.
The cycloketoacid obtained by distillation still contains some impurities, which need to be refined by extraction and crystallization. Select an appropriate extractant, extract the cycloketoacid from the mixture, and then cool down to crystallize to obtain pure cycloketoacid crystals. After these several processes, the refined anthracene tar can be converted into high-purity cycloketoacid to meet the needs of the chemical industry.
What are the precautions in the storage and transportation of refined deoleated naphthenic acid?
Refined fuel should retain acid in the process of storage, and pay attention to general matters.
Where it is stored, the first weight should be used. It must be dry, dirty and well-connected, and must not be exposed to direct light, nor should it be near fire or fire sources. This acid resistance may be dangerous due to high temperature or open flames, such as the risk of burning or explosion. If it is placed in the moisture, it may cause the container to rot and cause leakage.
Containers are also essential. It is necessary to use corrosion-resistant materials, such as special plastics and alloys. Ordinary gold containers are easily invaded by acid, causing the container to break and the acid to be outside. And the container needs to be well-packed to prevent acid from escaping, staining the environment, and preventing external water vapor and water from mixing in, and the product of shadow acid.
It is necessary to ensure that the tool can withstand the acid and prevent leakage. People must be well-versed and familiar with the emergency treatment method. On the way, it is appropriate to travel peacefully, avoid emergencies, severe bumps, and prevent container collisions and breakage.
The same, the document needs to be complete, and the information of the acid, characteristics, quantity and other information should be clearly stated, so as to check and rescue personnel along the way. In the event of a leakage accident, it is urgent to evacuate the crowd, isolate the crowd, and properly clean up and deal with it by people. Do not be careless. In addition, the storage of refined fuel oil and acid protection is not guaranteed, and each product should be carefully prepared to ensure complete security.
What are the advantages of refining deoleated naphthenic acid compared to other similar products?
Anthracene lubricating oil naphthenic acid has obvious advantages over other similar products. Anthracene lubricating oil naphthenic acid is extracted and refined in a specific environment, so its quality is pure and stable.

Gu Yun: "If you want to be good at your work, you must first sharpen your tools." This naphthenic acid helps the device like a sharp blade, and it works smoothly.
Second, the chemical stability. In case of temperature change or oxygen corrosion, it is not easy to change, and it can maintain its lubrication function in a wide temperature domain. On the other hand, other types, or due to temperature change and thinning loss, or by oxygen corrosion and quality deterioration, but this naphthenic acid is not, and its good state is always maintained. If pine and cypress are cold-resistant and heat-resistant, they are evergreen in all seasons.
Third, the ability to clean and disperse is excellent. During the operation of the machine, the generated scale and impurities can be dispersed and suspended, so as not to accumulate and prevent it from damaging the machine. Like a cleaner, the inside of the instrument is clean, and it is kept unobstructed. Other products may not be strong enough here, causing scale accumulation and mechanical diseases.
Fourth, it has good compatibility with materials. It can be at ease with all kinds of metals, sealing materials, etc., and will not be damaged. This is like a harmonious neighbor, coexisting without dispute, and protecting the integrity of the equipment, so that it can serve for a long time without fear.
