Diesel with a high aniline point is generally considered desirable as automotive fuel because it indicates better solvency and reduced risk of fuel system issues. Higher aniline points suggest that the fuel can better resist oxidation and thermal degradation, leading to improved engine performance and longevity. Additionally, it may provide better lubrication properties, which can enhance engine efficiency. However, other factors such as cetane number and emissions must also be considered for overall fuel quality.
What else can I help you with?
What is the formula used in diesel index calculation?
diesel index = aniline point *API(1/100)
What is the difference between Aniline Point and Mixed Aniline Point?
There is no any such difference between Aniline point and mixed Aniline point . . . . .
Cetane number equals Diesel Index - 3?
Cetane number is derived from an engine test. It measures the ignition characteristics of diesel fuel, (which detonates under pressure). The higher the Cetane number, the greater the resistance to pre-ignition. A high cetane diesel can be used in high compression (more effcient) engines. Diesel Index (DI) is a calculation allowing an approximation of Cetane No., when there is no Cetane Test Engine available. The DI is derived from the Analine Point. The Analine Point is a temperature, where analine and the (diesel) sample become completely miscible. DIESEL INDEX = ((ANILINE POINT(DEG F))(API GRAVITY))/100 A higher aniline point (and therefore a lower aromatic content) in diesel oil is desirable, in order to prevent autoignition in diesel engines.
What is the aniline point of kerosene?
The aniline point of kerosene is 60-69 oC.
Is the aniline point highest for arromatics?
no aromtics show the low aniline point....because higher the aniline point higher the pariffinic content and lower the aromatic content
What the deferent between aniline point and the poling point?
aniline point is the lowest temp in f in wich equal volume of aniline and dieasel are completely missble. Poling point is that temp in which aromatic compounds are not freezed
Is Aniline point is a property of lpg?
no
How can you improve aniline point of an oils?
To improve the aniline point of oils, one can fractionate the oil to remove lighter components, adjust the chemical composition to increase the aromatic content, or add specific additives that can raise the aniline point. Additionally, removing any contaminants or impurities that can lower the aniline point can also help improve it.
What is the significance of aniline point test?
The aniline point test is significant in assessing the aromatic content of petroleum products, particularly fuels and lubricants. It measures the lowest temperature at which equal volumes of aniline and the sample will mix, indicating the degree of saturation and the presence of aromatic hydrocarbons. A lower aniline point suggests a higher aromatic content, which can affect the fuel's properties, such as its combustion efficiency and emissions. This test is essential for ensuring compliance with environmental regulations and optimizing fuel performance.
Which type of titration involved in the estimation of aniline?
Aniline can be estimated using acid-base titration. In this process, a known concentration of acid is added to a solution containing aniline until the equivalence point is reached, indicated by a color change due to the formation of a salt. This helps in determining the concentration of aniline present in the solution.
Why is it that aniline has a high boiling point to phenol and phenol has a high boiling point than toluene and toluene has a high boiling point than benzene?
Aniline has a higher boiling point than phenol because aniline can form strong hydrogen bonds due to the presence of an amino group. Phenol has a higher boiling point than toluene because phenol molecules can form intermolecular hydrogen bonds because of the hydroxyl group. Toluene has a higher boiling point than benzene due to the presence of a bulky methyl group which increases Van der Waals forces between toluene molecules.
What is the flash point difference between diesel and gasoline?
The flash point difference between diesel and gasoline is that diesel has a higher flash point than gasoline. Diesel typically has a flash point of around 125-180 degrees Celsius, while gasoline has a flash point of around -40 to -60 degrees Celsius.
